Nonstop Timeouts and Behaviors

enabled – Enables ("true" DEFAULT) or disables ("false") the ability of a cache to execute certain actions after a Terracotta client disconnects. This attribute is optional for enabling nonstop.

immediateTimeout – Enables ("true") or disables ("false" DEFAULT) an immediate timeout response if the Terracotta client detects a network interruption (the node is disconnected from the cluster). If enabled, this parameter overrides timeoutMillis, so that the option set in timeoutBehavior is in effect immediately.

timeoutMillis – Specifies the number of milliseconds an application waits for any cache operation to return before timing out. The default value is 30000 (thirty seconds). The behavior after the timeout occurs is determined by timeoutBehavior.

searchTimeoutMillis – Specifies the number of milliseconds an application waits for search operations to return before timing out. The default value is 30000 (thirty seconds). The behavior after the timeout occurs is determined by timeoutBehavior.

<nonstop> has one self-closing sub-element, <timeoutBehavior>. This sub-element determines the response after a timeout occurs (timeoutMillis expires or an immediate timeout occurs). The response can be set by the <timeoutBehavior>attribute type. This attribute can have one of the values listed in the following table:

Value	Behavior
exception	(DEFAULT) Throw NonStopCacheException. For more information about this exception, see When is NonStopCacheException Thrown?.
noop	Return null for gets. Ignore all other cache operations. Hibernate users may want to use this option to allow their application to continue with an alternative data source.
localReads	For caches with Terracotta clustering, allow inconsistent reads of cache data. Ignore all other cache operations. For caches without Terracotta clustering, throw an exception.
localReadsAndExceptionOnWrite	For caches with Terracotta clustering, allow inconsistent reads of cache data, and throw a NonStopCacheException for write operations. For caches without Terracotta clustering, throw an exception.
