Thomas D'Silva updated PHOENIX-5180:
------------------------------------
Description:
If we want to look up the PTable of a tenant view we currently need to create a
tenant specific connection and call {{PhoenixRuntime.getTable()}}. This could
be inefficient if we need to create millions of tenant specific connections.
We could instead just pass in the tenant id and use a global connection
{{getTable(Connection conn, String tenantId, String fullTableName, long
timestamp)}}
Insread of using the scn from the connection to set the clientTimestamp, we
would use the passed in timestamp.
If the table isn't cached we would need to make a rpc to fetch the table from
SYSTEM.CATALOG
{code:java}
MetaDataMutationResult result = new MetaDataClient(pconn).updateCache(PName
tenantId, String schemaName, String tableName)
{code}
