Notes

  • This release drops the officiall support for Ubuntu 18.04 and adds support for Ubuntu 22.04 (see #100)
  • This is the last version that uses beam-automigrate for managing the database schema, from this version on, we'll switch to managing the schema using incremental migration scripts (see #101, #102, #104). When future versions of chainweb-data need to migrate the database from a version earlier than 2.1.0, they will ask the user to first run 2.1.0 to prepare their database for incremental migrations.

New Features

  • A new /txs/account endpoint for fetching the incoming and outgoing transfers of a Kadena or non-Kadena account. #76 (also #83, #96, #103, #110, #114, #117, #124, #125)
  • All search endpoints (/txs/{account,events,search}) now support an optional (at the discretion of the HTTP gateway) "bounded execution" workflow (#109, also #118, #121)
  • The event search endpoint /txs/event now accepts 2 new arguments to narrow down the search results (#74):
    • modulename: Narrows down the search to events whose modules names match this value exactly
    • minheight: The minimum block height of the search window
  • A hidden new --serve-swagger-ui CLI argument that can be passed to chainweb-data to make it serve a Swagger UI for an auto-generated OpenAPI 3 spec for the chainweb-data HTTP API. The CLI argument is hidden because this spec is rudimentary and unofficial at the time of this release. Future releases will improve it.
  • A new --ignore-schema-diff CLI argument to chainweb-data to make it ignore any unexpected database schema changes. This can be used by chainweb-data operators to make schema changes to their database and keep running chainweb-data, but such ad-hoc database schema changes are not officially supported since they can cause a wide variety of errors under unpredictable conditions.
  • A new migrate command for the chainweb-data CLI that can be used to run the database migrations and exit.
  • A new /txs/txs endpoint similar to /txs/tx, but it returns a list of TxDetail objects, which can contain more than one entry when a transaction is introduced multiple times into the blockchain on independent branches. #71 #72

Performance improvements

  • Code search and event search query optimization (#67)
  • Add requestkey indexes on events and transactions tables (#98)
  • Refactor richlist generation (#89)
  • Load-based throttling for search endpoints (#116)
  • Optimize the recent transactions query at server start up (#119)
  • Set random_page_cost to 0 for CW-D connections #122

Bug fixes

  • Coin circulation calculation fix #97
