In-memory ingestion for highly available distributed time-series databases

Abstract:

Techniques for -memory ingestion for highly available distributed time-series databases are described. A method of in-memory ingestion may include obtaining, by a host of a time series database, time series data from one or more electronic devices, the time series database including a plurality of portions of the time series database spread across a plurality of hosts, the plurality of portions of the time series database including at least one hot portion and a plurality of cold portions, storing the time series data in a volatile storage location associated with the hot portion on the host, detecting an event to store the time series data associated with the hot portion to a non-volatile storage location on the host, and storing the time series data associated with the hot portion to the non-volatile storage location.
