[JBoss JIRA] (ISPN-8860) Lazy start counter's caches
by Pedro Ruivo (JIRA)
[ https://issues.jboss.org/browse/ISPN-8860?page=com.atlassian.jira.plugin.... ]
Pedro Ruivo updated ISPN-8860:
------------------------------
Fix Version/s: 9.2.1.Final
> Lazy start counter's caches
> ---------------------------
>
> Key: ISPN-8860
> URL: https://issues.jboss.org/browse/ISPN-8860
> Project: Infinispan
> Issue Type: Enhancement
> Components: Clustered Counter
> Reporter: Pedro Ruivo
> Assignee: Pedro Ruivo
> Fix For: 9.2.1.Final
>
>
> Goal: if counter's are used, there is no need to start counter's caches!
> Main change:
> * remove {{__counter_configuration}} and use the {{state-cache}} to store counter's configuration
> Summary:
> * When the first counter is defined and stored in the {{state-cache}}, the {{__counter}} cache is started.
> * When a node joins, it starts the {{__counter}} cache if it finds a counter's configured stored
> * We need to persist the counter's configuration (for persisted counters only!) manually since the {{state-cache}} isn't persisted
> Issues
> * the {{state-cache}} is available during partitions! same counter can be defined with different configuration :(
> users have to deal with it while I can't find a way to resolve a conflict.

[JBoss JIRA] (ISPN-8981) Generate Hot Rod parser automatically
by Radim Vansa (JIRA)
Radim Vansa created ISPN-8981:
---------------------------------
Summary: Generate Hot Rod parser automatically
Key: ISPN-8981
URL: https://issues.jboss.org/browse/ISPN-8981
Project: Infinispan
Issue Type: Enhancement
Components: Server
Affects Versions: 9.2.0.Final
Reporter: Radim Vansa
Assignee: Radim Vansa
Fix For: 9.3.0.Final
This JIRA has two objectives:
1. reduce number of allocated objects
2. improve the parsing on server side to avoid chains of lambda mappings
Manual parsing of Hot Rod protocol, invoking recursive methods that return {{Optional}}s or {{Optional<Optional<...>}}s seems to generate a lot of garbage. A better approach would be a finite state automaton that would read the byte stream and invoke callbacks.
Such automaton can be generated from a high-level grammar as part of the build process.
Along with these changes we can remove the {{Response}} abstraction and write responses directly as {{ByteBuf}}s.

[JBoss JIRA] (ISPN-8980) High concurrency : Infinispan Directory Provider: Lucene : Error loading metadata for index file
by Debashish Bharali (JIRA)
[ https://issues.jboss.org/browse/ISPN-8980?page=com.atlassian.jira.plugin.... ]
Debashish Bharali commented on ISPN-8980:
-----------------------------------------
Sure we will try once removing *'locking_strategy'* property.
As per what I am able to make out of your comment is that:
# We should remove this property, and Infinispan will handle the locking itself.
# And this will work even for clustered env.

[ https://issues.jboss.org/browse/ISPN-8980?page=com.atlassian.jira.plugin.... ]
Gustavo Fernandes edited comment on ISPN-8980 at 3/22/18 1:39 PM:
------------------------------------------------------------------
Lucene indexes cannot be written by more than a process at the same time as it will cause corruption, very similar to what you are observing.
Using NONE is only safe if only one process writes to the index at a time. In theory you don't need SINGLE since Infinispan has its own internal LockFactory that stores the lock in a cache.
Could you try out simply removing the lock factory as I suggested before?

[JBoss JIRA] (ISPN-8980) High concurrency : Infinispan Directory Provider: Lucene : Error loading metadata for index file
by Gustavo Fernandes (JIRA)
[ https://issues.jboss.org/browse/ISPN-8980?page=com.atlassian.jira.plugin.... ]
Gustavo Fernandes commented on ISPN-8980:
-----------------------------------------
Lucene indexes cannot be written by more than a process at the same time as it will cause corruption, very similar to what you are observing.
Using NONE is only safe if only one process writes to the index at a time. In theory you don't need single since Infinispan has its own lock manager that stores the lock in a cache.
Could you try out simply removing the lock factory as I suggested before?

[JBoss JIRA] (ISPN-8980) High concurrency : Infinispan Directory Provider: Lucene : Error loading metadata for index file

[ https://issues.jboss.org/browse/ISPN-8980?page=com.atlassian.jira.plugin.... ]
Rohit Singh edited comment on ISPN-8980 at 3/22/18 1:34 PM:
------------------------------------------------------------
Do you suggest to remove the property 'hibernate.search.default.locking_strategy'?
As per our understanding for *'Infinispan'* as directory provider, it is suggested to use *'SINGLE'* as *'hibernate.search.default.locking_strategy'*.
Moreover, as this is a standalone (non-clustered) env, setting locking_strategy as SINGLE or NONE shouldn't be different?
