Timestamp

Elastic Stack Elasticsearch

Hi guys,

I would like to add a creation date to every JSON document that I add
to the index.
How would I do that?

Thanks,

Andre

try
curl -XPOST 'http://localhost:9200/index/type' -d '{"create":'$
(date)'}'

You will need to add the timestamp yourself. We can add a special field, something like _timestamp that gets automatically added by elasticsearch, the problem with that is the fact that you will need to make sure the different machines in the cluster are sync'ed time wise.

Weiwei's example,

C:\elasticsearch-0.16.2\bin>curl -XPOST http://localhost:9200/twitter/user/dean
-d "{"user": "dean", "mydate" : "$(date)"}

is not working for, the index shows

{ "_index": "twitter", "_type": "user", "_id": "dean", "_score": 1,
"_source": { "user": "dean", "mydate": "$(date)" } }

Any ideas?

He ment that you will pass the date itself, preferable as an ISO format. Its not too difficult to add a timestamp field, as long as clocks are in sync. I think there is already an issue for that.

Ah, ok thanks.

What about a scripting feature in the input JSON? Do you think this
makes sense?

In what sense? One thing to note is that elasticsearch pull parse the json, there is no in memory representation of it. Things that munge the json before being indexed on elasticsearch is possible, but the implementation will require building an in memory representation of it, which will cost more.
