[Evergreen-catalogers] Vandelay and large files

[Mary Llewellyn]

Thanks, Kathy. I'll set up another matchpoint just for these OneClickDigital
(or, as I like to call them, OCD) records, since they should have the same
001, so I don't have to worry about matching on 020.

Wish me luck!

Mary

Hi Mary,

I believe the MassLNC consortium that is live on Evergreen is typically
loading files with fewer than 100 records. From what I understand, they are
not having problems with load times.

We do have another consortium, though, that is experiencing problems with
load times for any size file if they are using a match set that matches on
the 020, 022 or 024 field. I don't know if it's related, but, during the
development, we had asked for some normalization on these fields (the 020
field in particular) so that incoming records could match when there is pbk
or other trailing text at the end of the field.

Since this problem is happening in one Evergreen instance but not the other,
we're looking at the possibility that we may be missing an index. 
I don't know if there are any other system configuration issues we should be
looking at. As soon as we identify the source of the problem, I'll be happy
to share it with the list.

FWIW, when I was testing, there were a couple of instances where I
accidentally loaded files with more than 1,000 records, and, even though it
took some time, the processing ultimately completed. However, I don't recall
now what kind of matching I was doing.

I'm sorry I couldn't be more help on this one!

Kathy
