UIDSequencer based on Key/Value Store

A new KeyValueStoreUIDSequencer is available, to store sequences in a key/value store. The store is the same for all sequencers, but they are using different keys, prefixed by the sequencer name. It can be used by doing for example: <extension target= "org.nuxeo.ecm.core.uidgen.UIDGeneratorService" point= "sequencers" > <sequencer name= "uidgen" class= "org.nuxeo.ecm.core.uidgen.KeyValueStoreUIDSequencer" default= "true" /> </extension> <extension target= "org.nuxeo.runtime.ConfigurationService" point= "configuration" > <!-- this is an example, "sequence" is already the default --> <property name= "nuxeo.uidseq.keyvaluestore.name" > sequence </property> </extension> Assuming the following configuration to define a suitable key/value store, for example: <extension target= "org.nuxeo.runtime.kv.KeyValueService" point= "configuration" > <store name= "sequence" class= "org.nuxeo.ecm.core.mongodb.kv.MongoDBKeyValueStore" > <property name= "collection" > sequence </property> </store> </extension>
