Abstract: Systems and methods are described for registering a new column in an existing table on a distributed file system as a partition. In response to receiving a request to add a new column to a selected table, a new table may be created that includes all fields of the selected table, the new column, and a new partition, and the selected table may be renamed within the distributed file system. A view may then be created that points to data in the new table and the renamed selected table, the created view being a virtual table that receives and processes queries. All data from the renamed selected table may be transferred the new table. When the transfer is complete, the new table may be renamed to an original name of the selected table, and any data received after the renaming may be included in the renamed new table.

Abstract: This invention comprises of a special class of directional gesture patterns, a computational system for spontaneous recognition of continuous gesture pattern inputs and a methodology to map the gesture patterns to characters, symbols and control functions. The gesture path in two dimensional coordinate systems can be captured by any touch surface device or camera based position tracking technologies like WII remote, Microsoft XBOX or gyroscopic devices to track motion. The special class of directional gesture patterns called mayek may be composed with a sequence of gesture segments. The directions of the adjacent gesture segments of the mayek patterns may be assigned alternately from two different direction subsets. For example, one of the direction subset may be {north, south, east, west} and the other direction subset may be {north-east, north-west, south-east, south-west}. The gesture recognition system may recognize the patterns entered non-stop in running writing style.
