Yinzuo Jiang 3628593d20 feat: Implement custom function module in milvus expr (#36560) ... OSPP 2024 project: https://summer-ospp.ac.cn/org/prodetail/247410235?list=org&navpage=org Solutions: - parser (planparserv2) - add CallExpr in planparserv2/Plan.g4 - update parser_visitor and show_visitor - grpc protobuf - add CallExpr in plan.proto - execution (`core/src/exec`) - add `CallExpr` `ValueExpr` and `ColumnExpr` (both logical and physical) for function call and function parameters - function factory (`core/src/exec/expression/function`) - create a global hashmap when starting milvus (see server.go) - the global hashmap stores function signatures and their function pointers, the CallExpr in execution engine can get the function pointer by function signature. - custom functions - empty(string) - starts_with(string, string) - add cpp/go unittests and E2E tests closes: #36559 Signed-off-by: Yinzuo Jiang <jiangyinzuo@foxmail.com>		2024-10-25 15:25:30 +08:00
