[enhancement](nereids) improve lots of values in
insert into values…
… statement (#40202) improve lots of values in `insert into values` statement by bypass NereidsPlanner the main logic is 1. `InsertUtils.normalizePlan` use `FoldConstantRuleOnFE` to reduce the expression, e.g. `values(date(now())` 2. `FastInsertIntoValuesPlanner` skip most of rules to analyze and rewrite `LogicalInlineTable` to `LogicalUnion` or `LogicalOneRowRelation` 3. fast parse date time string without date format 4. getHintMap and normal lexer share the same tokens 5. `set enable_fast_analyze_into_values=false` can force to execute all optimize rules, when we meet some bugs in `FastInsertIntoValuesPlanner` test: insert 1000 rows with 1000 columns, the columns contains int, bigint, decimal(26,7), date, datetime, varchar(10 chinese chars) +---------------------------------+------------------------------------------------------+--------------------------+--------------------------+ |FastInsertIntoValuesPlanner |NereidsPlanner(enable_fast_analyze_into_values=false) |Legacy optimizer in 2.1.6 | Nereids planner in 2.1.6 | +---------------------------------+------------------------------------------------------+--------------------------+--------------------------+ |16s(bottleneck is antlr's lexer) |32s |16s |80s | +---------------------------------+------------------------------------------------------+--------------------------+--------------------------+ If you use FastInsertIntoValuesPlanner with group commit in a transaction, the time can reduce to 12s. TODO: build a custom lexer. in my hand write lexer test, FastInsertIntoValuesPlanner without group commit can reduce 16s to 12s, but it will take more effort: RegularExpression -> NFA -> DFA -> minimal DFA -> Lexer codegen
