-----------------------------------
Summary: Support cancel in remote JDBC driver
Key: CALCITE-520
URL: https://issues.apache.org/jira/browse/CALCITE-520
Project: Calcite
Issue Type: Bug
Reporter: Julian Hyde
Assignee: Julian Hyde
Remote JDBC driver should support canceling running statements.
I believe we have the ingredients already. The client knows the statement id of
a statement before it executes it. And when cancel is received in the client
JDBC driver, it can send a (new) CancelStatement request on a separate RPC
call. The server can then set the cancel flag, and from that point, the
mechanism is the same as local cancel.
