- I always forget how to copy the reconciled values in OpenRefine, but you need to make a new column and populate it using this GREL: `if(cell.recon.matched, cell.recon.match.name, value)`
- I mapped all 170 items to their appropriate collections based on type and uploaded them to CGSpace
## 2020-03-16
- I'm looking at the CPU usage of CGSpace (linode18) over the past year and I see we *rarely* even go over two CPUs on average sustained usage:
![linode18 CPU usage year](/cgspace-notes/2020/03/cgspace-cpu-year.png)
- Also clearly visible is the effect of CPU steal in 2019-03
![linode18 RAM usage year](/cgspace-notes/2020/03/cgspace-memory-year.png)
![linode18 JVM heap usage year](/cgspace-notes/2020/03/cgspace-heap-year.png)
- At max we have committed 10GB of RAM, the rest is used opportunistically by the filesystem cache, likely for Solr
- There was a huge drop in 2019-07 when I changed the JVM settings
- I think we should re-evaluate our deployment and perhaps target a different instance type and add block storage for assetstore (as we determined Linode's block storage to be too slow for Solr)

<li>There was a huge drop in 2019-07 when I changed the JVM settings</li>
