Abstract: Apparatus, systems, and methods may operate to receive time-based reservation requests for predefined resource environments comprising resource types that include hardware, software, and data, among others. Additional activities may include detecting a conflict between at least one of the resource types in a first one of the predefined resource environments and at least one of the resource types in a second one of the predefined resource environments, and resolving the conflict in favor of the first one of the predefined resource environments by reserving additional resource elements in a cloud computing architecture and/or reserving a less capable version of the second one of the predefined resource environments. Additional apparatus, systems, and methods are disclosed.

Abstract: A data base system buffers incoming records according to destination in the disk or non-volatile memory. The data is compressed and transferred to disk when sufficient data has been accumulated for a particular disk destination. Techniques for compressing the compression dictionary as well as the data stream are described.

Abstract: The invention relates to a system for maintaining a log of incoming records for a database system. Seek points are inserted into the compressed data log in a manner that allows recovery to start from a specified point without a need for decompressing earlier portions of the log. The initial block of data is used as the compression dictionary. A new compression sequence using the same initial compression dictionary is started at each seek point.
