Problem
Recent changes in YugabyteDB introduced some changes where the
relcache/catcacheis reloaded as soon asyb_read_timeis set. Now that caused an issue with the snapshots in the connector i.e. whenever the connector sets theyb_read_timeand goes on to take the snapshot by running aSELECT *query, it gets the following error:Solution
As a workaround, we will now bypass the catalog version check by setting a GUC
yb_disable_catalog_version_checkat the connection level so that we do not hit the error during snapshot.Note that we do not require this during streaming phase and since streaming used a separate object of
ReplicationConnectionclass, we will not be modifying it.This closes yugabyte/yugabyte-db#25716
