WL#1453: LOAD DATA INFILE load options
Affects: Server-7.1 — Status: Un-Assigned
We shall add the following options for LOAD DATA INFILE for more fine gain control of what is happening 1) CONCURRENT - This shall use concurrent insert to load data to the table, to allow SELECTS running at the same time on MYISAM table. It shall possibly imply SQL_CONCURRENT option once it is implemented to allow concurrent load of data in table with holes. 2) CHUNK=N - This is to allow loading data in "chunks" Once chunk is completed the tables shall be unlocked and locked once again. For MyISAM this will be useful to allow update queries to run for Innodb tables this will allow to avoid huge undo log generated, making things potentially recovery unsafe in case of MySQL crashes during load data infile.
