Provisioning timestamp-based storage units for time series data
Provisioning timestamp-based storage units for time series data is described. A time series database system determines a remaining time period for a first storage unit to reach a storage capacity, the first storage unit storing first data with a first minimum timestamp. The time series database system provisions a second storage unit if the remaining time period for the first storage unit satisfies the provisioning threshold and stores second data with a second minimum timestamp to the second storage unit. The time series database system dispatches a query for third time series data to any storage unit if a time span from a minimum timestamp to a maximum timestamp associated with the storage unit includes at least part of a time range associated with the third time series data. The time series database system responds to the query for the third time series data based on dispatching the query.
1. A system for provisioning timestamp-based storage units for time series data, the system comprising:
one or more processors; and

determine, by a time series database system, a remaining time period for a first storage unit to reach a storage capacity and whether the remaining time period satisfies a provisioning threshold, the first storage unit storing first time series data associated with a first minimum timestamp;
provision, by the time series database system, a second storage unit in response to a determination that the remaining time period for the first storage unit satisfies the provisioning threshold;
store, by the time series database system, second time series data to the provisioned second storage unit, the second time series data being associated with a second minimum timestamp;
dispatch, by the time series database system, a query for third time series data to any storage unit in response to a determination that a time span from a minimum timestamp to a maximum timestamp associated with the storage unit comprises at least part of a time range associated with the third time series data; and
respond, by the time series database system, to the query for the third time series data based on dispatching the query.
2. The system of claim 1 , wherein determining the remaining time period is based on a remaining storage capacity and a diminishing storage capacity rate for the first storage unit.
3. The system of claim 1 , wherein the provisioning threshold is based on at least one of a historical provisioning time, a projected provisioning time, and a worst case provisioning time.
4. The system of claim 1 , wherein at least one of the first storage unit and the second storage unit comprises a corresponding plurality of storage devices.

provision, by the time series database system, a second storage unit in response to a determination that the remaining time period for the first storage unit satisfies the provisioning threshold;
store, by the time series database system, second time series data to the provisioned second storage unit, the second time series data being associated with a second minimum timestamp;
dispatch, by the time series database system, a query for third time series data to any storage unit in response to a determination that a time span from a minimum timestamp to a maximum timestamp associated with the storage unit comprises at least part of a time range associated with the third time series data; and
respond, by the time series database system, to the query for the third time series data based on dispatching the query.
