Peter Vary commented on HIVE-21637:
-----------------------------------
Hi [~daijy]!
Nice work! Just learning ACID, but until now I had the impression that only DML
operations will create new transactions/writeIds. Your doc indicates that DDL
operations will create new writeIds too. Could you please confirm? Do we have
transactions for every operation now?
Thanks,
Peter

> Currently, HMS has a cache implemented by CachedStore. The cache is
> asynchronized and in HMS HA setting, we can only get eventual consistency. In
> this Jira, we try to make it synchronized.
