I'm using Neo4j 2.0.1 with Cypher over the Batch REST API.

I took a look at the document and had the following comments.  Keep in mind I have no experience with the internals of Neo4j and only moderate experience with using Neo4j (exclusively the REST endpoint using Cypher as the query language).  I thought I would share my thoughts just in case any of it might prove useful.

Gzip

I didn’t see any mention of support for Gzip encoding the results.  Since the result sets for Neo4j queries can be large, there would be significant benefit to supporting compression.  I expected to see the following specified on each of the requests:

Accept-Encoding:  gzip, compress
