High level summary​

The db-sync team created a new tag 13.1.0.2 which is ready to release. We also investigated and had the first working UTxO-HD integration which is one of the potential future risks for db-sync.

Low level summary​

  • Integrated the UTxO-HD feauture branch in kderme/utxo-hd-1. This doesn't use the full on disk storage but keeps things in memory and the plan is to keep it this way for the first iteration. The integration still has some performance issues which we investigate
  • Created tag 13.1.0.2 which upgrades the dependencies of db-sync
  • Fixed an issue related to errors appearing in SMASH #1353
  • Continued with ghc-9.2 integration #1339
  • Worked on an new fixing procedure for #1348. We try to make these procedures work also on older schema version, without the need to migrate to newer schema, which can be very useful for fixing existing snapshots.

High level summary​

The DBSync team continued testing release 13.1.0.0. The QA team has reported that no issues have been found. The DBSync team also worked on cherry-picks back to master and on fixing bugs.

Lower level summary​

  • Release is cherry-picked back to master, which uses the new rollback mechanism which uses reverse indexes, same as the release #1320 This also fixes a bug number of issues on master.
  • Depenencies upgrade and CHaP integration #1324
  • AdaPots fix #1323. This fixes an issue where the per epoch AdaPots didn't match the epoch boundary, but they also included changes from the first block of the epoch.
  • Deposits Event fix #3212. This pr adjusts the Deposits ledger events, so that it can be better used by db-sync. This can reduce the number of queries that db-sync does during syncing an make syncing faster.
