Spring Boot currently requires Java 17 as a minimum. Upgrading the Aerospike Java client to a jdk21 version would break this compatibility. We plan to adopt the jdk21 client once Spring Boot no longer supports Java 17. Did your performance tests indicate a significant improvement between the jdk8 and jdk21 Aerospike clients?

Did your performance tests indicate a significant improvement between the jdk8 and jdk21 Aerospike clients?

yes, this test was performed local(macOS m1) so it may not be accurate, but performance of aerospike-client-jdk8 vs. aerospike-client-jdk21 is more than double different across all metrics
