• Self Observability: add metrics_aggregation_queue_used_percentage and metrics_persistent_collection_cached_size metrics for the OAP server.
• Optimize metrics aggregate/persistent worker: separate OAL and MAL workers and consume pools. The dataflow signal drives the new MAL consumer, the following table shows the pool size, driven mode and queue size for each worker.

Worker	poolSize	isSignalDrivenMode	queueChannelSize	queueBufferSize
MetricsAggregateOALWorker	Math.ceil(availableProcessors * 2 * 1.5)	false	2	10000
MetricsAggregateMALWorker	availableProcessors * 2 / 8, at least 1	true	1	1000
MetricsPersistentMinOALWorker	availableProcessors * 2 / 8, at least 1	false	1	2000
MetricsPersistentMinMALWorker	availableProcessors * 2 / 16, at least 1	true	1	1000

• Bump up netty to 4.2.4.Final.
• Bump up commons-lang to 3.18.0.
• BanyanDB: support group replicas and user/password for basic authentication.
• BanyanDB: fix Zipkin query missing tag QUERY.
• Fix IllegalArgumentException: Incorrect number of labels, tags in the LogReportServiceHTTPHandler and LogReportServiceGrpcHandler inconsistent with LogHandler.
• BanyanDB: fix Zipkin query by annotationQuery
• HTTP Server: Use the default shared thread pool rather than creating a new event loop thread pool for each server. Remove the MAX_THREADS from each server config.
• Optimize all Armeria HTTP Server(s) to share the CommonPools for the whole JVM. In the CommonPools, the max threads for EventLoopGroup is processor * 2, and for BlockingTaskExecutor is 200 and can be recycled if over the keepAliveTimeMillis (60000L by default). Here is a summary of the thread dump without UI query in a simple Kind env deployed by SkyWalking showcase:
