Documentation

            Defines the local, in-VM locking and concurrency characteristics of the cache.
          

Properties

This component is not nillable.

concurrencyLevel

Concurrency level for lock containers. Adjust this value according to the number of concurrent threads interacting with Infinispan. Similar to the concurrencyLevel tuning parameter seen in the JDK's ConcurrentHashMap.

Type:

xs:int

Use:

optional

Form:

unqualified

isolationLevel

Cache isolation level. Infinispan only supports READ_COMMITTED or REPEATABLE_READ isolation levels. See http://en.wikipedia.org/wiki/Isolation_level'>http://en.wikipedia.org/wiki/Isolation_level for a discussion on isolation levels.

Type:

tns:isolationLevel

Use:

optional

Form:

unqualified

lockAcquisitionTimeout

Maximum time to attempt a particular lock acquisition

Type:

xs:long

Use:

optional

Form:

unqualified

useLockStriping

If true, a pool of shared locks is maintained for all entries that need to be locked. Otherwise, a lock is created per entry in the cache. Lock striping helps control memory footprint but may reduce concurrency in the system.

Type:

xs:boolean

Use:

optional

Form:

unqualified

writeSkewCheck

This setting is only applicable in the case of REPEATABLE_READ. When write skew check is set to false, if the writer at commit time discovers that the working entry and the underlying entry have different versions, the working entry will overwrite the underlying entry. If true, such version conflict - known as a write-skew - will throw an Exception.

Type:

xs:boolean

Use:

optional

Form:

unqualified
