A thread factory (implementing java.util.concurrent.ThreadFactory). The "name" attribute is the bean name of the created thread factory. The optional "priority" attribute may be used to specify the thread priority of created threads. The optional "group-name" attribute specifies the name of a the thread group to create for this thread factory. The "thread-name-pattern" is the template used to create names for threads. The following patterns may be used: %% - emit a percent sign %t - emit the per-factory thread sequence number %g - emit the global thread sequence number %f - emit the factory sequence number %i - emit the thread ID %G - emit the thread group name

Name Type Default Description

blocking-bounded-queue-thread-pool*

A thread pool executor with a bounded queue. Such a thread pool has a core size and a queue with an upper bound. When a task is submitted, if the number of running threads is less than the core size, a new thread is created. Otherwise, the task is placed in queue. If too many tasks are allowed to be submitted to this type of executor, an out of memory condition may occur. The "name" attribute is the bean name of the created executor. The "max-threads" attribute must be used to specify the maximum thread pool size. The "core-threads" attribute defines the number of threads to keep in the pool. The nested "keepalive-time" element may used to specify the amount of time that pool threads should be kept running when idle; if not specified, threads will run until the executor is shut down. The "thread-factory" element specifies the bean name of a specific thread factory to use to create worker threads.

Name Type Default Description
name string
thread-factory string
max-threads int
core-threads int

lock-timeout long 240000 Infinispan uses a distributed lock to maintain a coherent transaction log during state transfer or rehashing, which means that only one cache can be doing state transfer or rehashing at the same time. This constraint is in place because more than one cache could be involved in a transaction. This timeout controls the time to wait to acquire a distributed lock.

isolation
NONE No locking isolation will be performed. This is only valid in local mode. In clustered mode, READ_COMMITTED will be used instead.
READ_UNCOMMITTED Unsupported. Actually configures READ_COMMITTED
READ_COMMITTED Read committed is an isolation level that guarantees that any data read is committed at the moment it is read. However, depending on the outcome of other transactions, successive reads may return different results
REPEATABLE_READ Repeatable read is an isolation level that guarantees that any data read is committed at the moment it is read and that, within a transaction, successive reads will always return the same data.
SERIALIZABLE Unsupported. Actually configures REPEATABLE_READ
READ_COMMITTED Sets the cache locking isolation level. Infinispan only supports READ_COMMITTED or REPEATABLE_READ isolation level.

lifespan long -1 Maximum lifespan of a cache entry, after which the entry is expired cluster-wide, in milliseconds. -1 means the entries never expire.

compatibility?

The cache compatibility mode configuration.

Name Type Default Description
marshaller string A marshaller to use for compatibility conversions.

store-as-binary?

Configures the cache to store data in binary format.

Controls whether when stored in memory, keys and values are stored as references to their original objects, or in a serialized, binary format. There are benefits to both approaches, but often if used in a clustered mode, storing objects as binary means that the cost of serialization happens early on, and can be amortized. Further, deserialization costs are incurred lazily which improves throughput. It is possible to control this on a fine-grained basis: you can choose to just store keys or values as binary, or both.
Name Type Default Description
keys boolean true Specify whether keys are stored as binary or not. Enabled by default if the "enabled" attribute is set to true.
values boolean true Specify whether values are stored as binary or not. Enabled by default if the "enabled" attribute is set to true.

persistence?

Configures the cache's persistence layer.

Name Type Default Description
passivation boolean false If true, data is only written to the cache store when it is evicted from memory, a phenomenon known as 'passivation'. Next time the data is requested, it will be 'activated' which means that data will be brought back to memory and removed from the persistent store. This gives you the ability to 'overflow' to disk, similar to swapping in an operating system. If false, the cache store contains a copy of the contents in memory, so writes to cache result in cache store writes. This essentially gives you a 'write-through' configuration. Defaults to false.

versioning?

Controls whether entries are versioned. Versioning is necessary, for example, when using optimistic transactions in a clustered environment, to be able to perform write-skew checks.

Name Type Default Description
scheme
SIMPLE A simple versioning scheme that is cluster-aware
NONE Don't version entries
NONE The scheme to use when versioning entries. Can be either SIMPLE or NONE. Defaults to NONE

data-container?

READ_COMMITTED Read committed is an isolation level that guarantees that any data read is committed at the moment it is read. However, depending on the outcome of other transactions, successive reads may return different results
REPEATABLE_READ Repeatable read is an isolation level that guarantees that any data read is committed at the moment it is read and that, within a transaction, successive reads will always return the same data.

READ_COMMITTED Sets the cache locking isolation level. Infinispan only supports READ_COMMITTED or REPEATABLE_READ isolation level.

Configures the cache to store data in binary format.

Controls whether when stored in memory, keys and values are stored as references to their original objects, or in a serialized, binary format. There are benefits to both approaches, but often if used in a clustered mode, storing objects as binary means that the cost of serialization happens early on, and can be amortized. Further, deserialization costs are incurred lazily which improves throughput. It is possible to control this on a fine-grained basis: you can choose to just store keys or values as binary, or both.
Name Type Default Description

Next time the data is requested, it will be 'activated' which means that data will be brought back to memory and removed from the persistent store. This gives you the ability to 'overflow' to disk, similar to swapping in an operating system. If false, the cache store contains a copy of the contents in memory, so writes to cache result in cache store writes. This essentially gives you a 'write-through' configuration. Defaults to false.
