[JBoss JIRA] (ISPN-5572) Exposed JMX MBeans should be separate components

by Dan Berindei (JIRA)

[ https://issues.jboss.org/browse/ISPN-5572?page=com.atlassian.jira.plugin.... ] Dan Berindei updated ISPN-5572: ------------------------------- Fix Version/s: 8.2.0.CR1 (was: 8.2.0.Beta1) > Exposed JMX MBeans should be separate components > ------------------------------------------------ > > Key: ISPN-5572 > URL: https://issues.jboss.org/browse/ISPN-5572 > Project: Infinispan > Issue Type: Task > Components: Core > Affects Versions: 8.0.0.Alpha2, 7.2.3.Final > Reporter: Dan Berindei > Fix For: 8.2.0.CR1 > > > We currently expose internal components as JMX MBeans, and that makes our JMX "API" very unstructured. The exposed MBeans should be separate components, and the only concern in their interfaces should be ease of use. > One example of JMX getting in the way of refactoring is {{CacheMgmtInterceptor}}. The interceptor chain is dynamic, so it should be possible to insert the interceptor only when statistics are enabled. But because the {{statisticsEnabled}} attribute is on the interceptor itself, that becomes a lot trickier, and we had to introduce a separate configuration attribute that disables statistics permanently (ISPN-5542). -- This message was sent by Atlassian JIRA (v6.4.11#64026)

[JBoss JIRA] (ISPN-5570) Cross-site: retry backup commands

by Dan Berindei (JIRA)

[ https://issues.jboss.org/browse/ISPN-5570?page=com.atlassian.jira.plugin.... ] Dan Berindei updated ISPN-5570: ------------------------------- Fix Version/s: 8.2.0.CR1 (was: 8.2.0.Beta1) > Cross-site: retry backup commands > --------------------------------- > > Key: ISPN-5570 > URL: https://issues.jboss.org/browse/ISPN-5570 > Project: Infinispan > Issue Type: Bug > Components: Core, Cross-Site Replication > Affects Versions: 7.2.3.Final > Reporter: Dan Berindei > Fix For: 8.2.0.CR1 > > > There are 3 phases in a backup RPC: > 1. Sender -> Local site master: caused by the site master is shutting down or crashing, or by a network split. > 2. Local site master -> Remote site master: > 2.1. Local site master is no longer a site master, e.g. because it's shutting down or because it's no longer coordinator after a merge. > 2.2. Remote site master is not longer a site master. > 2.3. Link between local site and remote site is down. > 3. Remote site master -> Backup targets > Replication failures in phase 3 are handled by retrying (except for TimeoutExceptions), because {{BaseBackupReceiver}} uses regular cache methods to perform the updates. > But replication failures in phases 1 and 2 are not handled in any way, except for causing the remote site to be taken offline after a certain number of replication failures (if backup is synchronous). We should instead retry backup RPCs when we get a {{SuspectException}} or {{UnreachableException}}, and perhaps even when we get no response (2.2?), and only stop when the timeout expires or when the backup is taken offline. > Async backup probably needs retrying as well, and perhaps even a more sophisticated approach like I-RAC (ISPN-2634). -- This message was sent by Atlassian JIRA (v6.4.11#64026)

[JBoss JIRA] (ISPN-5574) Define high-level cache capabilities

by Dan Berindei (JIRA)

[ https://issues.jboss.org/browse/ISPN-5574?page=com.atlassian.jira.plugin.... ] Dan Berindei updated ISPN-5574: ------------------------------- Fix Version/s: 8.2.0.CR1 (was: 8.2.0.Beta1) > Define high-level cache capabilities > ------------------------------------ > > Key: ISPN-5574 > URL: https://issues.jboss.org/browse/ISPN-5574 > Project: Infinispan > Issue Type: Feature Request > Components: Configuration, Core > Affects Versions: 7.2.3.Final > Reporter: Dan Berindei > Priority: Minor > Fix For: 8.2.0.CR1 > > > Infinispan's configuration is very flexible, and it's sometimes hard to figure out how different settings affect things like cache consistency. > For example, the lucene-directory module uses the fairly complicated {{Configurations.noDataLossOnJoiner()}} method to validate that a cache is safe for storing lucene indexes. > Another example is users who would like to use a store for backup, but they don't want read from the store for M/R tasks or when get(k) doesn't find the key in memory. > One idea would be to define a set of "capabilities" like "state-transfer-complete" or "all-data-in-memory". The user could then add those capabilities in the cache definition, and the cache won't start if the configuration violates those capabilities. The capabilities would also be used internally, to improve the error message when a feature requires a particular combination of settings. -- This message was sent by Atlassian JIRA (v6.4.11#64026)

[JBoss JIRA] (ISPN-5575) Shared write-behind store can read stale entries on joiner

by Dan Berindei (JIRA)

A joiner can then read from the shared store a stale version of entries that have updates in the modification queue but are no longer in memory (because they were either removed explicitly, or evicted). -- This message was sent by Atlassian JIRA (v6.4.11#64026)

[JBoss JIRA] (ISPN-5557) Core threading redesign

by Dan Berindei (JIRA)

This causes various issues, from general context switching overhead to the thread pools getting full and causing deadlocks. > We should redesign the core so that most blocking happens on the application threads, and the number of internal threads is kept to a minimum. -- This message was sent by Atlassian JIRA (v6.4.11#64026)

[JBoss JIRA] (ISPN-5533) M/R DeltaAwareList can add duplicate values because of topology changes

by Dan Berindei (JIRA)

Because a {{PutKeyValueCommand(K, DeltaAwareList)}} command is not idempotent, a retried command will append extra intermediate values to the list. > The M/R framework tries to guard against this by waiting for all the nodes to initialize the intermediate cache before starting the reduce phase, but it cannot guard against nodes joining or leaving during the reduce phase. -- This message was sent by Atlassian JIRA (v6.4.11#64026)

[JBoss JIRA] (ISPN-5642) Reduce contention in the RPC timeout handling

by Dan Berindei (JIRA)

This means the scheduler spends a lot of time reordering the elements of its DelayQueue. > It should be possible to store the tasks with a long timeout (e.g. 1s) in a queue and only move them to the scheduler's priority queue when they have less than 1s to expiration (e.g. by a worker thread that runs every 0.5s) > Storing all the tasks in a single queue may be impractical because the worker thread would have more and work to do as load increases and the RPCs take longer to finish, so a [hashed timing wheel|http://www.cse.wustl.edu/~cdgill/courses/cs6874/TimingWheels.ppt] may be needed. -- This message was sent by Atlassian JIRA (v6.4.11#64026)
