I tried to export 1 million row of my table and return:

runtime: out of memory: cannot allocate 1073741824-byte block (1576697856 in use)
fatal error: out of memory

how to use batch or something like that to reduce memory usage?

Are you using WriteString method?
As indicated in the comment it may require a lot of memory.
