Abstract: A time series database system receives a request from a user device for first time series data within a first time range, the first time series data being a subset of second time series data within a second time range, the second time series data being stored in a persistent storage. The system determines whether all of the first time series data is stored in a memory. The system retrieves the second time series data from the persistent storage if all of the first time series data is not stored in the memory. The system stores the second time series data, excluding any part of the second time series data associated with a current time period, into the memory. The system causes the first time series data, being a subset of the second time series data retrieved from the persistent storage, to be outputted to the user device.
