Cardano DB Sync 1.4.0

The Cardano DB Sync component (cardano-db-sync) synchronises chain data into a relational database.

Previously this component was released as part of the Cardano Explorer backend. In this release it has been renamed and moved into its own source repository, separate from the Explorer API.

It consists of the following components:

  • cardano-db library (renamed from cardano-explorer-db)
  • cardano-db-sync service (renamed from cardano-explorer-node)
  • cardano-db-sync-extended service (a variation of cardano-db-sync used by cardano-graphql)

This release with updated library dependencies follows the release of Cardano Explorer 1.3.0.

Compatible with Cardano node 1.8.0.

Deployed on 23th March 2020.

New features

  • Implemented a new plugin system to allow application-specific variations
  • Added new component cardano-db-sync-extended to support SQL DB backend for cardano-graphql

Improvements

  • Added extra "epoch" table with incrementally maintained view used by cardano-db-sync-extended
  • Improved chain sync behaviour when database is ahead of node
  • Used threaded RTS to avoid potential IPC problems on OSX
  • Improved exception handling and reporting
  • Improved default logging verbosity configuration
  • Improved documentation

Resolved issues

  • cardano-db-sync cannot connect to cardano-node (#9)
  • Enable logging for production (#7)

Known Issues

  • Some build instructions have not updated with new configuration file names (#32)
