[Maria-discuss] A general question about performance of update command

Hi there, I'm new to MariaDB and I'm running tests on the update command. Server version 10.5.11. I'm finding that updates to a table with engine=columnstore are far slower than to a table with default engine=innodb. Obviously, there is no primary key in a table with engine=columnstore, whereas the innodb table does have a primary key. In my tests, for engine=columnstore, 10000 rows took 1995 seconds to be updated, but for engine=innodb, 10000 rows took only 7 seconds to transfer. The difference suggests columnstore takes about 285X longer than innodb. Is this to be expected? I don't need a lengthy answer, btw, just general guidance. Thanks very much, Rob
