rex.rechunk_h5.chunk_size.TimeseriesChunkSize

class TimeseriesChunkSize(shape, dtype, chunk_size=2, weeks_per_chunk=None)[source]

Bases: rex.rechunk_h5.chunk_size.BaseChunkSize

Compute Timeseries chunks based on dtype, and weeks_per_chunk

Parameters
  • shape (tuple) – Array shape

  • dtype (str | np.dtype) – Array data type

  • chunk_size (int, optional) – Chunk size in MB, by default 2

  • weeks_per_chunk (int, optional) – Number of weeks per time chunk, if None scale weeks based on 8 weeks for hourly data, by default None

Methods
