> NIFI-4069 added target system timestamp detection for ListXXXX processors. Defaults to auto detection. Most sub classes added 'Target System Timestamp Precision' to their 'getSupportedPropertyDescriptors' method. But ListAzureBlobStorage didn't.
> Even though 'Target System Timestamp Precision' property has a default value, if it's not included in getSupportedPropertyDescriptors method, the property value becomes null, instead of the default value. This combination is not handled well in AbstractListProcessor currently. That makes ListAzureBlobStorage behaves as if Azure Blob Storage time precision is in Minutes while it actually has Seconds precision. Incurs longer time for blob files to be picked than required.
> Not having 'Target System Timestamp Precision' at ListAzureBlobStorage seems reasonable as the processor interact with only Azure Blob Storage, and its timestamp precision should be fixed. AbstractListProcessor should provide an extension point for sub-classes to define default precision. In case for Azure Blob, it's SECONDS.
