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

Laurence Tratt: What Factors Explain the Nature of Software?
tratt.netdegree 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.
I conclude that there are two ways of constructing a software design: One way is to make it so simple that there are obviously no deficiencies, and the other way is to make it so complicated that there are no obvious deficiencies. The first method is far more difficult. It demands the same skill, devotion, insight, and even inspiration as the... See more
It does everything I want a word processing program to do and it doesn't do anything else. I don't want any help. I hate some of these modern systems where you type up a lowercase letter and it becomes a capital. I don't want a capital, if I'd wanted a capital, I would have typed the capital.

The beauty of finished software
In a world where constant change is the norm, finished software —a software you can use forever with no unneeded change —provides a breath of fresh air. It’s a reminder that reliability, consistency, and user satisfaction can coexist in the realm of software development.
The "Painless" data migration
- Another challenge was to incorporate the above changes for the existing data i.e. increasing the number of shards and defining a custom routing key for each of the document. The existing index had close to 33 MN documents at the time of the change
- Given that the routing key and the number of shards needed to changes, a
Improving query performance in ElasticSearch at scale
In Elasticsearch, these partitions are known as shards . Each node of the Elasticsearch cluster can serve queries independently for the partition it manages, thereby increasing query throughput.

The choice of the routing key in our case was a combination of the unique identifier (UUID) and type of the primary participant of each event in a calendar. This choice was made based on the querying patterns of the consuming application and to maintain a degree of uniqueness.
