Job Failure: tCassandraInput_1 Cassandra failure during read

badri1 — Sat, 16 Nov 2024 06:13:32 GMT

One of the job is failing.
Since we have more than 600GB per node and we have 17 nodes. So when we use "tCassandraInput_1" and provide a select query to fetch data to tMap it will throw an error as cassandra will not support select query for bigger Dataset.
Please let us know which component to use or how to resolve this issue.

Below is the debug logs:

Starting job ras_stream2batch_device_hourly_data at 14:28 28/03/2019.

Hi,

this is not a Talend specific issue, but issue related to Cassandra and could be repeated with any Cassandra client

the sample of discussions - https://stackoverflow.com/questions/32689856/cassandra-timeout-during-read-query-at-consistency-one

it better to ask on Cassandra related forums, how to better tune it

as a variant - increase the timeout in Cassandra settings, but not sure if it help on huge datasets with large returned numbers of rows
