[Koha] Stage MARC Records For Import

[Jared Camins-Esakov]

Vitor,

The operation is very slow, and, in my experience, breaks when you try to
import more than about 20MB worth of records through the web interface. I
understand this has something to do with network conditions, so it's not a
hard limit. The best way to import large amounts of data is to use the misc/
stage_biblios_file.pl script. That can handle as much data as you can throw
at it.

Also, there is an important issue when importing large files: there are
certain circumstances when trying to stage a large file results in the
database growing to about six times the size it needs to be to store that
number of records. Unfortunately, I don't know exactly what the conditions
are. The way I dealt with this ultimately was to clean all the failed
imports, do a mysqldump of the entire database, drop the database, and
recreate it.

Good luck.

Regards,
Jared Camins-Esakov
