What you actually did
Deploy a new instance, checked that
maxLeaseId was not greater than the maxLeaseId that I wanted to set on post-install. This key/value is not present.
Why that wasn’t great, with examples
When building logic workflows downstream of the Dgraph deployment, checking the
curl -sS 'http://<zero_endpoint>:6080/state' | jq .maxLeaseId -r will return null when data has not been loaded.
I would propose that the above scenario return
maxLeaseId: -1 instead. This has a number of advantages:
- Schema is static (at least for this key)
- We explicitly know a max has not been set yet
- Single data type
- Downstream workflows do not need to check for a
