[dawidmalina]

It would be.nice to have dedicated profiler for cassandra same as we have for redis.

Is there any updates for this?

I found this: https://github.com/dynaTrace/Dynatrace-Apache-Cassandra-Fastpack

Based on this I've created a list with classes and methods that (probably) should be traced. I hope it will help.

Class Name	Method Name
org.apache.cassandra.service.AbstractWriteResponseHandler	get
org.apache.cassandra.thrift.CassandraServer	getSlice, state
org.apache.cassandra.db.compaction.CompactionManager	doCompaction
org.apache.cassandra.thrift.Cassandra$Processor$ProcessFunction	process
org.apache.cassandra.thrift.Cassandra$Processor	process
org.apache.cassandra.service.StorageProxy	mutate, performWrite, insertLocal, mutateCounter, applyCounterMutationOnLeader, applyCounterMutationOnCoordinator, read, scan
org.apache.cassandra.db.compaction.CompactionTask	execute
org.apache.cassandra.db.compaction.CompactionManager$CompactionExecutorStatsCollector	beginCompaction
me.prettyprint.cassandra.model.ExecutingKeyspace	doExecute
org.apache.cassandra.thrift.Cassandra$Iface	get, get_slice, get_count, multiget_slice, multiget_count, get_range_slices, get_indexed_slices, insert, remove, remove_counter, batch_mutate
com.datastax.tutorial.InsertRowsForColumnFamilies$ExecTask	run

For what it's worth, the Thrift generated classes (at least the client side) should already be handled by the Thrift plugin

org.apache.cassandra.thrift.Cassandra$Iface (client)
org.apache.cassandra.thrift.Cassandra$Processor$ProcessFunction (server)
org.apache.cassandra.thrift.Cassandra$Processor (server)

A proper Cassandra support would be the way to go eventually, and this should be in the works (not 100% sure on this)

This also should be helpful : https://github.com/spring-projects/spring-insight-plugins/tree/master/collection-plugins/cassandra
