We use XTDB 1 and have a multi replica production instance with about 600GB of data at ~100 million transactions. The biggest problem we have is with minor versions bumping the underlying RocksDB i dex version, requiring a full reindex of the main "golden" data store taking days to weeks.
AFAIK this is not solved in XTDB 1. I'm hoping XTDB 2 provides a better upgrade path for modestly sized databases like ours.
- refset 3y agoXTDB 2 will compute and maintain incremental indexes on-the-fly based on the raw data, so index updates will present far less operational impact. This also means the transaction log is now ~ephemeral in the new architecture (no more event-sourcing-style replays required, ever).
- kevinmershon 3y agoThat is incredibly exciting! Glad to hear it.
