Sentinel indicating that the default fill value should be used.

This sentinel exists because conventional values used to convey "defaultness" like `None` or
`"auto"` are ambiguous when specifying the fill value parameter of a Zarr array.
The value `None` is ambiguous because it is a valid fill value for Zarr V2
(resulting in `"fill_value": null` in array metadata).
A string like `"auto"` is ambiguous because such a string is a valid fill value for an array
with a string data type.
This sentinel lies outside the space of valid fill values, which means it can
unambiguously express that the default fill value should be used.

        Notes

        Slices with step > 1 are supported, but slices with negative step are not.

        For arrays with a structured dtype, see Zarr format 2 for examples of how to use
        fields

        Currently the implementation for __getitem__ is provided by
        [`vindex`][zarr.Array.vindex] if the indexing is pure fancy indexing (ie a
        broadcast-compatible tuple of integer array indices), or by
        [`set_basic_selection`][zarr.Array.set_basic_selection] otherwise.

        Effectively, this means that the following indexing modes are supported:

           - integer indexing
           - slice indexing
           - mixed slice and integer indexing
           - boolean indexing
           - fancy indexing (vectorized list of integers)

        For specific indexing options including outer indexing, see the
        methods listed under Related.

            >>> import numpy as np
            >>> data = np.arange(100).reshape(10, 10)

            array([[10, 11, 12, 13, 14, 15, 16, 17, 18, 19],

    Parameters
    ----------
    store : StoreLike
        StoreLike object to open. See the
        [storage documentation in the user guide][user-guide-store-like]
        for a description of all valid StoreLike values.
    data : Array | array-like
        The array to copy.
    write_data : bool, default True
        Whether to copy the data from the input array to the new array.
        If `write_data` is `False`, the new array will be created with the same metadata as the
        input array, but without any data.
    name : str or None, optional
        The name of the array within the store. If `name` is `None`, the array will be located
        at the root of the store.
    chunks : tuple[int, ...] or Sequence[Sequence[int]] or "auto" or "keep", optional
        Chunk shape of the array.
        Following values are supported:

        - "auto": Automatically determine the chunk shape based on the array's shape and dtype.
        - "keep": Retain the chunk grid of the data array if it is a zarr Array.
        - tuple[int, ...]: A tuple of integers representing the chunk shape (regular grid).
        - Sequence[Sequence[int]]: Per-dimension chunk edge lists (rectilinear grid).
          Rectilinear chunk grids are experimental and must be explicitly enabled
          with `zarr.config.set({'array.rectilinear_chunks': True})` while the
          feature is stabilizing.

        If not specified, defaults to "keep" if data is a zarr Array, otherwise "auto".
    shards : tuple[int, ...], optional
        Shard shape of the array.
        Following values are supported:

        - "auto": Automatically determine the shard shape based on the array's shape and chunk shape.
        - "keep": Retain the shard shape of the data array if it is a zarr Array.
        - tuple[int, ...]: A tuple of integers representing the shard shape.
        - None: No sharding.

        If not specified, defaults to "keep" if data is a zarr Array, otherwise None.
    filters : Iterable[Codec] | Literal["auto", "keep"], optional
        Iterable of filters to apply to each chunk of the array, in order, before serializing that
        chunk to bytes.

        For Zarr format 3, a "filter" is a codec that takes an array and returns an array,
        and these values must be instances of [`zarr.abc.codec.ArrayArrayCodec`][], or a
        dict representations of [`zarr.abc.codec.ArrayArrayCodec`][].

        For Zarr format 2, a "filter" can be any numcodecs codec; you should ensure that the
        order of your filters is consistent with the behavior of each filter.

        The default value of `"keep"` instructs Zarr to infer `filters` from `data`.
        If that inference is not possible, Zarr will fall back to the behavior specified by `"auto"`,
        which is to choose default filters based on the data type of the array and the Zarr format specified.
        For all data types in Zarr V3, and most data types in Zarr V2, the default filters are the empty tuple `()`.
        The only cases where default filters are not empty is when the Zarr format is 2, and the
        data type is a variable-length data type like [`zarr.dtype.VariableLengthUTF8`][] or
        [`zarr.dtype.VariableLengthUTF8`][]. In these cases, the default filters is a tuple with a
        single element which is a codec specific to that particular data type.

        To create an array with no filters, provide an empty iterable or the value `None`.
    compressors : Iterable[Codec] or "auto" or "keep", optional
        List of compressors to apply to the array. Compressors are applied in order, and after any
        filters are applied (if any are specified) and the data is serialized into bytes.

        For Zarr format 3, a "compressor" is a codec that takes a bytestream, and
        returns another bytestream. Multiple compressors may be provided for Zarr format 3.

        For Zarr format 2, a "compressor" can be any numcodecs codec. Only a single compressor may
        be provided for Zarr format 2.

        Following values are supported:

        - Iterable[Codec]: List of compressors to apply to the array.
        - "auto": Automatically determine the compressors based on the array's dtype.
        - "keep": Retain the compressors of the input array if it is a zarr Array.

        If no `compressors` are provided, defaults to "keep" if data is a zarr Array, otherwise "auto".
    serializer : dict[str, JSON] | ArrayBytesCodec or "auto" or "keep", optional
        Array-to-bytes codec to use for encoding the array data.
        Zarr format 3 only. Zarr format 2 arrays use implicit array-to-bytes conversion.

        Following values are supported:

        - dict[str, JSON]: A dict representation of an `ArrayBytesCodec`.
        - ArrayBytesCodec: An instance of `ArrayBytesCodec`.
        - "auto": a default serializer will be used. These defaults can be changed by modifying the value of
          `array.v3_default_serializer` in [`zarr.config`][zarr.config].
        - "keep": Retain the serializer of the input array if it is a zarr Array.

    fill_value : Any, optional
        Fill value for the array.
        If not specified, defaults to the fill value of the data array.
        Pass `None` explicitly to use the default scalar of the data type
        (Zarr format 3) or a null fill value (Zarr format 2) instead.
    order : {"C", "F"}, optional
        The memory order of the array (default is "C").
        For Zarr format 2, this parameter sets the memory order of the array.
        For Zarr format 3, this parameter is deprecated, because memory order
        is a runtime parameter for Zarr format 3 arrays. The recommended way to specify the memory
        order for Zarr format 3 arrays is via the `config` parameter, e.g. `{'config': 'C'}`.
        If not specified, defaults to the memory order of the data array.
    zarr_format : {2, 3}, optional
        The zarr format to use when saving.
        If not specified, defaults to the zarr format of the data array.
    attributes : dict, optional
        Attributes for the array.
        If not specified, the source Zarr array's attributes are deep-copied so
        nested containers are independent. Deeply nested attributes can raise
        `RecursionError` during copying even if they can be stored and reopened;
        the threshold depends on Python's recursion limit and the current call stack.
        Pass an empty dict to create the array with no attributes.
    chunk_key_encoding : ChunkKeyEncoding, optional
        A specification of how the chunk keys are represented in storage.
        For Zarr format 3, the default is `{"name": "default", "separator": "/"}}`.
        For Zarr format 2, the default is `{"name": "v2", "separator": "."}}`.
        If not specified and the data array has the same zarr format as the target array,
        the chunk key encoding of the data array is used.
    dimension_names : Iterable[str | None] | None
        The names of the dimensions (default is None).
        Zarr format 3 only. Zarr format 2 arrays should not use this parameter.
        If not specified, defaults to the dimension names of the data array.
    storage_options : dict, optional
        If using an fsspec URL to create the store, these will be passed to the backend implementation.
        Ignored otherwise.
    overwrite : bool, default False
        Whether to overwrite an array with the same name in the store, if one exists.
    config : ArrayConfig or ArrayConfigLike, optional
        Runtime configuration for the array.

    Returns
    -------
    AsyncArray

    Parameters
    ----------
    store_path : StorePath
        StorePath instance. The path attribute is the name of the array to initialize.
    shape : tuple[int, ...]
        Shape of the array.
    dtype : ZDTypeLike
        Data type of the array.
    chunks : tuple[int, ...], optional
        Chunk shape of the array.
        If not specified, default are guessed based on the shape and dtype.
    shards : tuple[int, ...], optional
        Shard shape of the array. The default value of `None` results in no sharding at all.
    filters : Iterable[Codec] | Literal["auto"], optional
        Iterable of filters to apply to each chunk of the array, in order, before serializing that
        chunk to bytes.

        For Zarr format 3, a "filter" is a codec that takes an array and returns an array,
        and these values must be instances of [`zarr.abc.codec.ArrayArrayCodec`][], or a
        dict representations of [`zarr.abc.codec.ArrayArrayCodec`][].

        For Zarr format 2, a "filter" can be any numcodecs codec; you should ensure that the
        order of your filters is consistent with the behavior of each filter.

        The default value of `"auto"` instructs Zarr to use a default based on the data
        type of the array and the Zarr format specified. For all data types in Zarr V3, and most
        data types in Zarr V2, the default filters are empty. The only cases where default filters
        are not empty is when the Zarr format is 2, and the data type is a variable-length data type like
        [`zarr.dtype.VariableLengthUTF8`][] or [`zarr.dtype.VariableLengthUTF8`][]. In these cases,
        the default filters contains a single element which is a codec specific to that particular data type.

        To create an array with no filters, provide an empty iterable or the value `None`.
    compressors : Iterable[Codec] | Literal["auto"], optional
        List of compressors to apply to the array. Compressors are applied in order, and after any
        filters are applied (if any are specified) and the data is serialized into bytes.

        The default value of `"auto"` instructs Zarr to use a default of [`zarr.codecs.ZstdCodec`][].

        To create an array with no compressors, provide an empty iterable or the value `None`.
    serializer : dict[str, JSON] | ArrayBytesCodec | Literal["auto"], optional
        Array-to-bytes codec to use for encoding the array data.
        Zarr format 3 only. Zarr format 2 arrays use implicit array-to-bytes conversion.

        The default value of `"auto"` instructs Zarr to use a default codec based on the data type of the array.
        For most data types this default codec is [`zarr.codecs.BytesCodec`][].
        For [`zarr.dtype.VariableLengthUTF8`][], the default codec is [`zarr.codecs.VlenUTF8Codec`][].
        For [`zarr.dtype.VariableLengthBytes`][], the default codec is [`zarr.codecs.VlenBytesCodec`][].
    fill_value : Any, optional
        Fill value for the array.
    order : {"C", "F"}, optional
        The memory order of the array (default is "C").
        For Zarr format 2, this parameter sets the memory order of the array.
        For Zarr format 3, this parameter is deprecated, because memory order
        is a runtime parameter for Zarr format 3 arrays. The recommended way to specify the memory
        order for Zarr format 3 arrays is via the `config` parameter, e.g. `{'config': 'C'}`.
        If no `order` is provided, a default order will be used.
        This default can be changed by modifying the value of `array.order` in [`zarr.config`][zarr.config].
    zarr_format : {2, 3}, optional
        The zarr format to use when saving.
    attributes : dict, optional
        Attributes for the array.
    chunk_key_encoding : ChunkKeyEncodingLike, optional
        A specification of how the chunk keys are represented in storage.
        For Zarr format 3, the default is `{"name": "default", "separator": "/"}}`.
        For Zarr format 2, the default is `{"name": "v2", "separator": "."}}`.
    dimension_names : Iterable[str], optional
        The names of the dimensions (default is None).
        Zarr format 3 only. Zarr format 2 arrays should not use this parameter.
    overwrite : bool, default False
        Whether to overwrite an array with the same name in the store, if one exists.
    config : ArrayConfigLike or None, default=None
        Configuration for this array.
        If  `None`, the default array runtime configuration will be used. This default
        is stored in the global configuration object.

    Returns

    Parameters
    ----------
    store : StoreLike
        StoreLike object to open. See the
        [storage documentation in the user guide][user-guide-store-like]
        for a description of all valid StoreLike values.
    name : str or None, optional
        The name of the array within the store. If `name` is `None`, the array will be located
        at the root of the store.
    shape : ShapeLike, optional
        Shape of the array. Must be `None` if `data` is provided.
    dtype : ZDTypeLike | None
        Data type of the array. Must be `None` if `data` is provided.
    data : np.ndarray, optional
        Array-like data to use for initializing the array. If this parameter is provided, the
        `shape` and `dtype` parameters must be `None`.
    chunks : tuple[int, ...] | Sequence[Sequence[int]] | Literal["auto"], default="auto"
        Chunk shape of the array.
        If chunks is "auto", a chunk shape is guessed based on the shape of the array and the dtype.
        A nested list of per-dimension edge sizes creates a rectilinear grid.
        Rectilinear chunk grids are experimental and must be explicitly enabled
        with `zarr.config.set({'array.rectilinear_chunks': True})` while the
        feature is stabilizing.
    shards : tuple[int, ...], optional
        Shard shape of the array. The default value of `None` results in no sharding at all.
    filters : Iterable[Codec] | Literal["auto"], optional
        Iterable of filters to apply to each chunk of the array, in order, before serializing that
        chunk to bytes.

        For Zarr format 3, a "filter" is a codec that takes an array and returns an array,

        and these values must be instances of [`zarr.abc.codec.ArrayArrayCodec`][], or a
        dict representations of [`zarr.abc.codec.ArrayArrayCodec`][].

        For Zarr format 2, a "filter" can be any numcodecs codec; you should ensure that the
        order of your filters is consistent with the behavior of each filter.

        The default value of `"auto"` instructs Zarr to use a default based on the data
        type of the array and the Zarr format specified. For all data types in Zarr V3, and most
        data types in Zarr V2, the default filters are empty. The only cases where default filters
        are not empty is when the Zarr format is 2, and the data type is a variable-length data type like
        [`zarr.dtype.VariableLengthUTF8`][] or [`zarr.dtype.VariableLengthUTF8`][]. In these cases,
        the default filters contains a single element which is a codec specific to that particular data type.

        To create an array with no filters, provide an empty iterable or the value `None`.
    compressors : Iterable[Codec], optional
        List of compressors to apply to the array. Compressors are applied in order, and after any
        filters are applied (if any are specified) and the data is serialized into bytes.

        For Zarr format 3, a "compressor" is a codec that takes a bytestream, and
        returns another bytestream. Multiple compressors may be provided for Zarr format 3.
        If no `compressors` are provided, a default set of compressors will be used.
        These defaults can be changed by modifying the value of `array.v3_default_compressors`
        in [`zarr.config`][zarr.config].
        Use `None` to omit default compressors.

        For Zarr format 2, a "compressor" can be any numcodecs codec. Only a single compressor may
        be provided for Zarr format 2.
        If no `compressor` is provided, a default compressor will be used.
        in [`zarr.config`][zarr.config].
        Use `None` to omit the default compressor.
    serializer : dict[str, JSON] | ArrayBytesCodec, optional
        Array-to-bytes codec to use for encoding the array data.
        Zarr format 3 only. Zarr format 2 arrays use implicit array-to-bytes conversion.
        If no `serializer` is provided, a default serializer will be used.
        These defaults can be changed by modifying the value of `array.v3_default_serializer`
        in [`zarr.config`][zarr.config].
    fill_value : Any, optional
        Fill value for the array.
    order : {"C", "F"}, optional
        The memory order of the array (default is "C").
        For Zarr format 2, this parameter sets the memory order of the array.
        For Zarr format 3, this parameter is deprecated, because memory order
        is a runtime parameter for Zarr format 3 arrays. The recommended way to specify the memory
        order for Zarr format 3 arrays is via the `config` parameter, e.g. `{'config': 'C'}`.
        If no `order` is provided, a default order will be used.
        This default can be changed by modifying the value of `array.order` in [`zarr.config`][zarr.config].
    zarr_format : {2, 3}, optional
        The zarr format to use when saving.
    attributes : dict, optional
        Attributes for the array.
    chunk_key_encoding : ChunkKeyEncodingLike, optional
        A specification of how the chunk keys are represented in storage.
        For Zarr format 3, the default is `{"name": "default", "separator": "/"}}`.
        For Zarr format 2, the default is `{"name": "v2", "separator": "."}}`.
    dimension_names : Iterable[str], optional
        The names of the dimensions (default is None).
        Zarr format 3 only. Zarr format 2 arrays should not use this parameter.
    storage_options : dict, optional
        If using an fsspec URL to create the store, these will be passed to the backend implementation.
        Ignored otherwise.
    overwrite : bool, default False
        Whether to overwrite an array with the same name in the store, if one exists.
        If `True`, all existing paths in the store will be deleted.
    config : ArrayConfigLike, optional
        Runtime configuration for the array.
    write_data : bool
        If a pre-existing array-like object was provided to this function via the `data` parameter
        then `write_data` determines whether the values in that array-like object should be
        written to the Zarr array created by this function. If `write_data` is `False`, then the
        array will be left empty.
