rambo Commented on Running TPC-H Benchmark on AnalyticDB PostgreSQL

It's correct. There is no need to define a foreign key, index, etc., because it uses similar names in DDL for the columns that refer to the same value. For example, 'NATIONKEY' is configured as 'c_nationkey' in the CUSTOMER table and as 'n_nationkey' in the NATION table. Then when running the TPC query workload (DML), it uses a WHERE condition like 'WHERE c_nationkey = n_nationkey' to filter.

HrimfaxiYKW Commented on MySQL Deep Dive - Implementation and Acquisition Mechanism of Metadata Locking

Great article! Additionally, I have a question to ask the author. Will all the paths for acquiring `mdl` converge to `acquire_lock`? If so, does it mean that I only need to obtain all the `mdl_key` and their corresponding durations within one thread (`thd`), in order to construct an `mdl_request` in another MySQL process and fully replicate the `mdl` information?
