> The JDBC Idempotent Repository does a full transactional query on every check by the Idempotent Consumer.  On SQL Server implementations that have a high overhead per query, each query can take two seconds. For a 1000 checks, this can take a half hour.  My proposal is to cache the repository list in a single query and then reference that list in memory.
