Loading into Voyager
MARCIVE provides batches of 50,000 records
Voyager suggests loads of 10,000 per batch
MarcEdit to the rescue
Already have Voyager 001s in records, so no complex matching needed
Start Loading!
Keyword Indexing (How NOT to import)
Pre Voyager 9.0 (we were on 8.2)
Default import performed keyword indexing
Generates a temporary index file
Each record loaded takes a tiny bit longer to load than previous record
If temporary file gets too large, the system crashes
Required nightly keyword index regeneration
Only 20k to 30k records per day loaded
1 example log showed 10k record loaded in 2 hours 14 minutes
The NEXT 10k took 4 hours
No Keyword Index (How to import)
Pre Voyager 9.0, Pbulkimport –X (NOKEY Disable keyword index and maintenance)
As of Voyager 9.0, this is the DEFAULT for Pbulkimport
Each batch of 10k took just under 1 hour
3 loads per day vs 8 per day
Single Keyword Regen at project completion
Authorities Records Loads
Decision was made not to wipe out existing authorities database
Voyager retains heading ids to match on – easy!
Also loaded in batches of 10k
Kept the –X switch, but no idea if it mattered
