Logstash information:

docker image
bitnami/logstash:7.10.1-debian-10-r35

JVM (e.g. java -version):

N/A

OS version (uname -a if on a Unix-like system):

N/A

Description of the problem including expected versus actual behavior:

When using jdbc_static to fetch a reasonable list of records from MySQL database, the pipeline is blocked while recrods get fetched. This causes peak CPU usage as schedule intervale.

I would expect the pipeline to be blocked only during the derby database refresh. Not during the fetching.

Provide logs (if relevant):

When the following line of code get printed, the pipeline stop processing.

[2021-11-02T15:44:48,867][INFO ][logstash.filters.jdbc.readwritedatabase][main] loader inventory, fetched 54114 records in: 79.353 seconds
[2021-11-02T15:44:50,897][INFO ][logstash.filters.jdbc.readwritedatabase][main] loader inventory, saved fetched records to import file in: 2.028 seconds

   Locked ownable synchronizers:
        - locked <504ac9f5> (a java.util.concurrent.locks.ReentrantReadWriteLock$FairSync)

The problem seams to be related to Line 66: https://github.com/logstash-plugins/logstash-integration-jdbc/blob/master/lib/logstash/filters/jdbc/read_write_database.rb#L66

The write lock is aquired to early in the process. It should be aquired after fetching the records on Line 72
