Abstract

A method and system for coordinating reclamation of space in hard disks/partitions in a stream processing graph is disclosed. The method involves monitoring one or more hard disks/partitions for determining space. Accordingly, the one or more hard disks/partitions are notified for freeing up the space.

Method and System for Coordinating Reclamation of Space in Hard Disks /Partitions in

a Stream Processing Graph

Disclosed is a method and system for coordinating reclamation of space in hard disks/partitions in a stream processing graph. The stream processing graph includes one or more components running on one or more hard disks/partitions. The method involves monitoring the one or more hard disks/partitions for determining space. The one or more hard disks/partitions are monitored by a Disk Usage Server (DUS). Further, each hard disk/partition uses one disk usage command.

While monitoring the one or more hard disks/partitions, if the space is determined to be low, DUS notifies each component of the one or more components to free a predefined amount of space. Furthermore, a space quota of a hard disk/partition may be configured by specifying an amount of space available on the hard disk/partition. In a scenario, if a component of the one or more components requires a free space, then the free space may be provided by the one or more components. However, if the space is determined to fall below a critical limit, DUS notifies each component of the one or more components to free all the available space. In a scenario, upon determining a fall in the space below a critical limit, the one or more components may be allowed to continue processing because the processing results in freeing up of space.

Consider a scenario wherein one or more hosts may use same hard disk/pa...
