As a Cloud Native Computing Foundation (CNCF) incubating project, OTel aims to provide unified sets of vendor-agnostic libraries and APIs — mainly for collecting data and transferring it somewhere. This is common in on-premises or hybrid deployments, where time series data and tags are transmitted to the cloud.

Redis Cluster is the native sharding implementation available within Redis that allows you to automatically distribute your data across multiple nodes without having to rely on external tools and utilities. A given key is mapped to one of these slots, and the hash slot for a key is computed as: HASH_SLOT = CRC16(key) mod 16384.
