Store function
A function that specifies how to save the contents of a relation to external storage.
Often, load and store functions are implemented by the same type. For example,
PigStorage
, which loads data from delimited text files, can store data in the same
format.
Pig comes with a collection of built-in functions, a selection of which are listed in
Table 16-7
. The complete list of built-in functions, which includes a large number of
standard math, string, date/time, and collection functions, can be found in the documenta-
tion for each Pig release.
