Abstract: Techniques to reduce database fragmentation are disclosed. In various embodiments, an indication is received to store an attribute value for an entity that has a row or other entry in a first database table, wherein the first database table does not have a column for the attribute. It is determined that the value corresponds to a mapped value that is associated with not having an entry in a separate, second database table configured to store the attribute. Entries are made in the second database table only for values of the attribute other than the mapped value. Application level software code is configured to associate absence of a row in the second database table with the mapped value for the attribute.

Abstract: Some embodiments provide a method for migrating data from a first database to a second database. The data is susceptible to change at the first database before all of the data is migrated to the second database and is available for access through the second database. The method transfers segments of data incrementally from the first database to the second database and generates a first digital signature for each transferred segment. The method identifies a set of transferred segments that have been modified in the first database before the data is available for access through the second database by generating a second digital signature for each transferred segment in the set and comparing the second digital signature for the segments with the first digital signature for the segments. The method transfers the modified segments from the first database to the second database in order to replace the previously transferred segments.

Abstract: Techniques for identifying video and/or audio content are presented. An identification management component (IMC) groups users determined to be at least potentially be watching the same content based on first content fingerprints associated with respective content viewed by the users on communication devices, and a defined matching criterion. IMC facilitates identifying the content associated with the group of users based on first content fingerprints associated with the group of users and first reference content fingerprints. IMC receives a second content fingerprint associated with a communication device of a user in the group, sends the second content fingerprint to a third-party identification component for comparison with second reference content fingerprints, and receives content identification information in response.

Abstract: Systems and methods for presenting CRM data. Users may configure what to display on a custom report and how to arrange and display the content (e.g., size, color, theme), so that they can visualize the CRM data the way they want. A data visualization interface may be used to generate the custom report, and may use HTML to specify the CRM data to be displayed and their location on the custom report according to user configuration. The data visualization interface may use JavaScript for specifying the objects and fields users want to query to obtain the CRM data to fill up the custom report. An API may communicate with the JavaScript in the data visualization interface and then query data and objects in the CRM to get a result set. The API may be a unified API which may work across multiple platforms and query various types of database, e.g., iOS, Windows, and the browser for Salesforce online. Users may edit the CRM data displayed in the custom report.

Abstract: The subject technology receives a first transaction, the first transaction to be executed on linearizable storage. The subject technology assigns, prior to performing a read operation, a first read version to the first transaction, the first read version indicating a first version of the linearizable storage, the first read version corresponding to a particular timestamp of a current time. The subject technology performs the read operation from the first transaction on a table in a database. The subject technology determines a first commit version identifier corresponding to first data resulting from the read operation. The subject technology proceeds to perform a particular write operation from the first transaction. The subject technology determines that the first commit version identifier fails to match a second commit version identifier corresponding to a second transaction. The subject technology aborts the particular write operation from the first transaction.

Abstract: Techniques herein use in-memory column vectors to process data that is external to a database management system (DBMS) and logically join the external data with data that is native to the DBMS. In an embodiment, a computer maintains a data dictionary for native data that is durably stored in an DBMS and external data that is not durably stored in the DBMS. From a client through a connection to the DBMS, the computer receives a query. The computer loads the external data into an in-memory column vector that resides in random access memory of the DBMS. Based on the query and the data dictionary, the DBMS executes a data join of the in-memory column vector with the native data. To the client through said connection, the computer returns results of the query based on the data join.
