2.2.0

Features:

  • New feature: Video relevance. Video relevance is a score calculated based on the age of the video (time since upload) and the number of views, comments and reactions it has. The weight of each of these factors can be configured through VideoRelevanceWeights config value (using the new setVideoWeights mutation). The relevance score is automatically recalculated for a video:
    • every hour,
    • in case its number of views increased and is now divisible by VideoRelevanceViewsTick config value,
    • in case its number of vidoe's reactions / comments has changed.

Config values:

  • New config value: VideoRelevanceWeights - used to configure the weights of the factors used to calculate video relevance score.
  • New config value: VideoRelevanceViewsTick - used to configure the number of views after which the video relevance score should be recalculated.

Schema/API changes:

  • New field: Video.videoRelevance - video relevance score.
  • New mutation: setVideoWeights - used to set the value of VideoRelevanceWeights config.
  • New query: topSellingChannels - used to retrieve channels with highest nft sales volume in a given period of time.
  • New query: endingAuctionsNfts - used to retrieve nfts that are on active english auction, ordered by the time left until the auction ends.
  • Changes to mostViewedVideosConnection query:
    • INNER JOIN to video_view_events table is now used, which means videos with 0 views will no longer appear in the results;
    • in case both periodDays arg is provided and viewsNum is part of the orderBy clause, the videos are now ordered by the number of views in the specified period (not the number of views in general)
  • Added integration w/ the new relevance score recalculation service in terms of recalculating scores on addVideoView, setVideoReactions and excludeContent mutations.

Mappings:

  • Added integration w/ the new relevance score recalculation service, responsible for recalculating the score for all videos every hour, as well as in case of the following events:
    • ReactVideo metaprotocol message,
    • CreateComment metaprotocol message,
    • DeleteComment metaprotocol message,
    • ModerateComment metaprotocol message,

Other:

  • Fixed docker build and added automatic joystream/orion docker image publishing to docker hub.
  • Improved data migration process during deployment w/ the new OffchainMigration service, which can export and import database entities as well as individual field values.

2.1.0 (Ephesus release)

Schema/API changes:

  • cumulativeRewardClaimed field has been added to Channel
  • new event.data types are now supported:
    • ChannelRewardClaimedEventData
    • ChannelRewardClaimedAndWithdrawnEventData
    • ChannelFundsWithdrawnEventData
    • ChannelPayoutsUpdatedEventData
    • ChannelPaymentMadeEventData
  • New MetaprotocolTransactionResult variant: MetaprotocolTransactionResultChannelPaid
  • New DataObjectType variant: DataObjectTypeChannelPayoutsPayload

Mappings:

  • Added support for handling both pre and post-Ephesus version of the following events updated in Ephesus:
    • Members.MemberInvited
    • Members.MemberRemarked
  • New mappings for the following events:
    • Content.ChannelPayoutsUpdated
    • Content.ChannelRewardUpdated
    • Content.ChannelRewardClaimedAndWithdrawn
    • Content.ChannelFundsWithdrawn
  • Support for new MemberRemark metaprotocol transaction type: makeChannelPayment (direct channel payment)

Bug fixes:

  • Fixed: Events that had a relationship to an auction bid through data->>'winningBid' were not properly hidden when the bid was excluded from the visible data thorugh excludeContent functionality. This was causing errors such as Cannot return null for non-nullable field OpenAuctionBidAcceptedEventData.winningBid when querying for OpenAuctionBidAcceptedEventData events.

2.0.0

Orion v2 is a major architecture change compared to Orion v1:

  • No proxying to external Query Node: Event processing is now part of Orion, the state is unified in a single database (PostgreSQL) instead of being spread between Joystream Query Node and Orion.
  • Subsquid framework is now used for event processing and GraphQL api generation.

For detailed overview of the new architecture, see the developer guide

External api changes

Queries

  • Significantly improved query speed should be observed in most cases (the average query should be 2x faster in Orion v2, see the latest benchmarking results)

Changes:

  • Generally reduced set of supported queries and queryable entity fields. Only queries for the entities based on members, content and storage Joystream modules, which are relevant to Atlas, are now supported by Orion. Additionally, fields like ownerCuratorGroup, channel's collaborators etc., which are not yet supported by Atlas are also not yet supported in Orion v2.
  • Event interface has been replaced with EventData union, as GraphQL interfaces are not supported in Subsquid. This affects the way events query works, as well as removes specific event queries (like categoryCreatedEvents, videoReactedEvents etc.)
  • Some redundant relationships were removed (for example, entities that had relation to both Video and video's Channel, now may only have relation to a Video. Similarly, entities that contained ownerMember/ownerCuratorGroup fields, but also had a relation to Channel, no longer include redundant channel ownership information), which were previously required to workaround lack of deeply nested filtering. For the same reason, other relations were replaced with more specific ones (for exmaple auction instead of video). Some examples of this include:
    • Auction bid canceled event has a relation to bid instead of video,
    • Auction bid made event no longer has bidAmount, previousTopBid and previousTopBidder. They can all be derived from the related bid instead,
    • Auction canceled event has a relation to auction instead of video,
    • Event with winningBid field no longer contian relations like video or winner, as they can be derived from winningBid,
    • Most of other nft-related events now have a relation to nft instead of video.
  • NFT's transactionalStatus and transactionalStatusAuction is now represented as a single transactionalStatus which includes TransactionalStatusAuction as one of the variants.
  • Entity fields like nftOwnerMember, isNftOwnerChannel, nftOwnerCuratorGroup have been relaplaced with a single NftOwner union.
  • Channel.followsNum, Channel.videoViewsNum and Video.viewsNum fields have been added and can now be used for filtering, sorting etc. (in Orion v1 fields like Channel.follows, Channel.views and Video.views also existed, but had limited functionality)
  • Some small differences in the representation of empty values:
    • Auction.buyNowPrice: 0 => null
    • Comment.reactionsCountByReactionId: [] => null
    • DistributionBucketFamilyMetadata.areas: [] => null
    • VideoCategory.description: '' => null
  • Some small differences in types:
    • StorageBag.owner.channelId: number => string
  • DistributionBucketFamilyMetadata.areas is now a jsonb field, so it was possible to skip one level of nesting:
    • DistributionBucketFamilyMetadata.areas.area => DistributionBucketFamilyMetadata.areas
  • Some fileds were renamed:
    • Event.createdAt => Event.timestamp
    • *Event.contentActor => *EventData.actor
    • NftBoughtEvent.member => NftBoughtEventData.buyer
    • Membership.memberBannedFromChannels => Membership.bannedFromChannels
  • Some entity ids are not backward-compatible:
    • DistributionBucketFamilyMetadata
    • StorageBucketOperatorMetadata
    • DistributionBucketOperatorMetadata
    • MemberMetadata
    • Event
  • Some entities no longer have ids, as are now stored as jsonb objects in the parent table:
    • GeoCoordinates
    • NodeLocationMetadata
    • DistributionBucketFamilyGeographicArea
    • CommentReactionsCountByReactionId
    • VideoReactionsCountByReactionType
  • In Orion v1 providing a non-existing category id resulted in a creation of empty video category (without any name or description). Such categories are no longer created, providing non-existing category as part of ContentMetadata results in setting Video.category to null instead.
  • Channel.activeVideoCounter and VideoCategory.activeVideoCounter fields have been removed, instead custom extendedChannels and extendedVideoCategories queries have been introduced, which allow retrieving the number of active videos per channel/category.
  • createdAt and updatedAt fields are no longer automatically added to entities in Subsquid, so most of the entities no longer include them (unless they were explicitly required by Atlas).
  • Many-to-Many entity relationships are not supported in Subsquid, so those relationships were refactored to 2-side Many-to-One relationships with a specific "join entity". This means that some queries may now require one more level of nesting, ie.:
    • Channel.bannedMembers.id => Channel.bannedMembers.member.id
    • Auction.whitelistedMembers.id => Auction.whitelistedMembers.member.id
    • Membership.whitelistedInAuctions.id => Membership.whitelistedInAuctions.auction.id
    • StorageBucket.bags.id => StorageBucket.bags.bag.id
    • DistributionBucket.bags.id => DistributionBucket.bags.bag.id
    • StorageBag.storageBuckets.id => StorageBag.storageBuckets.storageBucket.id
    • StorageBag.distributionBuckets.id => StorageBag.distributionBuckets.distributionBucket.id
  • Language entity has been removed. Language is now represented as a simple ISO code string.
  • DataTime format is slightly different:
    • 2022-01-01T00:00:00.000Z => 2022-01-01T00:00:00.000000Z
  • { entity { relatedEntityId } } syntax is not supported in Subsquid, { entity { relatedEntity { id } } } has to be used instead
  • the type of entity id property is now String (previously ID)
  • entityByUniqueInput queries are no longer supported. The new entityById queries can be used instead in some cases.
  • admin query (kill switch) was renamed to getKillSwitch
  • categoryFeaturedVideos and allCategoriesFeaturedVideos queries do not exist anymore. Instead, videos featured in a category can be accessed through category.featuredVideos relation
  • mostViewedCategories and mostViewedCategoriesAllTime queries have been removed (currently unused by Atalas)
  • discoverChannels and promisingChannels queries has been removed in favor of a new more generic/reusable mostRecentChannels query (searching among X most recent channels)
  • popularChannels query has been removed, as the same results can now be obtained with channels/extendedChannels query with orderBy: videoViewsNum_DESC, limit: 15
  • top10Channels query has been removed as the same results can now be obtained with channels/extendedChannels query with orderBy: followsNum_DESC, limit: 10
  • mostViewedChannelsConnection and mostFollowedChannelsConnection queries have been removed (currently unused by Atalas)
  • top10VideosThisWeek and top10VideosThisMonth queries have been removed, as the same results can now be obtained with mostViewedVideosConnection(limit: 10, where: $where, periodDays: (7|30), orderBy: createdAt_DESC) query
  • search query is temporarily not supported (unused by Atals)
  • channelNftCollectors query now takes channelId: String! input instead of where: ChannelNftCollectorsWhereInput. orderBy variants have been reduced to amount_ASC and amount_DESC
  • ChannelFundsWithdrawnEventData.account as well as ChannelRewardClaimedAndWithdrawnEventData.account are now null in case the funds destination was Council and account address otherwise (periously this field contained a json string representing the serialized ChannelFundsDestination enum)
  • Event ids are now assigned sequentially (00000001, 00000002, 00000003 etc.) instead of being {blockNumber}-{indexInBlock}. Because all events now live in the same database table, {blockNumber}-{indexInBlock} would no longer be a unique identifier when dealing with metaprotocol events (as there can be multiple metaprotocol events triggered by the same runtime event)
  • MetaprotocolTransactionStatus has been renamed to MetaprotocolTransactionResult and now also includes variants that have been previously represented by optional fields of MetaprotocolTransactionSuccessful (MetaprotocolTransactionResultCommentCreated, MetaprotocolTransactionResultCommentEdited etc.). To check if the transaction was generally successful you can now use event.result.isTypeOf !== 'MetaprotocolTransactionResultFailed'
  • MetaprotocolTransactionErrored variant has been replaced with MetaprotocolTransactionResultFailed and may include slightly different error messages. The error messages should be completely removed and replaced with error codes in the future.
  • The default limit for number of returned rows when no limit was provided in Orion v1 was 50. In Orion v2 there is no default limit(!)

New query features

  • (Subsquid) Deeply nested filtering (for example: videos(where: { channel: { avatarPhoto: { storageBag: { storageBuckets_some: { id_eq: "1" } } } } })) is now supported, as well as nested field queries
  • (Subsquid) There are a few new properties for where inputs of queries, like filed_isNull, field_containsInsensitive, field_not_(eq|in|contains|containsInsensitive|endsWith|startsWith)
  • It is now possible to query the resolvedUrls property of any StorageDataObject (for example: { videoById(id: "1") { media { resolvedUrls } } }). The Orion v2 GraphQL server will then resolve it to a list of available asset urls, based on its internal distributor nodes data cache. If you provide x-client-loc header, Orion v2 will additionally prioritize distributor nodes closest to the provided location when resolving the url. The value for x-client-loc should be provided in lat,lon format, where lat is the latitude (-90, 90) and lon is the longitude (-180, 180), for example: x-client-loc: 42.557127,-103.886719. You can also provide x-asset-urls-limit to specify the maximum number of urls to return per asset (by default all available urls will be returned).
  • Censored channels and videos belonging to censored channels, as well as channels/videos excluded by the gateway operator via excludeContent mutation are now filtered-out from all query results by default. The same applies to videos belonging to categories not supported by the gateway (see: setSupportedCategories operator mutation and operator queries for more details)
  • Video comments can also be excluded by the gateway operator via excludeContent mutation, but they are not filtered out from the query results in that case. Instead, their text is hidden and they can be identified by having isExcluded property set to true.
  • Entities like VideoViewEvent, Report and ChannelFollow are now part of the Subsquid GraphQL input schema / PostgreSQL database schema. In Orion v1 similar entities were stored in a local MongoDB database and some of them were exposed for the gateway operator via authorized queries like reportedChannels, reportedVideos. In Orion v2 the api includes autogenerated queries like videoViewEvents, videoViewEventsConnection, reports, reportsConnection, channelFollows, channelFollowsConnection etc. with all the features provided by Subsquid's Openreader. However, just like in Orion v1, this data is also hidden from the public view as it includes sensitive information like IP addresses of the users. Only the Gateway operator is able to query this hidden data (see operator queries for more details).
  • VideoHero entity includes additional fields (video, activatedAt)
  • Featured nfts: OwnedNfts now have isFeatured property can be set by the Gateway operator.

New queries

  • getVideoViewPerIpTimeLimit: allows retrieving the current value of VideoViewPerIpTimeLimit config value (see also: setVideoViewPerIpTimeLimit under operator mutations)
  • In order to optimize Atlas queries that do complex filtering of Event entities, like GetNotifications, GetNftHistory and GetNftActivities, a few new entities were introduced which include a reltionship to Event (this was not possible in Orion v1, as there wasn't a single Event entity). The new entities (and associated queries) are: Notification (notifications, notificationsConnection), NftHistoryEntry (nftHistoryEntries, nftHistoryEntriesConnection) and NftActivity (nftActivities, nftActivitiesConnection).
  • historical VideoHero snapshots can now be queried using new autogenerated queries like videoHeros, videoHeroById etc.

Bug fixes

  • Auction.topBid can no longer be a canceled bid (this was previously possible in OpenAuction). In case the top bid gets canceled, the next best bid is set as Auction.topBid. In case there is no next best bid, Auction.topBid is set to null.
  • In Orion v1 (Query Node), when a member placed a bid in OpenAuction, it was possible for their bid in an old, already finalized auction for the same nft to get canceled (even if it was already a winning bid). Now this will no longer happen.
  • Video.pinnedComment relation was incorrectly declared in Orion v1 (Query Node) input schema, which resulted in some comments, which were never actually pinned, being returned as Video.pinnedComment. This should no longer happen in Orion v2.
  • In Orion v1 (Query Node) sometimes the createdAt field of an entity (like Memberships) would be incorrectly modified on update. This will no longer happen in Orion v2, as fields like createdAt need to be added explicitly in Subsquid and are no longer automatically managed.
  • Using property aliases was not working in Orion v1 (for example: channels { channelId: id }), this is no longer an issue in Orion v2.
  • OwnedNft.creatorRoyalty was incorrectly calculated in Orion v1 (rounded down to nearest integer), this has been fixed in Orion v2, so that now creatorRoyalty can have non-integer value (like 0.5).

Operator queries

  • An authorized operator, who provided a valid x-operator-secret HTTP header, can see any entities hidden from the public view in the query results (unless explicitly filtered out by the query where conditions or otherwise). Those include:
    • Censored (by the DAO) channels & videos and their related entities (nfts, auctions, comments, reactions, metadata entities etc.),
    • Excluded (censored by the Gateway) channels, videos and their related entities (nfts, auctions, reactions, metadata entities etc.),
    • Any content not belonging to a category currently supported by the Gateway,
    • Other entities hidden from public view for security reasons:
      • VideoViewEvents,
      • Reports,
      • ChannelFollows,
      • NftFeaturingRequests.

Subscriptions

  • stateSubscription has been renamed to processorState, properties have been reduced to just lastProcessedBlock

User Mutations

Changes

  • addVideoView:
    • no longer requires channelId and categoryId as input
    • now only increases number of video views if the request is a unique request per ip-videoId pair in the last Config.VideoViewPerIpTimeLimit seconds (to prevent abuse). This limit can be set via environment variable or through setVideoViewPerIpTimeLimit operator mutation.
    • added boolean was added to mutation result to indicate whether a new view was added or not
  • followChannel:
    • channel id is now returned in channelId field of the mutation result, instead of id
    • cancelToken is now returned as part of the mutation result. This token has to be used when unfollowing the channel to prevent arbitrarly triggering unfollow when there is not matching channel follow on the client side.
    • only one follow is now counted per client ip to prevent abuse.
    • added boolean was added to mutation result to indicate whether a new follow was added or not (depending on whether a matching follow already existed for given ip-channleId pair)
  • unfollowChannel
    • now additionally requires token as input (see followChannel changes)
    • removed boolean was added to mutation result to indicate whether the follow was removed or not (it is only removed if there is a matching follow per token-channelId pair)
  • reportChannel/reportVideo:
    • now only one report can be sent from given ip for given channel/video to prevent abuse.
    • created boolean was added to mutation result to indicate whether a new report was created

New mutations:

  • requestNftFeatured - allows users to make a request for a given nft to be featured by the Gateway. Operator can then read those requests using the new queries like nftFeaturingRequests. Functionally this feature is similar to reportChannel/reportVideo.

Operator mutations

Changes

  • All operator mutations now require x-operator-secret HTTP header to be provided, with value equal to OPERATOR_SECRET environment value. There is currently no distinction between secret used for content featuring and other operator activities.
  • setVideoHero
    • the history of video heros' set is now persisted in the database and is publicly accessible,
    • mutation result now only includes the id of the created VideoHero entity
  • setCategoryFeaturedVideos
    • the mutation result now only includes categoryId and number of featured videos set / unset

New mutations

  • setSupportedCategories - allows specifying which video categories are supported by the gateway. Content that doesn't belong to supported categories will not be displayed in query results. This includes the categories themselves, videos, nfts, auctions, comments, reactions etc.
  • setVideoViewPerIpTimeLimit - allows specifying the time after which a video view triggered from the same ip address will be counted again (see: addVideoView)
  • excludeContent - allows excluding specified channels/videos/comments from all query results. Can be used as a gateway-level mechanism to censor some of the content. Comments are the only entities that don't get completely filtered-out from query results when excluded. Instead, their text becomes hidden and isExcluded property is set to true.
  • restoreContent - effectively the opposite of excludeContent, can be used to make content appear in the query results again (if previously excluded).
  • setFeaturedNfts - allows the operator to provide the list of nfts (ids) that are currently featured by the Gateway. This will affect the isFeatured propety of the OwnedNft entity.
