Unique Indexes and REST

[Nigel Small]

Hi chaps

We are currently working with unique indexes via the REST interface and it seems that we could do with a finer-grained level of control with regards to the operations available, particularly when batching up a number of requests.

Currently, we can quite happily call a "get_or_create" style operation which will return 201 if a node (or relationship) is indexed and 200 if it one already exists for that key-value pair. A desired alternative however would be to have a "create_or_fail" type operation which could return 201 or 400 instead. Importantly, this operation would stop the batch in progress and roll back the transaction.

Perhaps the URI could accept a flag something like:

POST http://localhost:7474/db/data/index/node/people?unique&fail_if_exists

WDYT?

Nigel,

uniqueness=create_or_fail will return either 200 or 409 (conflict)

this is available in 1.9 snapshot.

That's awesome, thanks a lot :-)
