tf.raw_ops.LMDBDataset

Creates a dataset that emits the key-value pairs in one or more LMDB files.

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 .mdb suffix.

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.

filenames A Tensor of type string. A scalar or a vector containing the name(s) of the binary file(s) to be read.
output_types A list of tf.DTypes that has length >= 1.
output_shapes A list of shapes (each a tf.TensorShape or list of ints) that has length >= 1.
name A name for the operation (optional).

A Tensor of type variant.
