    Abstract: Method, system, and computer program product are provided to guarantee no tuple loss and/or corruption in a real-time data streaming environment. In some embodiments, a stream of tuples is sent from an entry operator to downstream operator(s), and, at the entry operator, a mark is placed on each tuple in the stream of tuples. In an embodiment where the stream of tuples includes first, second, and subsequent tuple(s), for example, the mark may comprise a tuple-unique number and a tuple-data hash of data contained in the tuple, and the mark on the second and each subsequent tuple may further comprise a link-back hash associated with the immediately preceding tuple in the stream of tuples. In some embodiments, the link-back hash is used to check whether a tuple is lost or received out of order, and the tuple-data hash is used to check whether a received tuple is corrupt.

    Abstract: Techniques for cognitive interpretation of source code are provided. Metadata associated with a section of code in a software project is analyzed to determine a change history of the section of code. A plurality of discussions related to the section of code is evaluated, where each of the plurality of discussions occurred during a code review process. Further, a plurality of support records related to the section of code is analyzed. A sentiment score for the section of code is determined based on the associated metadata, the evaluation of the plurality of discussions, and the analysis of the plurality of support records. Additionally, a display color for the section of code is selected based on the sentiment score. Finally, generation of a graphical user interface (GUI) is facilitated, where the GUI displays the first display color in association with the first section of code.

    Abstract: A structured query language (SQL) query is configured to present a selected portion of a result set to a user interface. The selected portion of the result set can be based on an offset criteria appended to the SQL query. The offset criteria determines a location of a first presented instance of the selected portion of the result set. The offset criteria is configured to determine the location of the first presented instance of the selected portion of the result set independent of a number of instances appearing between a first instance of the result set and the first presented instance of the selected portion of the result set.

    Abstract: A respective volatility attribute associated with each of one or more tables of a computerized database is used in any of various aspects to (a) determine how table data is stored in a physical storage device; (b) regulate the use of a materialized query table using database table data; and/or (c) influence circumstances under which indexes are created or advised by database analytic software. Various optional additional uses of a volatility attribute to manage a database are disclosed. Preferably, database parameters are automatically monitored over time and database table volatility state is automatically determined and periodically adjusted.

    Abstract: Systems and methods for providing automatic fork protection including determining that a transaction having fork protection was included in a first block that was appended to a blockchain, that a hash of the first block was validated, that a consensus decision was made by validator nodes approving the first block for addition to the blockchain, that a second block was appended to the blockchain after the first block, that the second block comprises a hash that is not based on the first block, that the first block was on a first fork and the second block was on a second fork, that the blockchain was resolved in favor of the second fork, and that the transaction failed as a result of the blockchain being resolved in favor of the second fork. The method including compensating a party that submitted the failed transaction based on the fork protection.
