Re: [infinispan-dev] Integration between HotRod and OGM

It's an interesting approach that would work fine-ish for entities assuming the Hot Rod client is multi threaded and assuming the client uses Future to parallelize the calls. But it won't work for associations as we have them designed today. Each association - or more precisely the query results t

Re: [infinispan-dev] Design of Remote Hot Rod events

Dear Galder, I have read with great interest the design document your wrote for Hot Rod remote eventing [1]. In the perspective of the LEADS project, that aims at building a continuous query/streaming engine on top of Infinispan, this new feature seem very promising. However, it seems that in the

We could if someone puts a gun to my head. But that would be the *only* backend that has to rely on query for its association. Hibernate OGM has a strong design bias towards totally controlling how CRUD is done to guarantee the consistency. If you introduce a search engine, all bets are off. On T

[infinispan-dev] configuration toProperties

Hi, This is a configuration output format feature proposal. I'd like to be able to flatten the infinispan cache configuration to flat properties style so that two configurations can be easily comparable in a view that displays sorted matching properties side by side to quickly spot differences.

Re: [infinispan-dev] configuration toProperties

I love the idea, especially as it happened to me to try to help someone who was running Infinispan configured via other means (like the AS7 configuration format), and it's always hard to understand how it's actually configured without knowing all the implicit default values, on a specific version (

No need for java.util.Properties, the main feature I want is - Configuration displayable as collection of flat key-value properties - Hierarchy (e.g. l1 is under clustering) is expressed via extending the prefix and dividing by dot '.' but it would be usefull if the outputformat was easily parcea

Re: [infinispan-dev] rethinking ISPN transactions

Sorry, I was confusing things - the timeout I was thinking of happened in the transaction manager itself, and it didn't matter whether we were registering a synchronization or a full XA resource. Replication timeout sounds like something that could be easily removed for commit command RPCs, but th

I think the properties format is too closely tied to your particular use case - in general having a long prefix on every line would actual settings harder to see than in a structured format like XML/JSON/YAML, not easier.

Is there any reason to use synchronization other than "it's faster"? IMO, the reasoning for removing synchronizations is the same as item 1 in your proposal, "Async options for commit/rollback". On Tue, Nov 19, 2013 at 6:35 PM, Mircea Markus wrote: > > On Nov 19, 2013, at 4:01 PM, Dan Berindei

Re: [infinispan-dev] configuration toProperties

+1 to the general idea. -1 to using Properties format (or *any* new format). Using any format that ISPN can't directly read back in ties the functionality only to your specific use case. But If it's in a configuration format that ISPN can read back in, it would be much more generally useful.

Re: [infinispan-dev] configuration toProperties

Important part of this is expressing the Configuration state as it was constructed in the JVM, either by parsing or programmatically and not omitting any of the attributes (properties) btw reflection is another way to go, I just wasn't sure what is the preferred way and where I'd put the reflec

Dennis, why would you propose it to be in a format that can be read back? It wouldn't be as simple, and you'd have to face all the complexities of supporting different version formats, etc.. Unless you've come across use cases for a JSON-like configuration? I'd go for Properties or the simple toSt
