> Might worth checking out TiCDC [deepwiki.com/pingcap/ticdc](https://deepwiki.com/pingcap/ticdc/) (e.g. EventStore uses PebbleDB which Go rewrite for RocksDB, so we can check whether it fits our ledger DB schema) @ivandika3 Thanks for the info! Looks like TiKV and TiCDC are designed to be disaggregated. TiCDC pulls the CDC stream from TiKV, reading either from the Raft log or the MVCC history in RocksDB. Then TiCDC sends changes to downstream sink. For Ozone, since we don't have builtin MVCC, we need to store the event into the ledger within the same key operation transaction in the same RocksDB. -- This is an automated message from the Apache Git Service.
