[accumulator] com.stitchdata.target-stitch-avro.accumulator-thread - accumulator thread is dying - Java heap space

Has anyone encountered this error?

We are using the Google Cloud SQL PostgreSQL Integration writing to Snowflake as the destination. It is able to load some rows every now and then but keeps giving this error on each extraction run.

Hello @preston-settle
Is this a local connection you’re running? As far as we know, our production memory limit is 6G.
You can probably tweak some advanced options, like itersize.

We have two non-customer-facing settings we can help to set. Those are the Incremental limit and the Itersize values.
