Hello
I was using parseLdifFile to parse my LDIF file.
When the LDIF size is small, then it is okay.
But if the LDIF file size is 500M, with 1 million entries.. then it runs
out of memory
even I assign 6G memory to java heap
Can you please tell me if I just don't give them enough memory (how much)
or
this library does not support large LDIF size (can you please point me out
what library I should use) ?
LdifReader reader = new LdifReader();
List<LdifEntry> entries = reader.parseLdifFile("/home/myname/export.ldif");
It is the hash map throwing the out of memory exception.
*Attached the exception*
