SpiceDB is an open source, Google Zanzibar-inspired, database system for creating and managing security-critical application permissions.

SpiceDB

also I just saw these:
```
      --update-relationships-max-preconditions-per-call uint16        maximum number of preconditions allowed for WriteRelationships and DeleteRelationships calls (default 1000)
      --write-relationships-max-updates-per-call uint16               maximum number of updates allowed for WriteRelationships calls (default 1000)
```
what happens if those get too big? like were they limited because of the work the datastore would have to do?
