[jira] [Created] (CALCITE-1128) Support addBatch()/executeBatch() in remote driver

Josh Elser created CALCITE-1128:
-----------------------------------

             Summary: Support addBatch()/executeBatch() in remote driver
                 Key: CALCITE-1128
                 URL: https://issues.apache.org/jira/browse/CALCITE-1128
             Project: Calcite
          Issue Type: Improvement
          Components: avatica
            Reporter: Josh Elser
            Assignee: Josh Elser
            Priority: Critical
             Fix For: next


JDBC has some "batch-oriented" APIs which should help in the heavy-write workloads. These should help ammortize the RPC cost of repeated PrepareAndExecuteRequests and ExecuteRequests.

Through some of the recent performance work, CALCITE-1091, I think we're getting close to the limit of what is possible given our current server implementation (both in terms of HTTP-based clients and deserialization in POJOs). The thought is that we will get some better throughput if we reduce the total number of RPCs.
