> Issue Type: Bug
> Components: camel-sql
> Affects Versions: 4.14.5
> Reporter: Roman Stechkevych
> Assignee: Federico Mariani
> Priority: Major
> Fix For: 4.14.6, 4.18.2, 4.19.0

>
> Issue occurs when JDBC-based idempotent repository is used by multiple
> applications (instances), which are processing concurrently big number of
> files, for example.
> In my particular use case readLock=idempotent is configured for Camel File
> component endpoint. As a result, read lock can be acquired by two instances
> at the same time, which leads to unwanted simultaneous file processing.
> Issue is reproducible during concurrency test with 200 files being processed
> by two instances of the same application using JDBC-based idempotent
> repository.
> After corresponding fix (please find in attachments), issue has been resolved.
