[jira] [Commented] (NIFI-10428) Allow for loading Avro record schema from files
[ https://issues.apache.org/jira/browse/NIFI-10428?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17614255#comment-17614255 ]
Daniel Stieglitz commented on NIFI-10428:
-----------------------------------------
[~john.wise] [~mike.thomsen] I am almost done developing my first cut at this. I am not using dynamic properties. I am just using a directory where I can scan for schemas, validate them and load them into a ConcurrentHashMap. The drawback I am realizing now is that there is no way to know what is in the registry unless I log at intervals. Is that a major drawback? If it is do either you have any suggestions how I can improve on that?

> Key: NIFI-10428
> URL: https://issues.apache.org/jira/browse/NIFI-10428
> Project: Apache NiFi
> Issue Type: New Feature
> Components: Core Framework
> Affects Versions: 1.18.0
> Reporter: Daniel Stieglitz
> Assignee: Daniel Stieglitz
> Priority: Major
> Labels: Record, avro, registry, schema
>
> 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.
