Cardano DB Sync 13.5.0.1

on GitHub

This release fixes an issue with restarts, similar to node version 9.1.1 fixes. It is compatible with 9.1.1.
It also fixes an issue with flag --disable-cache not working properly.

It is recommended that all users upgrade to db-sync version 13.5.0.1 when restarting their db-sync instance.

Upgrading

Upgrading from any 13.4.x.x 13.5.x.x release happens instantly.
Upgrading from other 13.x.x.x releases is also possible. A ledger state replay may be necessary from genesis. The existing db is not affected by this, only the ledger snapshot.

The release is compatible with 13.5, 13.4, 13.2 and 13.1 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
