Upgrade instructions

With this release, we continue our effort to provide easy upgrades from previous releases without the need to resync from genesis. During an upgrade from 13.x, db-sync will change the existing schema and update or fix some of the values that were inserted in the database from previous releases. Read the upgrading docs before upgrading for more details.

Changelog

https://github.com/input-output-hk/cardano-db-sync/blob/6e69a80797f2d68423b25ca7787e81533b367e42/cardano-db-sync/CHANGELOG.md#13112

Added

  • compatibility with Cardano node-8.0.0 and node-8.1.1
  • compatibility with the new format of the CostModel in the Alonzo genesis file
  • a procedure which fixes scripts with wrong cbor during upgrading
  • a procedure to fix ada_pots during upgrading
  • developmental ghc-9.2 compatibility
  • experimental options which turn off parts of the schema to reduce time, memory and storage requirements
  • experimental extra migrations which speed up UTxO queries. Read more consumed-tx-out and prune-tx-out.

Fixed

  • an issue where the ada_pots didn't match exactly the epoch boundary
  • an issue where epoch table didn't rollback
  • an issue with smash returning InvalidUrlException

Improved

  • Takes less snapshots, since big rollbacks are now faster
  • When --disable-ledger is enabled a --state-dir is no longer required

Known issues

  • The new extra migrations are only experimentally supported because they're not very well tested and there are a few known issues with them #1420
  • The epoch table may have some wrong values after upgrading from a previous release.

Notes

There is a postgres requirement for users that don't use docker-compose and have to manually configure postgres:

It is advised to increase the `maintenance_work_mem` from the Postgres configuration to 0.5GB - 1GB (default is 64MB).
Also use the default (2) or higher `max_parallel_maintenance_workers` (this parameter was introduced in `postgres` version 11)
