By increasing the size of the connection pool from the Sequel-default 4 to 16, we increase the parallelism of pipelines that are using this filter by four- fold, reducing the situations where a pipeline's total throughput is constrained by this plugin's connection pool to the internal Derby DB. We also increase the pool timeout from the Sequel-default 5 seconds to 30 seconds, so that failures to immediately acquire a connection don't result in failed lookups.

By increasing the size of the connection pool from the Sequel-default 4 to 16, we increase the max parallelism of pipelines that are using this filter by four- fold, reducing the situations where a pipeline's total throughput is constrained by this plugin's connection pool to the internal Derby DB.
We also increase the pool timeout from the Sequel-default 5 seconds to 30 seconds, so that failures to immediately acquire a connection don't result in failed lookups.
This issue is meant to mitigate the root-cause beneath #186 without expanding the scope of configuration options for the
jdbc_staticfilter, which would be a substantial effort.
