Slow Insert/Update in MariaDB Columnstore 1.0.3
My configuration is 2UM10PM with MariaDB Columnstore 1.0.3. I observed that the insert/update speed was very slow. I listed all processes in the system and found that many connections were trying to create temporary tables in infinidb_vtable. These queries occupied a lot of connections so that the system threw errors of "too many connections". Can you help investigate the problem? Thank you very much.
In addition, I will verify it in the MariaDB Columnstore 1.0.4 with configuration 2UM3PM. Please give me some ideas. Thanks.
