Abstract
Methods, systems, and computer-readable media for heat balancing in a distributed time-series database are disclosed. A time-series database stores time-series data using database clusters. A plurality of leases for tiles representing spatial and temporal partitions of the time-series data are assigned to a first storage node. The time-series database determines that a heat metric for the first storage node has exceeded a threshold. The time-series database determines respective heat metrics for additional storage nodes including a second storage node. The time-series database selects the second storage node based (at least in part) on the respective heat metrics. The time-series database reassigns one or more of the leases from the first storage node to the second storage node. The second storage node stores elements of the time-series data into the plurality of database clusters in one or more tiles associated with the one or more reassigned leases.
