is trying to import 6 million+ rows, that's about 650 connections each trying to shove through 9k tuples. 3. Postgres and MySQL both have a limit on how many placeholders you can have in a single query. This appears to be 65535 for Postgres and MySQL (https://stackoverflow.com/a/49379324, https://stackoverflow.com/a/24447922). This roughly translating to a maximum of 9362 relationship tuple writes (assuming each is going to require 7 placeholders). I didn't initially hit this limitation because I was testing with an in memory database. The conclusion is, I think augmenting
to support large scale relationship sets will require a bit more design and planning than my initial hacky batching solution offers and might extend to making changes to SpiceDB, not just
so it's possible to batch the batches (this is really just turtles all the way down 🐢 ).
