Revision history for cardano-db-sync

13.3.0.0

  • Support for Conway (see schema docs)
  • Fixed epoch_param missing for the first Shelley era [#1715]
  • Moved command line options that filter data to the config file
  • Added epoch_state table
  • Added an optional feature to store CBOR serialized transactions in tx_cbor table [#1723]

13.2.0.2

  • Support node 8.9.x
  • Add a new db-sync config field EnableFutureGenesis. When false or missing, the conway genesis file is ignored

13.2.0.1

  • Added a new table epoch_stake_progress which indicates when epoch_stake is completed
  • Uses the cache for the computation of epoch table when following
  • epoch_stake is now computed earlier, before the epoch is reached
  • Exception handling and concurrency improved.
  • When --disable-ledger is used, db-sync won't populate the tx.deposit field as it's too expensive
  • Support for Conway (see schema docs)
  • Added a --bootstrap-tx-out flag. Read more at doc/configuration.md.
  • When --consumed-tx-out is enabled, db-sync won't populate the tx_in table
  • Added flags --force-tx-in which bypasses the default behaviour mentioned above
  • Migrations from consume to prune are now much faster
  • References to offline for pool metadata are replaced by offchain
  • Added a new table extra_migrations
  • DBSync no longer does any query to the tx_out table during syncing
  • Added flags --disable-in-out, --disable-shelley, --disable-gov, --only-gov, --keep-tx-metadata
  • Move MIR from reward to instant_reward. Done with a migration.
  • Remove redundant field address_raw of tx_out and collateral_tx_out
  • Partial Conway integration. You can read more in doc/schema.md (tagged as Conway). Also in files schema/cardano-chain-gen/schema/migration-2-0032-20230815.sql and schema/cardano-chain-gen/schema/migration-2-0032-20230815.sql for the raw sql migrations.
  • Removed reward.id field. instant_reward table also doesn't have an id field.

13.1.1.3

  • Added experimental flags skip-plutus-data-fix, only-plutus-data-fix, force-indexes to cardano-db-sync
  • Added experimental flags force-indexes, mock-fix for cardano-db-tool run-migrations command
