Hello, First off, is this the right list to post questions about MariaDB's source code? If it is not, I apologize, and can somebody please direct me to the right alias? I could not find anything on MariaDB's website. I have noticed the following behavior in MariaDB 5.1.47 with our storage engine that is different than MySQL. I see many cases where handler::start_bulk_insert before insertions, but handler::end_bulk_insert is NOT called. In MySQL 5.1.46, handler::end_bulk_insert is always called if there was a call to handler::start_bulk_insert. The commands run are: MariaDB [test]> create table ttt(a int); MariaDB [test]> insert into ttt values (1),(2),(3); Query OK, 3 rows affected (0.01 sec) Records: 3 Duplicates: 0 Warnings: 0 Is there a reason for this? Does some flag need to be exposed for this function to be called? Thanks -Zardosht
