I have an Elasticsearch index with hundreds of millions of documents that is used mostly for the "get by id" queries.
I consider adding a route to documents when indexing. The route will be a random number from 0 to 9.
Later this route will be in an URL with the document id, it that will be used to get the document. Currently I have only document ids in the URLs but plan to add routes as well. The new URL will look like this https://tarta.ai/ j/ [route] /[doc id].
I'm wondering will it decrease the time needed to find a document in the index? My suggestion is that Elasticsearch in this case won't look for a document in all the shards but instead will look only in the shards with this particular route.
- index size is 110gb.
- the number of docs is 36m but we're adding hundreds of thousands every day.
- 5 shards.
- 16GB RAM and 2 core vm with a 1t SSD.
