Re: How to circumvent transaction cache?
My thoughts are:
1) As you said, you wanted to be able to disable the transaction cache so that you can read from database again. I have provided a solution here:

Hi Saurabh,
To be sure, in the valueMap(true) return value I see both the id token and an "id" property key appear (I am not even sure whether an "id" property key is allowed). Is this "id" property

- we are using index for looking up V in the graph
- observation is that for many vertices with the same index

Re: Driver's for java connectivity
Vinayak,
If your goal is simply to get your entire graph into a JSON-based format, you may want to consider GraphSON (http://tinkerpop.apache.org/docs/3.4.1/dev/io/#graphson).
