ie starts from today:
https://github.com/ydb-platform/ydb-go-sdk/actions/workflows/tests.yml?query=event%3Aschedule

when runs switch to stable red.

same tests work fine with stable versions of YDB

workaround:

set

table_service_config:
  enable_oltp_sink: false

in ydbd config

Found bug. The problem is joining table with EmptyIterator, thus creating unused input (table). We should optimize unused inputs.

P.S. Bug can be reproduced without enabled sink
