WebRedis Streams is an implementation of the immutable log that uses radix trees as the underlying data structure. Each stream entry is identified by a timestamp and can contain an arbitrary set of field-value pairs. Entries of the same stream can have different fields, but Redis is able to compress multiple events in a row that share the same schema. WebFor details on why, note that streams are implemented as radix trees. Simply put, Redis streams provide highly efficient inserts and reads. See each command's time complexity for the details.
