From 5d0d6380d0dd0787aaa4e1bcb379eb4aa8c87f04 Mon Sep 17 00:00:00 2001 From: aceforeverd Date: Wed, 15 Nov 2023 15:02:37 +0800 Subject: [PATCH] feat: left join (#3576) * refactor: iterator & table handler * refactor(runner): modulize runner.cc runner.cc is too large, sepreate RunnerBuilder, RunnerContext, Runner and ClusterTask in difference files * feat(sql): support left join * chore: refactor runner name & improve tests * fix(runner): build cluster request join runner For REQUESTJOIN(ANY1(T1), ANY2(T2)), ANY1 may optimize T1, REQUESTJOIN, ANY2 may optimize T2, building cluster task correctly --- cases/plan/join_query.yaml | 71 +- cases/query/fail_query.yaml | 21 + cases/query/left_join.yml | 575 +++++++++ .../toydb/src/storage/table_iterator.cc | 4 +-
