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

by Tristan Tarrant (JIRA)

[ https://issues.jboss.org/browse/ISPN-5570?page=com.atlassian.jira.plugin.... ] Tristan Tarrant updated ISPN-5570: ---------------------------------- Fix Version/s: 9.0.0.Beta2 (was: 9.0.0.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: 9.0.0.Beta2 > > > 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 (v7.2.3#72005)

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

by Tristan Tarrant (JIRA)

[ https://issues.jboss.org/browse/ISPN-5574?page=com.atlassian.jira.plugin.... ] Tristan Tarrant updated ISPN-5574: ---------------------------------- Fix Version/s: 9.0.0.Beta2 (was: 9.0.0.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: 9.0.0.Beta2 > > > 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 (v7.2.3#72005)

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

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

[JBoss JIRA] (ISPN-5584) Support fine-grained write skew check for FineGrainedAtomicMap entries

With pessimistic locking, fine-grained maps allow the user to modify different sub-keys concurrently, we should allow the same with optimistic locking. -- This message was sent by Atlassian JIRA (v7.2.3#72005)

[JBoss JIRA] (ISPN-5515) Purge store if there is another node already running

When joining the existing members, the cache then waits to receive the first CH in which it is a member, and then deletes only the entries in the segments that it doesn't own in that CH. > The intention of this was to remove as little as possible from the existing data, e.g. if the first node to start up is not the one that was stopped last. But the preloaded entries are not replicated to the other nodes, so this can lead to inconsistencies. > It would be better to delay preloading until we know we are the first node to start up, but failing that we could clear the data container and the store before receiving the initial state. > Note that this will only allow preloading data from one node. Restoring data from more nodes is harder to do, and we will implement it as part of graceful restart. -- This message was sent by Atlassian JIRA (v7.2.3#72005)

[JBoss JIRA] (ISPN-5513) State Transfer can miss entries that are concurrently activated

However if an entry is activated during or after the data container iteration it is possible this entry is then not seen and subsequently is not present in the store when it is processed. > EntryRetriever had this same issue and it was required to register a cache listener to listen for activations and then replay the data after finishing with the store. > This can cause duplicate values as well, however replacing the same exact value is fine and if a non ST write occurs the state is ignored anyways. -- This message was sent by Atlassian JIRA (v7.2.3#72005)
