Elasticsearch index as a key/object storage

Elastic Stack Elasticsearch
1

Hello,
one of my index doesn't need any searching. All I need there is just to get
document's source by ID. Document is a free structure, could have any kind
of fields which I don't know upfront.
Could you please help me with mapping? Strangely, I couldn't find any way
to say: don't index my document no matter structure it would be, just store
it with some ID.
Thanks in advance,
Eugene

Hey,
You should do the following:

  • Disable dynamic mapping when you create the index (index.mapper.dynamic
    == 0)
  • Enable storing of the _source

That should be it. You will the need to use the GET API to access.

Best Regards,
Paul

Thank you Paul.
Just wanted to share an example for somebody who would have same question
later:

Here how you create such index:

curl -XPUT 'http://localhost:9200/MyIndexName/' -d '
{
"index": {
"mapper": {
"dynamic": false
},
"number_of_shards": 5,
"number_of_replicas": 1
}
}'

Correct me if I'm wrong, but looks like it works.
Thanks,
Eugene

I'd consider setting the "enabled" property on the default mapping
instead:

curl -XPUT 'http://127.0.0.1:9200/my_index/?pretty=1' -d '
{
"mappings" : {
"default" : {
"enabled" : false
}
}
}
'
