It uses "open addressing" with quadratic reprobing to resolve
collisions.

This op creates a mutable hash table, specifying the type of its keys and
values. Each value must be a scalar. Data can be inserted into the table using
the insert operations. It does not support the initialization operation.

| ## Args ||
|---|---|
| `empty_key` | A `Tensor`. The key used to represent empty key buckets internally. Must not be used in insert or lookup operations. |
| `deleted_key` | A `Tensor`. Must have the same type as `empty_key`. |
| `value_dtype` | A [`tf.DType`](https://www.tensorflow.org/versions/r2.13/api_docs/python/tf/dtypes/DType). Type of the table values. |
| `container` | An optional `string`. Defaults to `""`. If non-empty, this table is placed in the given container. Otherwise, a default container is used. |
| `shared_name` | An optional `string`. Defaults to `""`. If non-empty, this table is shared under the given name across multiple sessions. |
| `use_node_name_sharing` | An optional `bool`. Defaults to `False`. |
| `value_shape` | An optional [`tf.TensorShape`](https://www.tensorflow.org/versions/r2.13/api_docs/python/tf/TensorShape) or list of `ints`. Defaults to `[]`. The shape of each value. |
| `initial_num_buckets` | An optional `int`. Defaults to `131072`. The initial number of hash table buckets. Must be a power to 2. |
| `max_load_factor` | An optional `float`. Defaults to `0.8`. The maximum ratio between number of entries and number of buckets before growing the table. Must be between 0 and 1. |
| `name` | A name for the operation (optional). |
