Airbyte sync requiring multiple attempts after upgrade to 0.63.3


After upgrading to version 0.63.3, Airbyte syncs are failing and requiring multiple attempts on various sources like MySQL, PostgreSQL, Stripe API, and Shopify. Errors indicate issues with the destination process still being alive and stream closures. Upgrades to 0.63.4 and 0.63.5 did not resolve the issue. Snowflake connector version 3.11.0 is being used.


Since upgrade to 0.63.3 I’m experiencing that Airbyte needs multiple attempts before successful sync. It’s happening on multiple sources (mysql, postgres, stripe api, shopify) without any clear pattern. Usually somewhere between 3rd to 6th attempt it successfully finishes, but this increases the sync times significantly (i.e. for a sync that usually took ~10 minutes it now needs 6x10min because of retries).

The situation did not improve with upgrade to 0.63.4 / 0.63.5

I’m seeing errors like this:

java.lang.IllegalStateException: Destination process is still alive, cannot retrieve exit value.

Destination is Snowflake, I’m using latest snowflake connector 3.11.0

Anyone else experienced something similar? I’m not even sure where to start looking for a problem so any hint is more than welcome.

Hi Gasper, we’re on 0.63.1, and are also noticing that our syncs are taking longer/taking more retries and feeling confused. We’re syncing from eg. mysql, postgres, stripe, zendesk; destination is bigquery (2.6.0, not the latest version though)

Hi again, we increased MAX_SPEC_WORKERS, MAX_SYNC_WORKERS and worker.replicaCount as described|here (even though we use the OSS version) in our dev environment and in our case, we see improvements. I guess it’s addressing the symptom rather than the cause, but thought I’d share just in case it’d be relevant for you too :slightly_smiling_face:

<@U06MYV00TKQ> did i saw your message yesterday, that you was trying to change Cocurent Sync limit parameters, as described here

yes, it made things better in dev on some test syncs (we could reproduce and resolve the kinds of errors we were getting in prod). But once we rolled it out in prod, we still had some issues. So I thought maybe I shared that too early… will definitely update if we find something that works for us

i’m just testing change from 5 -> 10 on all workers (listed below), together with Airbyte upgrade to the latest release 0.63.6 but unfortunately it doesn’t seem to have any effect on the situation.

would it be possible to maybe try rolling back to an older version instead…? Our team decided to adjust the cluster autoscaling on top of the airbyte workers configurations and live with restarting some syncs for now… but I see things that suggest something’s wrong with the Airbyte instance itself. eg. a couple of syncs running with no related sync-specific pods or vice versa a sync failing but the three orchestrator/read/write pods remain for hours longer

sorry to bother you <@U01MMSDJGC9>, but have you heard of similar repeated failed sync attempt issues from people who upgraded to Airbyte 0.63.X…?
