This release fixes an issue with restarts, similar to node version 9.1.1. It is compatible with node version 9.1.1.

It is recommended that all users upgrade to db-sync version 13.5.0.2 when restarting their db-sync instance. It is also recommended to delete all ledger snapshots before upgrading.

The release also fixes an issue with flag --disable-cache not working properly and makes replaying from genesis faster, since it reduces redundant snapshots.

Upgrading

Upgrading from any 13.4.x.x or 13.5.x.x db-sync instance requires a ledger state replay from genesis. This doesn't affect the database. This is the final release that will support upgrading from pre-HF 13.x versions.

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
