Spring Operator

**[Erwin Vervaet](https://jira.spring.io/secure/ViewProfile.jspa?name=klr8)** commented Another idea: we could possibly do this using the decorator pattern, i.e. leveraging the FlowBuilder interface.

**[Dave Syer](https://jira.spring.io/secure/ViewProfile.jspa?name=david_syer)** commented I know this is my issue, but I can't think of a good use case that can't be addressed with transaction isolation. Over to Mark to remind...

**[Mark Fisher](https://jira.spring.io/secure/ViewProfile.jspa?name=mark.fisher)** commented IIRC one of the discussions that led to this issue was related to ensuring FIFO ordering when using a MessageStore-backed MessageChannel. Another concern would be for Aggregators...

**[Oleg Zhurakousky](https://jira.spring.io/secure/[email protected])** commented I think it would be interesting to get more details on how we can get a hold of RegionQueue described in https://wiki.springsource.com/display/GMFI/Gemfire+API+TODOs (if MessageStore is Gemfire). But...

**[Dave Syer](https://jira.spring.io/secure/ViewProfile.jspa?name=david_syer)** commented `@Oleg`: MessageGroupQueue **is** a global queue implementation provided the store is global. #5237 and the demo I set up on githib for Brian proved that this works...

**[Brian Dussault](https://jira.spring.io/secure/ViewProfile.jspa?name=dussab)** commented The following link is how Oracle ESB provides a cluster wide locking mechanism for resequencing: http://download.oracle.com/docs/cd/E12524_01/doc.1013/e12638/sequencer.htm Another area for "locking" might be for things such as polling...

**[Dave Syer](https://jira.spring.io/secure/ViewProfile.jspa?name=david_syer)** commented We already support global resequencing and locking in polling adapters (which we proved with that demo in #5237). As long as the database supports transaction isolation it...

**[Mark Fisher](https://jira.spring.io/secure/ViewProfile.jspa?name=mark.fisher)** commented Dave, I'm reassigning to you in case you have changed your mind. Otherwise, I'd say we should perhaps resolve as "deferred" and/or remove the target version for...

**[Anderson Balduino](https://jira.spring.io/secure/ViewProfile.jspa?name=andersonm)** commented Dave, we will use an aggregator based on Infinispan. This issue is addressing the possibility of multiple concurrent access aggregator in a distributed environment?

**[Dave Syer](https://jira.spring.io/secure/ViewProfile.jspa?name=david_syer)** commented Correct. And the current plan is to do nothing, since the only implementation of a global store we provide out of the box in Spring Integration has...
