Re: Question about deserialize raw janusgraph/Cassandra data

Rafael Fernandes <luizr...@...>

Hi there,
Don't think there is better documentation other than this:
I did try to create my own version of an Object serializer once but I just reverted my changes and used ByteArraySerializer instead, a lot faster to unmarshall its state.

You may wanna have a look at this (org.janusgraph.graphdb.database.serialize.attribute.ObjectSerializer) or any org.janusgraph.graphdb.database.serialize.attribute.* really.
Those are the OOB implementations available, as simple as it gets, those are just marshall/unmarshall serializers.

Per my experience, those are enough for you and uber, but if you guys really wanna give it a shot, this is where you should start.
but give ByteArray a shot, it is super fast.

for those who don't know what I'm talking about, just set a"stateAsByte", something.makeByteArray());
than you can rebuild your Object by getting it back new Something( (byte[])"stateAsByte") ).

hope this helps,
Rafael Fernandes

Is there any document about how the data is serialized in Cassandra? We'd like to convert those raw data back to original form.
