Abstract: LOB cache swapping is reduced by multi-LOB writing. Under multi-LOB writing, information that tracks changes made by a database transaction to multiple LOBs is retained in a LOB staging buffer after one or more LOB switches. Thus, at commit time, changes to multiple LOBs in a column may be staged in the LOB staging cache, thereby enabling the changes to be made in contiguous data blocks for all the multiple LOBs. Storing LOBs in the same column in this way improves clustering, thereby improving database performance. In addition, LOBs inserted or updated in the same database transaction are often related and accessed together within database transactions and/or query accesses. Clustering the LOB content of such related LOBs allows the LOBs to be accessed more efficiently.

Abstract: Object store management operations within compute-centric object stores are provided herein. An exemplary method may include transforming an object storage dump into an object store table by a table generator container, wherein the object storage dump includes at least objects within an object store that are marked for deletion, transmitting records for objects from the object store table to reducer containers, such that each reducer container receives object records for at least one object, the object records comprising all object records for the at least one object, generating a set of cleanup tasks by the reducer containers, and executing the cleanup tasks by a cleanup agents.

Abstract: Systems and methods for providing a compute-centric object store. An exemplary method may include receiving a request to perform a compute operation on at least a portion of an object store from a first user, the request identifying parameters of the compute operation, assigning virtual operating system containers to the objects of the object store from a pool of virtual operating system containers. The virtual operating system containers may perform the compute operation on the objects according to the identified parameters of the request. The method may also include clearing the virtual operating system containers and returning the virtual operating system containers to the pool.

Abstract: Instruction set architectures for compute-centric object stores. An exemplary method may include receiving a request from a user, the request identifying parameters of a compute operation that is to be executed against one or more objects in a distributed object store, generating a set of tasks from the request that comprise instructions for a daemon, locating the one or more objects within the distributed object store, the one or more objects being stored on a physical node. The method includes providing the set of tasks to a daemon, the daemon controlling execution of the compute operation by a virtual operating system container based upon the set of tasks, and storing an output of the virtual operating system container in the distributed object store.
