Reference documentation and code samples for the Cloud Bigtable V2 Client class Map.
A mapping of keys to values of a given type.
Values of typeMapare stored in aValue.array_valuewhere each entry
is anotherValue.array_valuewith two elements (the key and the value,
in that order).
Normally encoded Map values won't have repeated keys, however, clients are
expected to handle the case in which they do. If the same key appears
multiple times, thelastvalue takes precedence.
