I am use OrientDB OETL to extract data from postgresql. In some big query I have follow error in postgres:
Caused by: org.postgresql.util.PSQLException: ERROR: canceling statement due to conflict with recovery Detail: User query might have needed to see row versions that must be removed.
There is some way of use OETL to control this problem?
Obs: I cannot change configuration in origin postgresql database. It's not about my administration.
