DISTRIBUTED CACHE AVAILABILITY DURING GARBAGE COLLECTION

摘要

Techniques are described herein for managing access to a distributed cache during garbage collection. When garbage collection is to be performed with respect to a node, the node may send a request to a data manager requesting to have an instance of data module(s) included in the node that are in a primary state placed in a secondary state. The data manager may change the state of the data module(s) to the secondary state. The data manager may change the state of another instance of the data module(s) that is included in another node to the primary state. When the garbage collection is complete with respect to the node, the node may send another request to the data manager requesting that the data module(s) that were placed in the secondary state be returned to the primary state. The data manager may return those data module(s) to the primary state.
