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.
