* SQL INSERT planner support. The main changes are: 1) DruidPlanner is able to validate and authorize INSERT queries. They require WRITE permission on the target datasource. 2) QueryMaker is now an interface, and there is a QueryMakerFactory that creates instances of it. There is only one production implementation of each (NativeQueryMaker and NativeQueryMakerFactory), which together behave the same way as the former QueryMaker class. But this opens the door to executing queries in ways other than the Druid query stack, and is used by unit tests (CalciteInsertDmlTest) to test the INSERT planning functionality. 3) Adds an EXTERN table macro that allows references external data using InputSource and InputFormat from Druid's batch ingestion API. This is not exposed in production yet, but is used by unit tests. 4) Adds a QueryFeature concept that enables the planner to change its behavior slightly depending on the capabilities of the execution system. 5) Adds an "AuthorizableOperator" concept that enables SqlOperators to require additional permissions. This is used by the EXTERN table macro. Related odds and ends: - Add equals, hashCode, toString methods to InlineInputSource. Aids in the "from external" tests in CalciteInsertDmlTest. - Add JSON-serializability to RowSignature. - Move the SQL string inside PlannerContext so it is "baked into" the planner when the planner is created. Cleans up the code a bit, since in practice, the same query is passed in every time to the same planner anyway. * Fix up calls to CalciteTests.createMockQueryLifecycleFactory. * Fix checkstyle issues. * Adjustments for CI. * Adjust DruidAvaticaHandlerTest for stricter test authorizations. |
