xarray.DataTree.persist#
- DataTree.persist(**kwargs)[source]#
Trigger computation, keeping data as chunked arrays.
This operation can be used to trigger computation on underlying dask arrays, similar to
.compute()
or.load()
. However this operation keeps the data as dask arrays. This is particularly useful when using the dask.distributed scheduler and you want to load a large amount of data into distributed memory. Like compute (but unlike load), the original dataset is left unaltered.- Parameters
**kwargs (
dict
) – Additional keyword arguments passed on todask.persist
.- Returns
object (
DataTree
) – New object with all dask-backed coordinates and data variables as persisted dask arrays.
