…#47608) This pr can speedup huge InPredicate for partition pruning, for this sql: ```sql select * from tbl where dt in ('2024-01-02 01:00:00', ... , '2024-05-02 02:00:00') -- about 2k literals ``` In my test case, use 2k literals query the table with 20k hour (range / list) partitions, this pr can speed up from 12s to 160ms, if disable binary search filtering, and speed up from 6s to 160ms if enable binary search filtering The changes: 1. add `SessionVariable.enable_binary_search_filtering_partitions` to disable binary search filtering partitions 2. cache the Set/RangeSet of the `InPredicate.options`, instead of foreach options to evaluate it for every partition 3. use big RangeSet to intersect small RangeSet, the order is not trivial, because the TreeRangeSet is red-black tree, the right side need to foreach all items, and the left side can search fast 4. skip prune tablets if the number of InPredicate.options > `Config.max_distribution_pruner_recursion_depth`, because it tend to hit all buckets (cherry picked from commit 5ec7d34)
