looks unused, remove it?
Otherwise I think it would have to use the blob
schema, such as REFRESH TABLE blob."{self.name}";

Yeah, I also recognized this detail yesterday. Thank you. So, effectively, there is no way to run a BLOB table in a different schema? It is always blob
?

Yes it's always blob
, see also https://cratedb.com/docs/crate/reference/en/5.4/sql/statements/create-blob-table.html (syntax does not support to define a schema name).
FYI: I've just reused that basic implementation over at crate/mlflow-cratedb#33, adding more features to implement an object store. |
About
The guideline at the Python client documentation about working with the CrateDB BLOB store is sweet, but a runnable program is even better.
Synopsis
Backlog
we may want to think about shipping it in one way or another,
because it is a good building block.
