>
> 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.
