-----------------------------------------
Summary: Sql. Resolve dependencies before query planning.
Key: IGNITE-20231
URL: https://issues.apache.org/jira/browse/IGNITE-20231
Project: Ignite
Issue Type: Improvement
Components: sql
Reporter: Andrey Mashenkov
As for now, we resolve dependencies after cutting a query plan into fragments.
After switching to Catalog, we will have no real tables/indexes available at
planning stage (just descriptors). Planner requires table statistics, which is
broken after switching to the Catalog.
Let's resolve all the dependencies before start planner to fix table statistics.
Also, ExecutableTableImpl instantiates ScannableTable and UpdatableTable
regardless if the table is used for scan or update. Let's make lazy
instantiation.
