Abstract
Systems and methods for reslicing data in a representation of a relational database are disclosed. In one embodiment, the database includes a representation including a first slice. The database system creates a plurality of new slice and to create a plurality of write queues. The database system copies units of data in the first slice to the new slices according to a distribution function. The distribution function determines, for each unit of data in the first slice, one of the new slices into which to copy the unit of data. The database system asynchronously writes one or more actions of a set of one or more asynchronous database transactions to the first slice when copying the data in the first slice to the new slices. The database asynchronously enqueues the one or more actions of the set of asynchronous database transactions in the write queues according to the distribution function.
