(I’m running in Kubernetes at the moment)
I’m trying to do an upgrade from v1.1.1 to v20.07.0. I’ve exported my data which comes to about 28 million quads and I’m trying to import it into the database instance into which I’m upgrading using the live loader. I believe I’m running into some memory issues; on the clusters where the upgrade has succeeded I’ve noticed that the Alpha node tends to hit 6-7gb resident and cruise around there. In other, less-successful restorations, the pod terminates and when it restarts the live loader is unable to resume, it sits at 0 transactions committed indefinitely after.
When I run
top on the Alpha after the CPU usage is quite high but it doesn’t seem to be doing anything. The Alpha log contains these entries, approximately one a minute:
