If you are using the Official ElasticSearch Python library (Docs), and you want to create an index:
1
2
3
4
5
6
7
|
doc = {
"something": "123a",
"somethingelse": "456b",
"timestamp": datetime.now(),
"history": []
}
es.index(index="someindex", doc_type="somedoctype", id="someid", body=doc)
|
You can append items to the history each time, instead of overriding them, like this:
1
2
3
4
5
6
7
8
9
10
|
es.update(index="someindex", doc_type="somedoctype", id="someid",
body={
"script" : {
"source": "ctx._source.history.addAll(params.history)",
"lang": "painless",
"params" : {
"history" : ["item1","item2"]
}
}
})
|
This uses scripted updates in Elasticsearch, for appending to an array.
