Repartitioning data in a distributed computing system
Methods, systems, and apparatus for allocating, by a source of one or more sources, a segment of a data file of a transient memory for exclusive access by the source, the transient memory being a distributed in-memory file system that supports remote direct memory access; writing, by the source, data from an initial partition to one or more blocks within the allocated segment of the data file, wherein a portion of the initial partition is written to a first block of the one or more blocks; publishing, by the source, the segment of the data file of the transient memory to be accessible for reading by one or more sinks; and reading by a particular sink of the one or more sinks, a particular block of the published segment of the data file of the transient memory, wherein the particular block is associated with the particular sink.
