No, that's the whole point of having this scanning "framework" -- we do it all (all sorts of indexing, ...) in a single pass. What we need is just to properly prepare the info, so when the query is invoked, it's basically O(1) lookup. So, split methods make sense to me, as then all we do is Set::intersect. Or am I missing something? -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/533815#533815] Start a new discussion in JBoss Microcontainer Development at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

[Clustering Development] - Exposing Infinispan CacheManager's in the AS

by Brian Stansberry

Brian Stansberry [http://community.jboss.org/people/bstansberry%40jboss.com] created the discussion "Exposing Infinispan CacheManager's in the AS" To view the discussion, visit: http://community.jboss.org/message/533814#533814 -------------------------------------------------------------- Discussion thread related to https://jira.jboss.org/jira/browse/JBAS-7838 https://jira.jboss.org/jira/browse/JBAS-7838 I was talking to Bela today about adding scopes to JGroups messages (see https://jira.jboss.org/jira/browse/JGRP-822 https://jira.jboss.org/jira/browse/JGRP-822) and the solution to that is still a bit up in the air. He's got clear ideas and may have something done pretty shortly, but IMO it's risky for the AS to count on having a scoping solution in JGroups and consumed by Infinispan in time for AS 6.0 M4. Without a good scoping solution, I think it's wise to have different services (i.e. web session management, SFSB management, Hibernate 2LC, HAPartition) use a separate JGroups channel. Otherwise messages from one service will block in the receiver's NAKACK/UNICAST behind other messages from the same sender for different services. This means we would use a different CacheManager for the different services. JBAS-7838 says to just use one by default, but I'm pretty convinced we should have more than one. We need to support that in the long run anyway. Options, comments are appreciated: 1) Everything shares a single CacheManager/Channel. 2) 4 separate channels: Web, SFSB, Hibernate, HAPartition. A la AS 5. 3) 3 separate channels: Web+SFSB, Hibernate, HAPartition. Here web sessions and SFSBs use the same channel, which can be useful in the future when Infinispan supports sending a single 2PC message pair at tx commit for a tx that crosses several caches. So, a web request modifies a session and modifies an SFSB, we could get a single 2PC. Hmm, if the web session and SFSB mapped to different nodes with DIST, there would be 2 messages anyway, so the utility of #3 is less. So, I'm leaning toward #2 but am quite open to persuasion. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/533814#533814] Start a new discussion in Clustering Development at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

Remy Maucherat [http://community.jboss.org/people/remy.maucherat%40jboss.com] replied to the discussion "Servlet Scanner plugin" To view the discussion, visit: http://community.jboss.org/message/533813#533813 -------------------------------------------------------------- The first one is for the standard EE annotations, nothing special. The second one mixes annotations with types because that's what that SCI feature does. It allows specifying a set of annotations, or a set of types, and you get in a listener a Set of the classes in the webapp that respectively use the annotations (type, method, field), or are a subclass or imlplement the specified types. No need for sorting, it's a single Set with everything. I was sugesting a single method since it could avoid loops going through all the classes, right ? -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/533813#533813] Start a new discussion in JBoss Microcontainer Development at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

I would not re-use it, better writting new behavior in separate plugin. > - public Set<Class<?>> getClasses(List<VirtualFile> classpath, Set<Class<? extends Annotation>> annotationsToLookFor, Set<Class<?>> supertypesToLookFor) (note: in case there are multiple SCIs with HandlesType, this could be less efficient than using a map to pass the annotations/types to look for, and getting a map back; of course, it is simpler too) Can you explain this one a bit more. Or, why mix the parameters; annotation and supertypes? We already have the annotations method, simply adding the supertypes, and the use Set intersection to get both? -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/533807#533807] Start a new discussion in JBoss Microcontainer Development at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

Re: [jboss-dev-forums] [Clustering Development] - How to write your own load balancing rule in mod_cluster?

by Brian Stansberry

Brian Stansberry [http://community.jboss.org/people/bstansberry%40jboss.com] replied to the discussion "How to write your own load balancing rule in mod_cluster?" To view the discussion, visit: http://community.jboss.org/message/533797#533797 -------------------------------------------------------------- I don't think of it as being round-robin. The ModClusterService on each appserver side provides the httpd side a metric indicating how much load it's under. When the httpd side detects a request for a new session it picks the server to route to based on the relative load. There may be some round-robinish bit that goes in case of a tie, but that's not the critical factor. So I'm not sure what you're looking to change. There are a lot of options for configuring how the load metric is calculated; see the docs. Any change to how the httpd side picks a server based on the relative load metrics will involve changes to the C code for the Apache httpd modules. If you still think there's a use case for customizing that, suggest you post on the mod_cluster forum at http://community.jboss.org/en/mod_cluster http://community.jboss.org/en/mod_cluster where Jean-Frederic Clere, the man most familiar with the C side of things, is more likely to see your question. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/533797#533797] Start a new discussion in Clustering Development at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]
