> 1) org.apache.calcite.schema.impl.ListTransientTable#scan adds itself to a
> schema: root.getRootSchema().add(name, this); however, it misses cleanup, so
> it looks like a memory leak
> 2) ListTransientTable is not implementable with EnumerableTableScan as
> org.apache.calcite.tools.RelBuilder#transientScan(java.lang.String,
> org.apache.calcite.rel.type.RelDataType) is using
> org.apache.calcite.prepare.RelOptTableImpl#create(org.apache.calcite.plan.RelOptSchema,
> org.apache.calcite.rel.type.RelDataType, org.apache.calcite.schema.Table,
> com.google.common.collect.ImmutableList<java.lang.String>) which creates
> RelOptTableImpl with NULL expressionFunction which means
> org.apache.calcite.prepare.RelOptTableImpl#getExpression returns null
