- Atmire responded about the issue with duplicate data in our Solr statistics
- They noticed that some records in the statistics-2015 core haven't been migrated with the AtomicStatisticsUpdateCLI tool yet and assumed that I haven't migrated any of the records yet
- That's strange, as I checked all ten cores and 2015 is the only one with some unmigrated documents, as according to the `cua_version` field
- I started processing those (about 411,000 records):
- Udana emailed me yesterday to ask why the CGSpace usage statistics were showing "No Data"
- I noticed a message in the Solr Admin UI that one of the statistics cores failed to load, but it is up and I can query it...
- Nevertheless, I restarted Tomcat a few times to see if all cores would come up without an error message, but had no success (despite that all cores ARE up and I can query them, _sigh_)
- I think I will move all the Solr yearly statistics back into the main statistics core
- Start testing export/import of yearly Solr statistics data into the main statistics core on DSpace Test, for example:
```
$ ./run.sh -s http://localhost:8081/solr/statistics-2010 -a export -o statistics-2010.json -k uid
$ ./run.sh -s http://localhost:8081/solr/statistics -a import -o statistics-2010.json -k uid
- I deployed Tomcat 7.0.107 on DSpace Test (CGSpace is still Tomcat 7.0.104)
- I finished migrating all the statistics from the yearly shards back to the main core
## 2020-12-05
- I deleted all the yearly statistics shards and restarted Tomcat on DSpace Test (linode26)

- Looking into the statistics on DSpace Test after I migrated them back to the main core
- All stats are working as expected... indexing time for the DSpace Statistics API is the same... and I don't even see a difference in the JVM or memory stats in Munin other than a minor jump last week when I was processing them
- I will migrate them on CGSpace too I think
- First I will start with the statistics-2010 and statistics-2015 cores because they were the ones that were failing to load recently (despite actually being available in Solr WTF)
- I will migrate all these cores and see if it makes a difference, then probably end up migrating all of them
- I removed the statistics-2010, statistics-2015, statistics-2016, and statistics-2018 cores and restarted Tomcat and _all the statistics cores came up OK and the CUA statistics are OK_!
$ psql -c 'SELECT * FROM pg_locks pl LEFT JOIN pg_stat_activity psa ON pl.pid = psa.pid;' | wc -l
1739

- Atmire sent some instructions for using the DeduplicateValuesProcessor
- I modified `atmire-cua-update.xml` as they instructed, but I get a million errors like this when I run AtomicStatisticsUpdateCLI with that configuration:
```

- They responded with an updated CUA (6.x-4.1.10-ilri-RC7) that has a fix for the duplicates processor _and_ a possible fix for the database locking issues (a bug in CUASolrLoggerServiceImpl that causes an infinite loop and a Tomcat timeout)
- I deployed the changes on DSpace Test and CGSpace, hopefully it will fix both issues!
- In other news, after I restarted Tomcat on CGSpace the statistics-2013 core didn't come back up properly, so I exported it and imported it into the main statistics core like I did for the others a few days ago
- Sync DSpace Test with CGSpace's Solr, PostgreSQL database, and assetstore...

- I was running the AtomicStatisticsUpdateCLI to remove duplicates on DSpace Test but it failed near the end of the statistics core (after 20 hours or so) with a memory error:
```
Successfully finished updating Solr Storage Reports | Wed Dec 09 15:25:11 CET 2020
- The statistics-2019 core finished processing the duplicate removal so I started the statistics-2017 core
- Peter asked me to add ONE HEALTH to ILRI subjects on CGSpace
- A few items that got "lost" after approval during the database issues earlier this week seem to have gone back into their workflows
- Abenet approved them again and they got new handles, phew
- Abenet was having an issue with the date filter on AReS and it turns out that it's the same `.keyword` issue I had noticed before that causes the filter to stop working
- I fixed the filter to use the correct field name and filed a bug on OpenRXV: https://github.com/ilri/OpenRXV/issues/63
- I checked the Solr statistics on DSpace Test to see if the Atmire duplicates remover was working, but now I see a comical amount of duplicates...
- I sent feedback about this to Atmire
- I will re-sync the Solr stats from CGSpace so we can try again...
- In other news, it has been a few days since we deployed the fix for the database locking issue and things seem much better now:
- I tried to harvest a few times on OpenRXV in the last few days and every time it appends all the new records to the items index instead of overwriting it:
