Ivan Bessonov updated IGNITE-21205:
-----------------------------------
Description:
Current implementation blocks meta-storage watch thread until new schema
version is written into the meta-storage. This is an expensive IO operation,
and it might introduce unexpected turbulence.
Some scenarios greatly suffer from it. For example, we can't process lease
updates while we're writing into meta-storage, which shouldn't be the case.
was:TBD
> Don't store table versions in meta-storage in SchemaManager
