Julian Hyde updated CALCITE-1262:
---------------------------------
Description: When scans of multiple JDBC tables with separate
{{JdbcConvention}} s are included in the same logical plan, {{VolcanoPlanner}}
only fires rules for one of the conventions. This results in only one of the
databases benefiting from optimizations and forces only
{{JdbcToEnumerableConverter}} over {{JdbcTableScan}} in the other. This seems
to be a result of static rule descriptions in all JDBC rules except
{{JdbcToEnumerableConverterRule}}. When JDBC rule descriptions are changed to
include the {{JdbcConvention}}, all rules are fired as expected. (was: When
scans of multiple JDBC tables with separate {{JdbcConvention}}s are included in
the same logical plan, {{VolcanoPlanner}} only fires rules for one of the
conventions. This results in only one of the databases benefiting from
optimizations and forces only {{JdbcToEnumerableConverter}} over
