Does anyone know what the big disclaimer at the top of [https://www.elastic.co/blog/customizing-your-document-routing](https://www.elastic.co/blog/customizing-your-document-routing) means? I'm trying to transition from a one-index-per-user setup (which was killing me because of RAM usage) to a many-users-per-index setup. So routing is something I want to make sure I understand ... this article is very helpful, except it's explicitly warning not to trust it!! ---

I think that one of the reason is that you can not extract routing key from the doc anymore IIRC from 2.0. Apart from that, I still think routing is good. 🙂 ---

I studied the routing concept in the above mentioned link. But my need is totally different. I have three type of logs like Prepaid, Postpaid & CDMA. The traffic is little bit high (1200 per second from each). I mostly search based on the type. For that I neeeded routing. But I cant allocate only one shard per type as like in the manual. So I want to allocate 5 shards for postpaid and route all the postpaid traffic to the 5 shards and so on for others also. The routing is based on the path `/home/ES/POSTPAID/SMSCDR_POSTPAID_160518010000_10.80.41.70_RS1.log /home/ES/CDMA/SMSCDR_DEL_ATTEMPT_160518000000_10.80.41.68_RS3_1.log /home/ES/PREPAID/SMSCDR_PREPAID_160518220000_10.80.41.88_RS10.log` Allocate 5 shards for one type. Note: I cant maintain three indices for these three. I have indices based on the operator. Hope I am understandable.. ---

I don't believe you have another choice than building one index per type `prepaid`, `postpaid`and `cdma`. On the opposite you can totally send all documents for the same operator within the same shard using routing. ---

These are same in the performance??? `1 index with 30 shards 3 indexes with 10 shards each` ---

Searching in 30 shards, wherever they are in 30 indices / 1 shard or 1 index / 30 shards has the same cost. But remember that you want to use routing here. So basically you will search in 3 shards at most. ---
