Cloud Bigtable V2 Client - Class Type (2.16.0)

Reference documentation and code samples for the Cloud Bigtable V2 Client class Type.

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") .
