Subject Re: XML vs mysql import with DataImportHandler
Date Mon, 03 Nov 2008 15:47:31 GMT

Hi Shalin,
I would like to know if you just used batchsize = -1.
When I do that I use all Mysql's memory and it's a problem for the database
and other process on it like update insert ... 
It will keep my database busy for 10hours, it's too much, is there a way to
manage it differently ? 

Thanks a lot,
