just as an FYI there is a bug in the mongodb impl in the file
MongoDbDeltaCollection.java here...
129 @Override
130 public WaveletDeltaRecord getDeltaByEndVersion(long version) throws
IOException {
131 DBObject query = createWaveletDBQuery();
132
query.put(MongoDbDeltaStoreUtil.FIELD_TRANSFORMED_RESULTINGVERSION_VERSION,
version);
133
134 DBObject result = deltaDbCollection.findOne(query);
135
136 WaveletDeltaRecord waveletDelta = null;
137
138 if (result != null)
139 try {
*140 MongoDbDeltaStoreUtil.deserializeWaveletDeltaRecord(result);*
141 } catch (PersistenceException e) {
142 throw new IOException(e);
143 }
144 return waveletDelta;
145 }
that may cause issues, the deserialised record doesn't actually get
returned. Once I fixed the mongodb unit tests, I found it.
