NDB Cluster: MaxNoOfConcurrentTransactions (1 reply)

Hello

I spinned out a NDB Cluster (2 Data Node, 2 Server Nodes, 1 Management Node - all are 16cpu machines). I did a load test on it for 1000 users. It worked great. However when I increased the load to 2000 users, it gives me the error: "Out of connection objects: increase MaxNoOfConcurrentTransactions".

I added the following lines to the [NDBD Default] of the config.ini file:
MaxNoOfConcurrentOperations=2000000
MaxNoOfConcurrentTransactions=2000000

After restarting the cluster, I run into the same error "Out of connection objects: increase MaxNoOfConcurrentTransactions" for 2000 users.

What could I be missing? Is the NDB cluster getting updated with my new changes? How do I verify?

Thanks!

P.S: I would eventually like to test for 100000 users
