I recently came across CockroachDB[0] which is a distributed SQL
database. Operationally, it is easy to run and adding a new node to the
cluster is really simple as well. I believe it is targeted towards OLTP
workloads.

Hi all,
I am cross posting this from the Calcite mailing list, since the phoenix
query server uses Avatica from the Calcite project.
Go 1.8 was released recently and the database/sql package saw a lot of
new features. I just tagged the v1.3.0 release for the Go Avatica
driver[0] which ships
P.S. I meant to say normalizing rather than de-normalizing.

Hey,
You mentioned that you sent a PrepareAndExecuteRequest. However, to do
that, you would need to first:
1. Open a connection:
https://calcite.apache.org/docs/avatica_json_reference.html#openconnectionrequest
2. Create a statement:
https://calcite.apache.org/docs/avatica_json_reference.html#
Glad you got it working! :)
