Pros
- The query speeds improve as, instead of instructing Elasticsearch to Get all the data matching... , you say Go there and get all the data matching... ( Fig 6 ). If you are querying data with multiple unique routing keys, this guarantees better or equivalent query performance as that of the default routing strategy (reducing the scatter and
Improving query performance in ElasticSearch at scale
degree of iteration in software development is inevitable. As soon as one accepts that logic, one must then also accept that software development will be subject to friction (i.e. unexpected inefficiencies). When I plan the future for a piece of software, I expect to encounter ongoing friction, and I try to allow for that. I remain astonished at how many organisations assume that a master plan for their software can be rigidly followed.
The formula in Fig 5 is one of the reasons why Elasticsearch does not allow the update of the number of primary shards post index creation. What the default routing guarantees is that the data will be uniformly distributed across the cluster which would reduce query hotspots when retrieving documents
