Is there a way of using identity/autonumber ids in ES similar to a
traditional relational database?
I have an index called post_index with "post" documents and I want to
assign unique numeric ids to them (1, 2, 3..). Is there an easy way of
doing this or should I manage the generation of the ids somewhere else?
When you send a document without ID, ES will give you one.
It's not a counter but a hashcode.

If you really need an auto increment style number instead of the auto
generated ids, you can use the _version technique describe
here http://blogs.perl.org/users/clinton_gormley/2011/10/elasticsearchsequence---a-blazing-fast-ticket-server.html
Thanks you both. I had noticed the generated hashcode, but I really need an
auto increment style number, so I will give it a try. Very helpful link.

Hi Daniel, do you use the _version technique now? Is it working well for
you?
BTW: I created a node.js module https://github.com/analog-nico/es-sequence for
it.

hi, i tried ur module, it is useful & nice. But why sequence version
increments by 100? is it blank updating 100 times?

For better performance the lib fetches 100 ids at a time and caches those.
This way elasticsearch is only queried every 100th get call.
Do you call init before every get call? This way the cache would be cleared
each time. init only needs to be called once on startup.
