CGSpace Notes

2023-08-03

• I finally got around to working on Peter’s cleanups for affiliations, authors, and donors from last week
  • I did some minor cleanups myself and applied them to CGSpace
• Start working on some batch uploads for IFPRI

2023-08-04

• Minor cleanups on IFPRI’s batch uploads
  • I also did a duplicate check and found thirteen items that seem to be duplicates, so I sent them to Leigh to check
• I read this interesting blog post about PostgreSQL’s log_statement function
  • Someone pointed out that this also lets you take advantage of PgBadger analysis
  • I enabled statement logging on DSpace Test and I will check it in a few days
• Reading about DSpace 7 REST API again
  • Here is how to get the first page of 100 items: https://dspace7test.ilri.org/server/api/discover/search/objects?dsoType=item&page=1&size=100
  • I really want to benchmark this to see how fast we can get all the pages
  • Another thing I notice is that the bitstreams are not here, so that will be an extra call…

• Export CGSpace to check for missing Initiative collection mappings
• Start a harvest on AReS

• I’m checking the PostgreSQL logs now that statement logging has been enabled for a few days on DSpace Test
  • I see the logs are about 7 or 8 GB, which is larger than expected—and this is the test server!
  • I will now play with pgbadger to see if it gives any useful insights
  • Hmm, it sems the log_statement advice was old as pgbadger itself says:

Do not enable log_statement as its log format will not be parsed by pgBadger.

… and:

Warning: Do not enable both log_min_duration_statement, log_duration and log_statement all together, this will result in wrong counter values. Note that this will also increase drastically the size of your log. log_min_duration_statement should always be preferred.

• So we need to follow pgbadger’s instructions rather to get a suitable log file
  • After enabling the new settings I see that our log file is going to be reaallllly big… hmmmm will check tomorrow morning
• More work on the IFPRI batch uploads
