kartothek.core.urlencode module

kartothek.core.urlencode.decode_key(key)

Split a given key into its kartothek components {dataset_uuid}/{table}/{key_indices}/{filename}

Example

uuid/table/index_col=1/index_col=2/partition_label.parquet

Returns

• dataset_uuid (str)

• table (str)

• key_indices (list) – The already unquoted list of index pairs

• file_ (str) – The file name

kartothek.core.urlencode.quote(value)

Performs percent encoding on a sequence of bytes. if the given value is of string type, it will be encoded. If the value is neither of string type nor bytes type, it will be cast using the str constructor before being encoded in UTF-8.

kartothek.core.urlencode.quote_indices(indices: List[Tuple[str, str]]) → List[str]

Urlencode a list of column-value pairs and encode them as:

quote(column)=quote(value)

Parameters

indices – A list of tuples where each list entry is (column, value)

Returns

List with urlencoded column=value strings

Return type

List[str]

kartothek.core.urlencode.unquote(value)

Decodes a urlencoded string and performs necessary decoding depending on the used python version.

kartothek.core.urlencode.unquote_indices(index_strings: List[str]) → List[Tuple[str, str]]

Take a list of encoded column-value strings and decode them to tuples

input: quote(column)=quote(value) output (column, value)

Parameters

indices – A list of tuples where each list entry is (column, value)

Returns

List with column value pairs

Return type

List[str]
