Abstract: The disclosed embodiments disclose techniques for managing a distributed cache in a cloud-based distributed computing environment (CBDCE). During operation, an instance of a data processing layer service (DPL) receives a data request from a client that specifies an address and an operation for a target data block. The DPL instance uses these to determine a first cache instance of the distributed cache that is assigned to cache a metadata entry that links the address with a data block fingerprint for the target data block. The DPL instance then uses the data block fingerprint and the cache mapping to determine a second cache instance that is assigned to store the target data block, and then accesses the second cache instance to complete the operation for the target data block.

During operation, the system uses a distributed database to track the status of the CBDCE to ensure the ongoing stability and scalability of the CBDCE. Upon receiving a request that is associated with the configuration of the CBDCE, a service accesses CBDCE status information from the distributed database to respond to the request.
