Issue XD-872: Make in-memory meta data stores persistent
Just wanted to create story for this - so we can consider whether this should be addressed. In at least 2 modules we use non-persisted states. We may want to consider making them persistent: *Twitter Search* uses an in-memory *MetadataStore* that keeps track of the twitter ids. There exists a corresponding issue for Spring Integration: "Create a Redis-backed MetadataStore" See: https://jira.springsource.org/browse/INT-3085 *File Soure*'s File Inbound Channel Adapter uses a AcceptOnceFileListFilter, which uses an in-memory Queue to keep track of duplicate files.
