How can I interpret the thread state? or What are different state of thread in SAP HANA database ?

 In SAP HANA, threads can be in various states, each indicating a different stage of their lifecycle or activity type. Understanding these thread states is crucial for diagnosing performance issues and optimizing system performance. 

Here are the different thread states in SAP HANA:

Thread state	Area	Details
Barrier Wait	Lock	Barrier wait
ConditionalVariable Wait	Lock	Mainly record and table lock waits, but also some internal locks
ConditionalVar Wait
ExclusiveLock Enter	Lock	Exclusive read / write lock waits
Futex Wait	Lock	Futex lock wait
Inactive	Idle	Idle thread
IntentLock Enter	Lock	Intentional read / write lock waits
IO Wait	I/O	Disk I/O wait (e.g. during column load or hybrid LOB access)
Job Exec Waiting	Idle	Waiting for a JobWorker thread executing the actual work
Joining	Idle	Joining of execution context of another thread, i.e. waiting for the termination of the other thread
Mutex Wait	Lock	Mutex lock waits
Network Connect	Network	Network I/O between SAP HANA nodes or services, timeouts can be configured with client properties like connectTimeout and nodeConnectTimeout (SAP Note 2186744)
Network Poll	Network	Network I/O between SAP HANA nodes or services
Network Read	Network	Network I/O read between SAP HANA nodes or services
Network Write	Network	Network I/O write between SAP HANA nodes or services
Resource Load Wait	I/O	Disk I/O wait (e.g. during undo file load, DataAccess::UndoFileAnchor::allocateFile)
Running	SQL	Request execution, typically CPU consumption
Semaphore Wait	Lock	Semaphore lock waits
SharedLock Enter	Lock	Shared read / write lock waits
Sleeping	Lock	Waiting for a lock
Speculative Lock Retry backoff	Lock	Transactional memory lock (back-off waiting on transaction retry)
Speculative Lock Wait for fallback	Lock	Transactional memory lock state (waiting on fallback lock)
TimestampLatch Wait	Lock	Waiting for a timestamp latch
3rd party Thread	Unknown	State of Native threads created outside of the standard SAP HANA context can't be determined and so they are displayed as '3rd party Thread' (SAP HANA >= 2.00.059.06, >= 2.00.065).
