- The number of partitions is fixed at the time of the index creation. Each partition is an indivisible chunk of data which can grow in size but not be split into smaller chunks. As the data grows, more nodes may be added to the cluster, but the number of partitions which eventually move to the newer nodes are limited (Fig 3)
- In some sense, as the
Improving query performance in ElasticSearch at scale
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
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.
Replication lag occurs when there is a delay between a write operation being executed on the primary (leader) node and the same operation being replicated to the secondary (follower) nodes.
Replication lag is a basic issue in leader-based replication systems that are made for better availability, scalability, and faster response times by spreading out read operations across replicas in different locations.
In most companies, activity is driven by the org chart. That’s how decisions are made, communicated, and acted on. That’s why it’s hard to scale as a company grows. Deep org charts give structure to huge hierarchies of people, but they’re not great for executing on projects.
