Shard in computing
WebbEach index, shard, segment and field has overheadedit. Every index and every shard requires some memory and CPU resources. In most cases, a small set of large shards uses fewer resources than many small shards. Segments play a big role in a shard’s resource usage. Most shards contain several segments, which store its index data. WebbShards. The partitioned data chunks are called logical shards. The machine that stores the logical shard is called a physical shard or database node. A physical shard can contain …

Webb14 jan. 2024 · Each of these sets of rows is called a shard. These shards are distributed across multiple server nodes (containers, VMs, bare-metal) in a shared-nothing architecture. This ensures that the shards do not get bottlenecked by the compute, storage and networking resources available at a single node.
