tf.raw_ops.LMDBDataset( filenames, output_types, output_shapes, name=None )
The Lightning Memory-Mapped Database Manager, or LMDB, is an embedded binary key-value database. This dataset can read the contents of LMDB database files, the names of which generally have the
Each output element consists of a key-value pair represented as a pair of scalar string
Tensors, where the first
Tensor contains the key and the second
Tensor contains the value.
LMDB uses different file formats on big- and little-endian machines.
LMDBDataset can only read files in the format of the host machine.
