Joe Witt commented on NIFI-10428:
---------------------------------
They do all have a design which considers operating in a clustered environment.
Ones where this is inherently problematic have more awkward solutions like
something that is a CS meant to run on all nodes to hold state but is actually
only interacted with by clients that talk to a single node. These solutions
are inelegant for sure. Our DistributedMapCache(Server/Client) examples apply
here.
This is why we've not done this file based approach already as it is just
wonky. You want a real Schema Registry service and then nifi acts as a client
to it...
> Allow for loading Avro record schema from files

> Project: Apache NiFi
> Issue Type: New Feature
> Components: Core Framework
> Affects Versions: 1.18.0

> Time Spent: 10m
> Remaining Estimate: 0h

> The various record reader and writer controllers XML, CSV, JSON and AVRO, etc
> can load schemas from a registry service. The AvroSchemaRegistry can only
> load its schema from a text property. It would be useful to have a file
> based Avro schema registry, with a configurable refresh interval to allow for
> adding, removing or updates to schema files.
