Gremlin to cypher transpiler

[selva]

our system is currently aligned with apache tinkerpop gaph database
Due to critical business reason wanted to migrate it to Neo4j

we have used gremlin for graph traversal and approximately 10000 gremlin traversal queries(read intensive system) and impossible to translate each and every query to cypher .
It will lead to a very big change in the system , testing etc .

Hence we are looking for a gremlin to cypher converter library 

Could you please provide insights .

Thanks,
Selvaraj C

Hi,

Can you first check https://tinkerpop.apache.org/docs/current/reference/#neo4j-gremlin and see whether it meets your requirements?

Best wishes,    Marc

thanks Marc.
have checked it and doesnt work .
do we have any reference for building abstract syntax tree for gremlin query?

As of 3.5.0 there is an ANTLR grammar for Gremlin - perhaps that can be of some use:

https://github.com/apache/tinkerpop/blob/3.5.0/gremlin-language/src/main/antlr4/Gremlin.g4

It is still under development though - you may find patches where bits of Gremlin don't get fully processed by it. That said, it's tested against all the reference documentation and our gherkin test suite so it does have pretty good compatibility at this point.

hello，I want to know if you have any progress on this, as we are currently working on it too.

Looking forward to communicating with you very much.

Thanks,

Hello,

While there still isn't an official Gremlin to Cypher converter perhaps you could share any particular challenges you’ve encountered, and the gremlin community could help to figure out solutions for those challenges.

Thanks,

Andrea

In addition to what Andreas said, I would also share some examples of your Gremlin queries. Whether particular queries can be meaningfully converted at all, depends on the syntax features you use. Then you can compare the two paths to success.
