error: java.lang.outofmemoryerror: gc overhead limit exceeded

You should set Auto Commit
property to false
when executing queries for big PostgreSQL
tables because the driver does not honor fetchSize
while auto commit set true(default)
Unfortunately , sql executors
in current Nifi
versions do not have that property.
