Full Changelog: v0.34.1...v0.35.0

v0.34.1

$ docker pull graphprotocol/graph-node:v0.34.1

This a patch release that addresses a few issues

• Fixes an issue that caused an increase in data size of /metrics endpoint of graph-node. (#5161). Indexers are advised to skip v0.34.0 and use v0.34.1
• Fixes an issue that caused subgraphs with file data sources to skip non-deterministic errors that occurred in a file data source mapping handler.

v0.34.0

$ docker pull graphprotocol/graph-node:v0.34.0

What's New

• Substreams as Source of Triggers for Subgraphs - This update significantly enhances subgraph functionality by enabling substreams to act as a source of triggers for running subgraph mappings. Developers can now directly run subgraph mappings on the data output from substreams, facilitating a more integrated and efficient workflow.(#4887) (#4916)
• indexerHints in Manifest for Automated Pruning - This update introduces the ability for subgraph authors to specify indexerHints with a field prune in their manifest, indicating the desired extent of historical block data retention. This feature enables graph-node to automatically prune subgraphs when the stored history exceeds the specified limit, significantly improving query performance. This automated process eliminates the need for manual action by indexers for each subgraph. Indexers can also override user-set historyBlocks with the environment variable GRAPH_HISTORY_BLOCKS_OVERRIDE (#5032 (#5117)
• Initial Starknet Support - Introducing initial Starknet support for graph-node, expanding indexing capabilities to the Starknet ecosystem. The current integration is in its early stages, with notable areas for development including the implementation of trigger filters and data source template support. Future updates will also bring substream support. (#4895)
• endBlock Feature in Data Sources - This update adds the endBlock field for dataSources in subgraph manifest. By setting an endBlock, subgraph authors can define the exact block at which a data source will cease processing, ensuring no further triggers are processed beyond this point. (#4787
• Autogenerated Int8 IDs in graph-node - Introduced support for using Int8 as the ID type for entities, with the added capability to auto-generate these IDs, enhancing flexibility and functionality in entity management. (#5029)
• GraphiQL V2 Update - Updated GraphiQL query interface of graph-node to version 2. (#4677)
• Sharding Guide for Graph-Node - A new guide has been added to graph-node documentation, explaining how to scale graph-node installations using sharding with multiple Postgres instances. Sharding Guide
• Per-chain polling interval configuration for RPC Block Ingestors (#5066)
• Metrics Enhancements(#5055) (#4937)
• graph-node now avoids creating GIN indexes on array attributes to enhance database write performance, addressing the issue of expensive updates and underutilization in queries. (#4933)
• The subgraphFeatures endpoint in graph-node has been updated to load features from subgraphs prior to their deployment. (#4864)
• Improved log filtering performance in blockstream. (#5015)
• Enhanced GraphQL error reporting by including __schema and __type fields in the results during indexing errors (#4968)

Bug fixes

• Addressed a bug in the deduplication logic for Cosmos events, ensuring all distinct events are properly indexed and handled, especially when similar but not identical events occur within the same block. (#5112)
• Fixed compatibility issues with ElasticSearch 8.X, ensuring proper log functionality. (#5013)
• Resolved an issue when rewinding data sources across multiple blocks. In rare cases, when a subgraph had been rewound by multiple blocks, data sources 'from the future' could have been left behind. This release adds a database migration that fixes that. With very unlucky timing this migration might miss some subgraphs, which will later lead to an error assertion failed: self.hosts.last().and_then(|h| h.creation_block_number()) <= data_source.creation_block(). Should that happen, the migration script should be rerun against the affected shard. (#5083)
• Increased the base backoff time for RPC, enhancing stability and reliability under load. (#4984)
• Resolved an issue related to spawning offchain data sources from existing offchain data source mappings. (#5051)(#5092)
• Resolved an issue where eth-call results for reverted calls were being cached in call cache. (#4879)
• Fixed a bug in graphman's index creation to ensure entire String and Bytes columns are indexed rather than just their prefixes, resulting in optimized query performance and accuracy. (#4995)
• Adjusted SubstreamsBlockIngestor to initiate at the chain's head block instead of starting at block zero when no cursor exists. (#4951)
• Fixed a bug that caused incorrect progress reporting when copying subgraphs, ensuring accurate status updates. (#5075)

Graphman

• Graphman Deploy Command - A new graphman deploy command has been introduced, simplifying the process of deploying subgraphs to graph-node. (#4930)

Graphman

• Graphman Deploy Command - A new graphman deploy command has been introduced, simplifying the process of deploying subgraphs to graph-node. (#4930)

v0.33.0

What's New

• Arweave file data sources - Arweave file data sources allow subgraph developers to access offchain data from Arweave from within the subgraph mappings.(#4789)
• Major performance boost for substreams-based subgraphs - Significant performance improvements have been achieved for substreams-based subgraphs by moving substreams processing to the block stream.(#4851)
• Polling block handler - A new block handler filter polling for ethereum data sources which enables subgraph developers to run a block handler at defined block intervals. This is useful for use cases such as taking periodic snapshots of the contract state.(#4725)
• Initialization handler - A new block handler filter once for ethereum data sources which enables subgraph developers to create a handler which will be called only once before all other handlers run. This configuration allows the subgraph to use the handler as an initialization handler, performing specific tasks at the start of indexing. (#4725)
• DataSourceContext in manifest - DataSourceContext in Manifest - DataSourceContext can now be defined in the subgraph manifest. It's a free-form map accessible from the mapping. This feature is useful for templating chain-specific data in subgraphs that use the same codebase across multiple chains.(#4848)
• graph-node version in index node API - The Index Node API now features a new query, Version, which can be used to query the current graph-node version and commit. (#4852)
• Added a 'paused' field to Index Node API, a boolean indicating the subgraph’s pause status. (#4779)
• Proof of Indexing logs now include block number (#4798)
• subgraph_features table now tracks details about handlers used in a subgraph (#4820)
• Configurable SSL for Postgres in Dockerfile - ssl-mode for Postgres can now be configured via the connection string when deploying through Docker, offering enhanced flexibility in database security settings.(#4840)
• Introspection Schema Update - The introspection schema has been updated to align with the October 2021 GraphQL specification update.(#4676)
• trace_id Added to Substreams Logger (#4868)
• New apiVersion for Mapping Validation - The latest apiVersion 0.0.8 validates that fields set in entities from the mappings are actually defined in the schema. This fixes a source of non-deterministic PoI. Subgraphs using this new API version will fail if they try to set undefined schema fields in the mappings. Its strongly recommended updating to 0.0.8 to avoid these issues. (#4894)
• Substreams Block Ingestor Support - Added the ability to run a pure substreams chain by introducing a block ingestor for substreams-only chains. This feature allows users to run a chain with just a single substreams endpoint, enhancing support beyond RPC and firehose. Prior to this, a pure substreams chain couldn’t be synced.(#4839)

Bug fixes

• Fix for rewinding dynamic data source - Resolved an issue where a rewind would fail to properly remove dynamic data sources when using graphman rewind. This has been fixed to ensure correct behavior.(#4810)
• Improved Deployment Reliability with Retry Mechanism - A retry feature has been added to the block_pointer_from_number function to enhance the robustness of subgraph deployments. This resolves occasional failures encountered during deployment processes.(#4812)
• Fixed Cross-Shard Grafting Issue - Addressed a bug that prevented cross-shard grafting from starting, causing the copy operation to stall at 0% progress. This issue occurred when a new shard was added after the primary shard had already been configured. The fix ensures that foreign tables and schemas are correctly set up in new shards. For existing installations experiencing this issue, it can be resolved by running graphman database remap.(#4845)
• Fixed a Full-text search regression - Reverted a previous commit (ad1c6ea) that inadvertently limited the number of populated search indexes per entity.(#4808)
• Attestable Error for Nested Child Filters - Nested child filter queries now return an attestable ChildFilterNestingNotSupportedError, improving error reporting for users.(#4828)

Graphman

• Index on prefixed fields - The graphman index create command now correctly indexes prefixed fields of type String and Bytes for more query-efficient combined indexes. Note: For fields that are references to entities, the behavior may differ. The command may create an index using left(..) when it should index the column directly.
• Partial Indexing for Recent Blocks - The graphman index create command now includes a --after $recent_block flag for creating partial indexes focused on recent blocks. This enhances query performance similar to the effects of pruning. Queries using these partial indexes must include a specific clause for optimal performance.(#4830)

• ens_name_by_hash is now undeprecated: This reintroduces support for fetching ENS names by their hash, dependent on the availability of the underlying Rainbow Table (#4751).
• Deterministically failed subgraphs now return valid POIs for subsequent blocks after the block at which it failed. (#4774)
• eth-call logs now include block hash and block number: This enables easier debugging of eth-call issues. (#4718)
• Enabled support for substreams on already supported networks. (#4767)
• Add new GraphQL scalar type Int8. This new scalar type allows subgraph developers to represent 8-bit signed integers. (#4511)
