Extension point store

In component org.nuxeo.ecm.core.transientstore.TransientStorageComponent

Documentation

Allow to declare a transient store inside Nuxeo. The store is identified by a name and the descriptor has several parameters :

    <store name="microStore">
        <!--  a store that can not store anything  -->
        <targetMaxSize>0</targetMaxSize>
        <absoluteMaxSize>0</absoluteMaxSize>
    </store>

The store tag supports 2 attributes:

name, that is used to identify the store
class, that should reference an implementation of the TransientStoreProvider interface (will default to SimpleTransientStore))

Nested configuration elements are :

targetMaxSize : target size that ideally should never be exceeded
absoluteMaxSize : size that must never be exceeded
firstLevelTTL : TTL in minutes of the first level cache
secondLevelTTL : TTL in minutes of the first level cache
