Julian Hyde updated CALCITE-663:
--------------------------------
Description:
Add protocol version to Avatica protocol, to allow forwards and backwards
compatibility.
The first request should be a CreateConnectionRequest, let's add the attributes
there. I propose:
* CreateConnectionRequest.requestedProtocolType e.g. "json"
* CreateConnectionRequest.requestedProtocolVersion e.g. "1.2.0"
* CreateConnectionRequest.driverVersion
* CreateConnectionRequest.driverName e.g.
"org.apache.calcite.avatica.remote.Driver"
* CreateConnectionResponse.protocolType
* CreateConnectionResponse.protocolVersion
* CreateConnectionResponse.databaseVersion
There is currently no CreateConnectionRequest.
*Edit (Julian Hyde, 2015-10-24)*: No longer true. OpenConnectionRequest was
implemented in CALCITE-912.
Certain servers configurations would continue to allow connections to be
implicitly created, but using an explicit CreateConnectionRequest would always
be possible.
