[druid-user] Query Timeout

Hi All,

We have 3 different Druid cluster.
1 query which is successfully giving result all time from 2 out of 3 Druid cluster but sometimes from 1 Druid cluster query getting timed out
Error Message:
Query Timeout
Cannot acquire enough memory buffers
Org.Apache.druid.query.QueryTimeoutException.

Thanks,
Pathik

What kind of a query(type) is this?

Hi,

Extracting data from data source using time range last 20 hrs and also using inner join.

Thanks,
Pathik

Hi ,

Anyone can help on this?

Thanks,
Pathik

Did you copy-paste the error? It’s “memory buffers”, not “merge buffers”? I’ve seen the error about merge buffers, which would relate to the join, but not the “memory buffers” error.

Hi ,

I am getting below error message

Error Message:
Query Timeout
Cannot acquire enough memory buffers
Org.Apache.druid.query.QueryTimeoutException.

I can’t find that error in the code or anywhere. Is there more in any of your logs - eg, broker or historical?

Hi,

Even when I am running that query from Druid UI , then also I am getting error. Not related any query submissions from backend code.

Thanks,
Pathik

Is there more info in broker or historical logs? Maybe a full stack trace or something?

Hi,

I will try to capture more information from broker and historical logs and let you know.
Thanks,
Pathik
