  - CONCURRENCY_LEVEL

  - ISOLATION_LEVEL

public static final AttributeDefinition<Boolean> WRITE_SKEW_CHECK
```
- Method Detail
  - concurrencyLevel
```
public int 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.
  - supportsConcurrentUpdates
```
@Deprecated
public boolean supportsConcurrentUpdates()
```
    Deprecated.
    this option is always true and cannot be modified since version 5.3
    
    This option applies to non-transactional caches only (both clustered and local): if set to true(default value) the cache keeps data consistent in the case of concurrent updates. For clustered caches this comes at the cost of an additional RPC, so if you don't expect your application to write data concurrently, disabling this flag increases performance.
  - isolationLevel
```
public IsolationLevel isolationLevel()
```
    Cache isolation level. Infinispan only supports READ_COMMITTED or REPEATABLE_READ isolation levels. See http://en.wikipedia.org/wiki/Isolation_level for a discussion on isolation levels.
  - lockAcquisitionTimeout
```
public long lockAcquisitionTimeout()
```
    Maximum time to attempt a particular lock acquisition
  - lockAcquisitionTimeout
```
public LockingConfiguration lockAcquisitionTimeout(long timeout)
```
  - useLockStriping
```
public boolean 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.
  - writeSkewCheck
```
@Deprecated
public boolean writeSkewCheck()
```
    Deprecated.
    since 9.0.
    
    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.
  - attributes

public boolean equals(Object obj)
```
    Overrides:
    
    equals in class Object
  - hashCode
```
public int hashCode()
```
    Overrides:
    
    hashCode in class Object
