    摘要: Methods and systems are described that involve usage of dictionaries for compressing a large set of variable-length string values with fixed-length integer keys in column stores. The dictionary supports updates (e.g., inserts of new string values) without changing codes for existing values. Furthermore, a shared-leaves approach is described for indexing such a dictionary that compresses the dictionary itself while offering access paths for encoding and decoding.

    摘要: Methods and apparatus, including computer program products, are provided for providing for processing calculation plans. In one aspect, there is provided a computer-implemented method. The method may include generating a calculation plan including a plurality of nodes; determining whether at least one of the nodes includes a function node; and compiling the function node into executable code to enable execution of the plurality of nodes including the function node at the database. Related apparatus, systems, methods, and articles are also described.
