Class MongoDBTransientStore

java.lang.Object
org.nuxeo.ecm.core.mongodb.transientstore.MongoDBTransientStore
All Implemented Interfaces:
TransientStore, TransientStoreProvider
public class MongoDBTransientStore extends Object implements TransientStoreProvider
Transient Store optimized for MongoDB, using a blob provider for binaries. It can replace the KeyValueBlobTransientStore implementation, it uses the same configuration.

A MongoDB collection is created per store, the name is prefixed by "transient.". If not provided the blob provider is created using a default configuration with "transient_" prefix that gives the required transient property.

The storage format is the following: 

 { "_id" : $KEY, "completed" : false, "ttl" : ISODate("2022-11-17T12:10:16.568Z"),
   "params" : { "chunked" : "false" } },
   "blobs" : [ { "key" : ..., "mimetype" : ..., "encoding" : ..., "filename" : ..., "length" : NumberLong(131984), "digest" : ... } ],
   "blobSize" : NumberLong(131984), "blobCount" : 1 }
The total size of the storage is computed with an aggregation on the blobSize property.
