- foobiekr 4y agoHence "the data persistence part."
- robertlagrant 4y agoThis sounds like a write-back / write-through cache with extra terminology. What's the difference?
- foobiekr 4y agoThe difference is the 10,000x slower performance if you move the actual DB transaction leader for the shard to over-the-wire access. Anything can be anywhere if we ignore latency and throughput.
