> As per the docs KuduSession is not thread safe - https://kudu.apache.org/apidocs/org/apache/kudu/client/KuduSession.html
> This variable is a shared variable and instantiated at class level. I noticed there are multiple operations you do on top of KuduSession instance. These can possibly fail at concurrency. You may need to create new session per each these operations you do on top it in datastore methods or add some pooling mechanism from your code. Please check on this whether we have complication at concurrency.
