According to one or more embodiments of the present invention, a computer-implemented method includes creating a hybrid index for a multi-zone data storage system in which a first zone has data that is organized for transaction processing, and a second zone that has data organized for analytic processing. Each index entry in the hybrid index includes an index key including an equality column, a begin-timestamp column, and a tuple-sequence-number column. The method further includes building an index run to be included in the hybrid index, the index run includes multiple index entries. An index run is created by selecting columns by scanning data blocks from the first zone, computing tuple-sequence-number values for the index entries to be included in the hybrid index, and sorting the index entries according to a predetermined order using the columns to be included in the index run.

Indexing for evolving large-scale datasets in multi-master hybrid transactional and analytical processing systems

A method of delegating work of a computer program across a mixed computing environment is provided. The method includes: performing on one or more processors: allocating a container structure on a first context; delegating a new operation to a second context based on the container; receiving the results of the new operation; and storing the results in the container.

Methods and systems for delegating work objects across a mixed computer environment

A method of linking a computer program across a mixed computing environment is provided. The method includes, performing on one or more processors: identifying signatures of elements of the computer program; loading a plurality of modules of the computer program; and linking the plurality of modules using the signatures of the elements.

Methods and systems for linking objects across a mixed computer environment

A method of debugging a computer program across a mixed computing environment is provided. The method includes attaching a first debug module to a first program module of the computer program, where the first program module is operating on a first node; attaching a second debug module to a second program module of the computer program, where the second program module operating a second node of a different computer architecture; and initiating debug functions of at least one of the first debug module and the second debug module through a distant linker.

Methods and systems for interactive debugging in a mixed computer environment

A computing environment and techniques are provided for processing work out of order in one or more processing contexts. The processing techniques include: determining, for a processing context having an associated stack of waiting resources, whether a last-in listed resource in the stack of waiting resource is available, and if so, resuming processing of a suspended unit of work requiring the last-in listed resource; and determining, otherwise, whether an out of order execution unit of work is available for processing in the context, and if so, processing the out of order execution unit of work while the suspended unit of work awaits the last-in listed resource. Out of order execution units of work can be processed in order from a regular unit of work queue, or out of order from an out of order unit of work queue of a processing context.
