+*Jdbc Integration - 5.6.1*
+
+* Fixes an issue where the `jdbc_static` filter's throughput was artificially limited to 4 concurrent queries, causing the plugin to become a bottleneck in pipelines with more than 4 workers. Each instance of the plugin is now limited to 16 concurrent queries, with increased timeouts to eliminate enrichment failures. https://github.com/logstash-plugins/logstash-integration-jdbc/pull/187[#187]
