Latency in Logstream task

suvbin — Wed, 21 Aug 2024 04:22:42 GMT

Hi ,

We could see latency in the logstream task after some change activity at the source side. more redo logs got generated. Now the task is running behind of 100 to 200 logs. How to make replicate to read faster these redo logs.?

And also i could see around 24 transactions are not committed at source.

Please suggest.

readahead blocks has been set to 400000

Hello @suvbin

You need to check whether there is any long running transaction at the Oracle side which is not committed yet.

Replicate will be waiting for the source for the transaction to gets commit so latency will increase. Once transactions get committed, it will transfer the data to the target accordingly.
