Centera connection pooling

Hi Sugu,

You might want to post this question in the Centera developer community -

Thanks,

You can download from the EDN Centera section our best practises but in summary we recommend that you only open one pool connection and then use that pool connection for all your IO threads.

Your application can have up to 20 IO threads per access node on the centera although remember this number is shared between all applications that may be using the centera cluster

Thanks Paul.  This means Centera SDK or XAM APIs do not create or maintain any pool of connections.. instead its application teams responsibilities to create 10 or whatever number of connections upfront, pool it, serve it and close it.  Is my understanding correct?

Any update on how long the connection will be open from Centra side.  Like once I open a connection, will it be alive till I close the connection or there will be some timout period associated with each connections.

Thanks in advance

under the covers the SDK will open up a number of socket connections which it will use when one of your threads does an IO.  The application creates the threads and typically uses that pool of threads to do IOs.  As your threads performs a write or read SDK operation the SDK will use an available socket to talk to the cluster.

The pool connection can be kept open for as long as your application is up.  There is no need to close and reopen.

I'm assuming your application will will access the Centera on behalf of your users regardless of the number of users.  In that case your application would open one pool/xsystem connection and your IO thread pool which satisfies user requests, would use that one connection.

Hi everyone,

Is there someone who knows where I can get the Centera SDK?

Thanks
