Overview :

With previous versions we were able to register 10k cmhandles (in 4 threads) in 12 minutes.
With the current CPS master we sent the 10k cmHandles around 10 minutes to NCMP, so it is not faster than before. What I see is that NCMP starts getting modules in a background thread (seems to be one thread) and handling one cmhandle takes more seconds.
Currenlty in 12 minutes only 150 cmHandles got available with ready state in NCMP, because getting modules and changing the state is quite slow this way.

...

Analyzed the logs the summary is as below :

Patch used for testing :

https://gerrit.onap.org/r/c/cps/+/129829/5//COMMIT_MSG

...

Local Development Machine with CSIT docker deployment (with dmi-plugin that is implemented by CPS team)

Note : dmi-plugin is able to handle only 5-8 cm handle per seconds concurrently.

Scenario 1: If there is no cm handle into Advised state

Problem Statement

With previous versions we were able to register 10k cmhandles (in 4 threads) in 12 minutes.
With the current CPS master we sent the 10k cmHandles around 10 minutes to NCMP, so it is not faster than before. What I see is that NCMP starts getting modules in a background thread (seems to be one thread) and handling one cmhandle takes more seconds.
Currently in 12 minutes only 150 cmHandles got available with ready state in NCMP, because getting modules and changing the state is quite slow this way.

Expectation/ goal: cm-handle registration + module sync → 25 cm handles / sec (see CPS Interface Performance Requirements Overview)

Introduced timeout for connect and reading for RestTemplate while connecting dmi-plugin. 2. Modified data structure of moduleSyncSemaphore to hold YangModelCmHandle referance (cm handle id) as key of map 3. Working of Modulewatchdog is modified with parallelism and broken into async tasks. 4. ModuleSyncSemaphoreMap is now populated with advised cm handles and processed by Modulewatchdog by batch size (Dynamic batch size at cm registration). 5. Introduled parallelism level for async tasks that are suppiled. 6. Includes cm handle registration preformance code change. 7. Performance Improvement: Postgres Pool Configuration 8. Performance Improvement: Async Notification Pool Configuration. 9. Performance Improvement: Save/update batch of CM-Handle States in one operation. 10. Performance Improvement: Updating (many) child datanodes/datanode tree into one SQL operation 11. Performance Improvement: Native query to more efficiently get all yangResourceIds. 12. Performance Improvement: Detaching fragment entities early. 13. Performance Improvement: Decouple Temporal DB Notification from main thread.

Note : It includes bottleneck of in recursive method (org.onap.cps.spi.impl.CpsDataPersistenceServiceImpl#toDataNode)Joe K is working on it to improve. 2. dmi-plugin is able to handle only 5-8 cm handle per seconds concurrently.
