tiled.client.dataframe.DaskDataFrameClient

class tiled.client.dataframe.DaskDataFrameClient(context: Context, *, item, structure_clients, structure=None, include_data_sources=False)[source]

Client-side wrapper around an dataframe-like that returns dask dataframes

__init__(context: Context, *, item, structure_clients, structure=None, include_data_sources=False)

Methods

`__init__`(context, *, item, structure_clients)
`append_partition`(dataframe, partition)
`asset_manifest`(data_sources)	Return a manifest of the relative paths of the contents in each asset.
`build_metadata_patches`([metadata, specs, ...])	Build valid JSON Patches (RFC6902) for metadata and metadata validation specs accepted by patch_metadata.
`compute`()	Alias to client.read().compute()
`data_sources`()
`delete_tree`()
`export`(filepath[, columns, format])	Download data in some format and write to a file.
`include_data_sources`()	Ensure that data source and asset information is fetched.
`login`()	Depending on the server's authentication method, this will prompt for username/password:
`logout`()	Log out.
`metadata_copy`()	Generate a mutable copy of metadata, specs, and access_tags for validating metadata (useful with update_metadata())
`new_variation`([structure])	This is intended primarily for internal use and use by subclasses.

`raw_export`([destination_directory, max_workers])	Download the raw assets backing this node.
`read`([columns])	Access the entire DataFrame.
`read_partition`(partition[, columns])	Access one partition in a partitioned (dask) dataframe.
`refresh`()
`replace_metadata`([metadata, specs, ...])	EXPERIMENTAL: Replace metadata entirely (see update_metadata).
`structure`()	Return a dataclass describing the structure of the data.
`update_metadata`([metadata, specs, ...])	EXPERIMENTAL: Update metadata via a dict.update- like interface.
`write`(dataframe)
`write_partition`(dataframe, partition)
