planner: change predicateColumnCollector to columnStatsUsageCollector and collect histogram-needed columns #30671

xuyifangreeneyes · 2021-12-13T10:27:18Z

What problem does this PR solve?

Issue Number: close #xxx

Problem Summary:

What is changed and how it works?

Change predicateColumnCollector to columnStatsUsageCollector. It can collect both predicate columns and hist-needed columns in one pass.
Rename some functions in collect_column_stats_usage.go from (p *SomeLogicalPlan) xxx(c *columnStatsUsageCollector) to (c *columnStatsUsageCollector) xxx(p *SomeLogicalPlan).
Move the tests from planner/core_test to planner/core and use mock tables.

Should it be physicalTableID?

Seems physicalTableID is not set when it's non-partition table.
https://github.com/pingcap/tidb/pull/30754/files#diff-3b47fd3bf2c33ae3a03037a65ed39df33a4ae73debe9cf6f5bb2f397508061a0R4099

Yes, thinks for reminding. We can first check DataSource.isPartition. If it is true, use DataSource.physicalTableID. Otherwise use DataSource.TableInfo().ID.

I see, after #30754 is merged we can just use physicalTableID.

Fixed it and added test.

…eded-columns

… consider partition table

Can we use the constant flagXXXX instead of using 1<<13?

I move the tests from core_test to core and use flagXXX.

Some tests are updated because t2 only has two columns.

Can you add more comments about the special cases to explain this? It's not easy to understand why an expression.Column.UniqueID needs more table columns to calculate.

Can we merge this part? It seems the only difference is whether the expression is a slice or not.
Besides, we only need to export expression.ExtractColumnsAndCorColumnsFromExpressions, not all of them.

Please add more test cases for prepare statement, same to TestCollectHistNeededColumns.

Besides, add some test cases for subquery.

More tests about subquery have been added for both TestCollectPredicateColumns and TestCollectHistNeededColumns. In collect_column_stats_usage_test.go(in planner/core package) we cannot run tk.MustExec("prepare ...") because it is unit test and uses mock(For similar reason I don't test non-correlated scalar subquery here, which executes the subquery). Usually we have to run integration tests with tk.MustExec in planner/core_test package to avoid circle import. I will add integration tests to test prepare and non-correlated scalar subquery in #30816.

Is LogicalUnionAll here?

select count(*), sum(a), sum(c) from t has no LogicalUnionAll.

I mean lines 120-122

union is the same as union distinct, which eliminates duplicate elements. We use LogicalAggregation to implement it. So we don't have LogicalUnionAll here.

+func (s *testPlanSuite) TestCollectPredicateColumns(c *C) {


@xuyifangreeneyes why do you change the testing framework to pingcap/check? What's the necessity here?

The test uses the mocked tables, which are created in (*testPlanSuite).SetUpSuite in planner/core/logical_plan_test.go. So I change to the old testing framework.

You may give a review to #32597 where I migrate all planner tests to testfiy and cover your usage.

OK, I will take a look at it.
