Abstract: An accelerator or system including an accelerator can include an input interface to receive input data to be compressed and user application parameters for invocation of compression. The accelerator can include circuitry to identify a compression algorithm from configuration data provided with the input data. The user application parameters may not include parameters specifying entropy thresholds for compression of the input data. The circuitry can generate headers specific to the compression algorithm. The circuitry can generate uncompressed data blocks comprising blocks of the input data and corresponding headers. The circuitry can determine whether to provide the uncompressed data blocks or compressed data blocks based at least in part on entropy of the input data. Other methods, systems, and apparatuses are described.

Abstract: Examples described herein are generally directed to backing up and restoring of container clusters. According to an example, the conventional tight coupling between namespaces and tenants is eliminated by providing within a container platform a tenant abstraction for each tenant of the container platform that shares resources of a container cluster. The tenant abstraction for a given tenant includes information indicative of a subset of namespaces of the container cluster assigned to the given tenant. Responsive to receipt via a user interface of the container platform of a request to backup a particular tenant of the container platform: the container platform determines the subset of namespaces assigned to the particular tenant; and for each namespace, causes a namespace-level backup/recovery tool to backup object data for the namespace within a backup location, and backup data associated with persistent volume claims for each unit of cluster replication within the namespace.
