Type class
Type represents the type of data that is written to, read from, or stored
in Bigtable.
It is heavily based on the GoogleSQL standard to help maintain familiarity
and consistency across products and features. For compatibility with
Bigtable's existing untyped APIs, each Type includes an Encoding which
describes how to convert to or from the underlying data. Each encoding can
operate in one of two modes: - Sorted: In this mode, Bigtable guarantees
that Encode(X) <= Encode(Y) if and only if X <= Y. This is useful
anywhere sort order is important, for example when encoding keys. -
Distinct: In this mode, Bigtable guarantees that if X != Y then Encode(X) != Encode(Y). However, the converse is not guaranteed. For example, both
{'foo': '1', 'bar': '2'} and {'bar': '2', 'foo': '1'} are valid
encodings of the same JSON value. The API clearly documents which mode is
used wherever an encoding can be configured. Each encoding also documents
which values are supported in which modes. For example, when encoding INT64
as a numeric STRING, negative numbers cannot be encoded in sorted mode. This
is because INT64(1) > INT64(-1), but STRING("-00001") > STRING("00001").
