Cardano DB Sync 13.6.0.2

on GitHub

This release is compatible with node-10.1.2 and supports the Chang#2 HF in mainnet. It fixes an issue of 13.6.0.1 where rollbacks were too slow.

Upgrading from any 13.5.x.x db-sync instance requires a ledger state replay from genesis. This doesn't affect the database.

It is compatible with 13.6 and 13.5 snapshots. They can be found at:

Postgres setup

It is advised to use a postgres version >= 14. The default docker postgres has been upgraded to 14.10-alpine.
There is a postgres requirement for users that don't use docker-compose and have to manually configure postgres:

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

Notes

When running db-sync make sure you enable only the data that you need. This can be configured in the db-sync config file as documented here configuration.md
