Alter Schema slower for v20

boedy · September 23, 2020, 2:58pm

I just swapped out a v1.2.3 instance for a v20.07.1 version. I currently only have it running on my development machine. I’m noticing that my integration tests are running about twice as slow compared to the v1.x versions. For each test the schema is dropped and recreated. It seems the schema alteration command is the cause of the slower tests.

Is this to be expected?
