InfluxDB
Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.
Take a look at the Bytes crate. With it, one can buffer bytes into a BufMut, and send borrowed slices as Bytes. Once the Bytes are freed, the BufMut takes care of reusing the capacity. Several of the web server frameworks use this, so it's fairly mature.
