Talend giving Operation Timeout Exception while reading data from Cassandra

Anonymous — Tue, 09 Oct 2018 10:17:29 GMT

We are using Talend to process the data from Cassandra, we are facing operation timeout exception while reading the data from cassandra table. Please find below my environment details:

Talend version - 6.4.1 TOS

Cassandra - DataStax Community edition 3.8.0

Cassandra Driver - cassandra-driver-core-3.0.0.-shaded.jar

We have single node Cassandra vm as it is dev environment. Currently Cassandra holding 80 million records in one table, I am trying to execute below query while making connection to Cassandra using Talend:

select * from table where location = "xyz" and key = "some-date" allow filtering

(location and key both columns are not part of primary key)

Same query is working fine on cqlsh prompt and giving results within 20 seconds but while connecting from Talend it is throwing operation timeout exception.

I found in few communities that SocketOptions can be used to configure read time, but I am not able to set these properties in Talend. Please help me to configure these properties in Talend components.

Any other solutions are also appreciated.

Thanks in advance...
