digest

public String digest()

Description copied from interface: DrillTableSelection

The digest of the selection represented by the implementation. The selections that accompany Tables can modify the contained dataset, e.g. a file selection can restrict to a subset of the available data and a format selection can include options that affect the behaviour of the underlying reader. Two scans will end up being considered identical during logical planning if their digests are the same so selection implementations should override this method so that exactly those scans that really are identical (in terms of the data they produce) have matching digests.

Specified by:

digest in interface DrillTableSelection

Returns:

this selection's digest, normally a string built from its properties.
