Linear doesn’t have metrics goals - the founder thinks setting specific metric goals can lead them astray. Product goals should be about how we solve our customers’ problems better.
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 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.
