-------------------------------------------
Summary: Timeout handling in JDBCIO
Key: BEAM-5305
URL: https://issues.apache.org/jira/browse/BEAM-5305
Project: Beam
Issue Type: Bug
Components: io-java-jdbc
Affects Versions: 2.5.0
Reporter: Byambasuren Ganbaatar
Assignee: Jean-Baptiste Onofré
Hello, we have a batch pipeline that is reading data from Oracle, writing it to
BigQuery.
Using JdbcIO, BigQueryIO and Oracle driver [3].
We run this job 2 times in a day, the pipeline usually works fine, it completed
within 10 minutes.
But sometimes we have a [1] warning from this job, it never finished until we
cancelling it.
(sometimes means 4 times in last month)
Even we set timeout configuration for our code [2], warning log says [1]
Processing stuck in step Read JDBC.
Would you explain and correct us this kind of problem?
We already contacted Google Support Team, they said our configuration code is
looked fine them. Then they instructed us to ask here.
Thanks,
Bya
