摘要： A system and method for synchronously building a Ziv-Lempel dictionary during online insert processing. In one embodiment the invention includes a method for processing information that includes the steps of initiating a process for adding data to a data object including a table and determining if a predetermined condition exists for triggering the creation of a compression dictionary. The compression dictionary is then created if the predetermined condition exists. Once created, the dictionary may then be inserted into the data object.
摘要翻译：一种用于在线插入处理期间同步构建Ziv-Lempel字典的系统和方法。在一个实施例中，本发明包括一种处理信息的方法，该方法包括以下步骤：启动用于向包括表格的数据对象添加数据的过程，并且确定是否存在用于触发压缩字典的创建的预定条件。如果存在预定条件，则创建压缩词典。创建后，可将字典插入到数据对象中。

摘要： Techniques are described for data redistribution in a database system. Embodiments store a first set of receiver location identifiers mapped to a document identifier, the first set of receiver location identifiers assigned to a first set of receiver locations storing relational data referencing the document identifier. Embodiments further store a second set of receiver location identifiers mapped to the document identifier, the second set of receiver location identifiers assigned to a second set of receiver locations storing document data corresponding to the document identifier referenced by the relational data. Sender index keys are received separately from the relational data and the document data, the sender index keys referencing the document identifier and containing sender location identifiers. Embodiments determine, from the first set of receiver location identifiers and the second set of receiver location identifiers, which receiver location identifiers are mapped to the document identifier referenced by the sender index keys. The sender location identifiers are then replaced with the determined receiver location identifiers.
