Spikes seen in Source Transformer when auto scaling #859

Closed RohanAshar closed 3 months ago

RohanAshar commented 1 year ago

Describe the bug During stead traffic we see there are spikes in the source transformer read messages when auto scaling is enabled. The following behavior was observed with min and max set to 1 and 5 respectively. The issue resolved itself when both the min and max were set to 5.

Expected behavior The read messages should follow the same behavior irrespective of auto scaling.

Please try out 0.9.0-rc2, which includes #846, which should alleviate this issue.

RohanAshar commented 1 year ago

Upgrading to 0.9.0-rc2 did not work. It still has the same behavior.
