- class tsdat.io.writers.CSVWriter[source]
Bases:
tsdat.io.base.FileWriter
Converts a xr.Dataset object to a pandas DataFrame and saves the result to a csv file using pd.DataFrame.to_csv(). Properties under the to_csv_kwargs parameter are passed to pd.DataFrame.to_csv() as keyword arguments.
- parameters: CSVWriter.Parameters[source]
Class Methods
Writes the dataset to the provided filepath.
Method Descriptions
- write(dataset: xarray.Dataset, filepath: pathlib.Path | None = None, **kwargs: Any) None [source]
Writes the dataset to the provided filepath.
This method is typically called by the tsdat storage API, which will be responsible for providing the filepath, including the file extension.
- Parameters:
dataset (xr.Dataset) – The dataset to save.
filepath (Optional[Path]) – The path to the file to save.
- class tsdat.io.writers.NetCDFWriter[source]
Bases:
tsdat.io.base.FileWriter
Thin wrapper around xarray’s Dataset.to_netcdf() function for saving a dataset to a netCDF file. Properties under the to_netcdf_kwargs parameter will be passed to Dataset.to_netcdf() as keyword arguments.
File compression is used by default to save disk space. To disable compression set the compression_level parameter to 0.
- class Parameters[source]
Bases:
pydantic.BaseModel
- compression_level: int = 1[source]
The level of compression to use (0-9). Set to 0 to not use compression.
- to_netcdf_kwargs: Dict[str, Any][source]
Keyword arguments passed directly to xr.Dataset.to_netcdf().
- parameters: NetCDFWriter.Parameters[source]
Class Methods
Writes the dataset to the provided filepath.
Method Descriptions
- write(dataset: xarray.Dataset, filepath: pathlib.Path | None = None, **kwargs: Any) None [source]
Writes the dataset to the provided filepath.
This method is typically called by the tsdat storage API, which will be responsible for providing the filepath, including the file extension.
- Parameters:
dataset (xr.Dataset) – The dataset to save.
filepath (Optional[Path]) – The path to the file to save.
- class tsdat.io.writers.ParquetWriter[source]
Bases:
tsdat.io.base.FileWriter
Writes the dataset to a parquet file.
Converts a xr.Dataset object to a pandas DataFrame and saves the result to a parquet file using pd.DataFrame.to_parquet(). Properties under the to_parquet_kwargs parameter are passed to pd.DataFrame.to_parquet() as keyword arguments.
- parameters: ParquetWriter.Parameters[source]
Class Methods
Writes the dataset to the provided filepath.
Method Descriptions
- write(dataset: xarray.Dataset, filepath: pathlib.Path | None = None, **kwargs: Any) None [source]
Writes the dataset to the provided filepath.
This method is typically called by the tsdat storage API, which will be responsible for providing the filepath, including the file extension.
- Parameters:
dataset (xr.Dataset) – The dataset to save.
filepath (Optional[Path]) – The path to the file to save.
- class tsdat.io.writers.SplitNetCDFWriter[source]
Bases:
NetCDFWriter
Wrapper around xarray’s Dataset.to_netcdf() function for saving a dataset to a netCDF file based on a particular time interval, and is an extension of the NetCDFWriter. Files are split (sliced) via a time interval specified in two parts, time_interval a literal value, and a time_unit character (year: “Y”, month: “M”, day: “D”, hour: “h”, minute: “m”, second: “s”).
Properties under the to_netcdf_kwargs parameter will be passed to Dataset.to_netcdf() as keyword arguments. File compression is used by default to save disk space. To disable compression set the compression_level parameter to 0.
- class Parameters[source]
Bases:
NetCDFWriter
- parameters: SplitNetCDFWriter.Parameters[source]
Class Methods
Writes the dataset to the provided filepath.
Method Descriptions
- write(dataset: xarray.Dataset, filepath: pathlib.Path | None = None, **kwargs: Any) None [source]
Writes the dataset to the provided filepath.
This method is typically called by the tsdat storage API, which will be responsible for providing the filepath, including the file extension.
- Parameters:
dataset (xr.Dataset) – The dataset to save.
filepath (Optional[Path]) – The path to the file to save.
- class tsdat.io.writers.ZarrWriter[source]
Bases:
tsdat.io.base.FileWriter
Writes the dataset to a basic zarr archive.
Advanced features such as specifying the chunk size or writing the zarr archive in AWS S3 will be implemented later.
- parameters: ZarrWriter.Parameters[source]
Class Methods
Writes the dataset to the provided filepath.
Method Descriptions
- write(dataset: xarray.Dataset, filepath: pathlib.Path | None = None, **kwargs: Any) None [source]
Writes the dataset to the provided filepath.
This method is typically called by the tsdat storage API, which will be responsible for providing the filepath, including the file extension.
- Parameters:
dataset (xr.Dataset) – The dataset to save.
filepath (Optional[Path]) – The path to the file to save.
