I have the vast data in mysql about (1.5G)
I got some data from machine and want to search some field
that does not exist in mysql. i just want to insert these data that
does not exist in mysql before.
I use hash to handle these data.
First i load data into hash from mysql and search data if it is exist.
but i use the vast memory at the same time
how to solve this program??
if i insert all data by setup db field data is unique. this will spend a lot
of time.
give me some suggest!!
ps:the data is more than 500M one time insert process
