- ragall 24d agoAre you one of the developers ? If so, you need to add a specific page explaining in detail the guarantees that this gives. For example: point 08 says "Assign different tables or workloads to different shard groups" and point 02 says "Split hot shards as workloads grow". How do those interact ? Can a single table be split across multiple shards ? If so don't you need 2pc to enforce primary key constraints ? The intro pages just read as AI slop.
- levkk 24d agoCurious to compare your implementation to ours [1] some day (if you guys open source it). [1]: https://docs.pgdog.dev/features/sharding/2pc/ https://docs.pgdog.dev/features/sharding/2pc/
