The road to Infinispan 10 (Alpha1)

Dear all,

Today we are releasing 10.0.0.Alpha1 and 9.4.2.Final.

Infinispan 9.4.2.Final comes with a number of bug fixes and some small additional features:

• ISPN-9655 REST Access Log headers
• ISPN-8144 & ISPN-9661 Cross-Site replication statistics
• ISPN-9708 Expose the executor services through JMX
• ISPN-9732 Local iteration optimization with write behind is valid for non shared stores
• ISPN-9717 Fix Integer overflow for lifespan and maxIdle

We have begun working on what will become Infinispan 10. As with all new major releases, this will come with a number of important changes.

• New Server
  We are working on a new lightweight server, currently dubbed ServerNG, which will supersede the current WildFly-based offering. The new server will have a smaller disk and memory footprint, a new RESTful admin interface, improved security. It will still use familiar components (Elytron for security, Narayana for transactions, etc) but we hope that the installation and usability experience will be most improved. A dedicated blog post will describe in detail what is coming.
• Long-term Storage Format
  The persistent storage format will be changed so that it will be easier to transparently make changes to it without requiring further exporters/importers.
• Non-blocking listeners
  The listener implementation will be replaced with a non-blocking implementation.
• Asynchronous CacheLoader/Store
  Store operations will be ran in another thread to provide non blocking for main threads
• Improved statistics
  Infinispan statistics have been traditionally over-simplistic, offering mostly basic averages for writes and reads. We are going to implement percentiles on a histogram as well as recording tracing information so that you will be able to know how much time is being spent in the various subsystems (clustering, persistence, etc.)
• New API
  The current Infinispan API, based around Java's ConcurrentHashMap design, does not offer the flexibility required to support modern reactive designs as well as the various extensions we've added over the years (counters, multimaps, etc). We are therefore working on a new modern API design which we will be describing with a number of blog posts in the near future.
• Agroal JDBC Connection Pool
  We are replacing the JDBC connection pool implementation with Agroal.
• Kubernetes Operators
  Operators are all the rage in the Kubernetes world, and we are working on an Infinispan Operator which will take care of managing and monitoring the health of an Infinispan cluster, handle scale up/scale down safely, perform upgrades and more.

Infinispan 10.0.0.Alpha1 is the first release from our development branch. It currently includes the following features on top of what is in 9.4.2.Final:

• ISPN-9666 Agroal JDBC Connection pool
• ISPN-9688 Internal REST server modularization

Please report any issues in our issue tracker and join the conversation in our Zulip Chat to shape up our next release.

Infinispan 9.0.0.Alpha1 is out!

Dear Infinispan community,

it is with great pleasure that we are announcing the release of Infinispan 9.0.0.Alpha1 the first release of the Infinispan 9 series.

We plan to do many exciting things in Infinispan 9.x, and this release is just one of many stepping-stones that will get us there. Here's what's included with Alpha1:

• Graceful clustered shutdown / restart with persistent state
• The REST cache store has a shiny new Netty-based backend, courtesy of Antoine Toulme
• and many, many bugfixes: consult our issue tracker for a list of things we have fixed. 

A new major release is also the moment to peform some "spring-cleaning" (pun intended):

• We've removed Spring 3.x support
• We've removed our home-brew map/reduce implementation. By now you should be using the wonderful Streams-based API instead which are much nicer and provide better performance
• We've dropped our custom NotifyingListeners in favour of Java's standard CompletableFuture

Infinispan 8.0.0.Alpha2

Dear Infinispan community,

it is with great pleasure that we are announcing the release of Infinispan 8.0.0.Alpha2 as we continue forward.

This release brings a few very useful features:

• second batch for size-based eviction: sized based eviction has been updated to work when storeAsBinary is enabled or if the cache only contains primitive wrapper types (Integer, Long.. etc), Strings or byte[].
• entry iterator over HotRod: it is now possible to iterate over all the entries in a cache even in distributed mode using HotRod.  This provides full consistency guarantees under a rehash event (node goes up or down) and batches data to help prevent memory issues on the client.
• non-indexed query over indexed cache with compatiblity
• first batch for infinispan core threading changes: we are improving our thread utilization significantly with the 8.0 release cycle and we already have reduced transport thread usage and added a configurable thread pool for async operations to prevent internal thread pool exhaustion.  There will be even more enhancements for this in future releases!
• and many many bugfixes, consult our issue tracker for a list of things we have fixed.

Don't forget to also check-out our roadmap to see the things we plan to get done during the 8.0 cycle.

Infinispan 8.0.0.Alpha1

Dear Infinispan community,

it is with great pleasure that we are announcing the release of Infinispan 8.0.0.Alpha1. This is the first release of Infinispan that requires Java 8 to compile and run. We have great plans in store for our Java 8 API, and this is the first step in getting there. Don't worry, however: we intend to maintain backwards compatibility for both configuration and API.

This release brings some highly requested features:

• the introduction of size-based eviction, i.e. the ability to set a maximum amount of heap used by a cache. Please note that this requires enabling storeAsBinary. This feature has only been tested with HotSpot, and other JVMs (e.g. IBM J9) will not behave as expected. We welcome any improvements you can give us to help with alternate JVMs.
• the ability to run non-indexed queries on indexed data: this means that if you issue a query with predicates which involve non-indexed fields, Infinispan will still be able to execute the query. In the future we intend to also add support for hybrid queries, i.e. queries which can take advantage of indexed fields but which also need to discern on non-indexed ones.
• and many many bugfixes, consult our issue tracker for a list of things we have fixed. 

We have also removed asynchronous marshalling which never worked quite right, and also imposed several limitations on applications. Good riddance !

Don't forget to also check-out our roadmap to see the things we plan to get done during the 8.0 cycle.

Infinispan 6.0.0.Alpha4 out with new CacheLoader/CacheWriter API!

Infinispan 6.0.0.Alpha4 is now with a few very important changes, particularly around cache stores. We've completely revamped the cache store/loader API to align it a bit better with JSR-107 (old CacheStore has become CacheWriter) and to simplify creation of new implementations. The new CacheLoader and CacheWriter should help implementors focus on the important operations and reduce the coding time. We've also created AdvancedCacheLoader and AdvancedCacheWriter in order to separate for bulk operations or purging for those implementations that wish optionally implement them. Expect a blog post from Mircea in the next few days providing many more details on this topic.

This new Infinispan version comes with other important goodies:

• Rolling upgrades of a Infinsipan REST cluster
• Support for Cache-Control headers for REST operations
• Remote querying server modules and Hot Rod client update
• REST and LevelDB stores added to Infinispan Server
• KeyFilters can now be applied to Cache listeners
• Allow Cache listener events to be invoked only on the primary data owner

Faster file cache store (no extra dependencies!) in 6.0.0.Alpha1

As announced yesterday by Adrian, the brand new Infinispan 6.0.0.Alpha1 release contains a new file-based cache store which needs no extra dependencies. This is essentially a replacement of the existing FileCacheStore which didn't perform as expected, and caused major issues due to the number of files it created.

The new cache store, contributed by a Karsten Blees (who also contributed an improved asynchronous cache store), is called SingleFileCacheStore and it keeps all data in a single file. The way it looks up data is by keeping an in-memory index of keys and the positions of their values in this file. This design outperforms the existing FileCacheStore and even LevelDB based JNI cache store.

The classic case for a file based cache store is when you want to have a cache with a cache store available locally which stores data that has overflowed from memory, having exceeded size and/or time restrictions. We ran some performance tests to verify how fast different cache store implementations could deal with reading and writing overflowed data, and these are the results we got (in Ks):

• FileCacheStore: 0.75k reads/s, 0.285k writes/s
• LevelDB-JNI impl: 46k reads/s, 15.2k writes/s
• SingleFileCacheStore: 458k reads/s, 137k writes/s

The difference is quite astonishing but as already hinted, this performance increase comes at a cost. Having to maintain an index of keys and positions in the file in memory has a cost in terms of extra memory required, and potential impact on GC. That's why the SingleFileCacheStore is not recommended for use cases where the keys are too big.

In order to help tame this memory consumption issues, the size of the cache store can be optionally limited, providing a maximum number of entries to store in it. However, setting this parameter will only work in use cases where Infinispan is used as a cache. When used as a cache, data not present in Infinispan can be recomputed or re-retrieved from the authoritative data store and stored in Infinispan cache. The reason for this limitation is because once the maximum number of entries is reached, older data in the cache store is removed, so if Infinispan was used as an authoritative data store, it would lead to data loss which is not good.

Existing FileCacheStore users might wonder: what is it gonna happen to the existing FileCacheStore? We're not 100% sure yet what we're going to do with it, but we're looking into some ways to migrate data from the FileCacheStore to the SingleFileCacheStore. Some interesting ideas have already been submitted which we'll investigate in next Infinispan 6.0 pre-releases.

So, if you're a FileCacheStore user, give the new SingleFileCacheStore a go and let us know how it goes! Switching from one to the other is easy :)

Cheers,

Galder

Infinispan 6.0.0.Alpha1 is out!

Dear Infinispan community,

We're proud to announce the first Alpha release of Infinispan 6.0.0. Starting with this release, Infinispan license is moving to the terms of the Apache Software Licence version 2.0.

Besides increased stability (about 30 bug fixes) this release also brings several new features:

• A more efficient FileCacheStore implementation (courtesy Karsten Blees)
  
• A new set of usage and performance statistics developed within the scope of the CloudTM project
• A new (experimental) marshaller for Hot Rod based on protobuf, which will be primarily used by the upcoming remote querying feature. Since this has reuse potential in other projects it was promoted to an independent project named protostream under the Infinispan umbrella
  

For a complete list of features and fixes included in this release please refer to the release notes.
