public BigtableOptions.Types.Encoding Encoding { get; set; }
The encoding mode of the values when the type is not STRING.
Acceptable encoding values are:
TEXT: indicates values are alphanumeric text strings.
BINARY: indicates values are encoded using HBase Bytes.toBytes
family of functions. This can be overridden for a specific column
by listing that column in columns and specifying an encoding for it.
The field name to use for this column in the document. The name has to
match the pattern [a-zA-Z0-9][a-zA-Z0-9-_]*.
If not set, it is parsed from the qualifier bytes with best effort.
However, due to different naming patterns, field name collisions could
happen, where parsing behavior is undefined.
public BigtableOptions.Types.Type Type { get; set; }
The type of values in this column family.
The values are expected to be encoded using HBase Bytes.toBytes
function when the encoding value is set to BINARY.
