cfdm.Field.persist_metadata

Field.persist_metadata(inplace=False)

Persist the data of metadata constructs into memory.

Persisting turns an underlying lazy dask array into an equivalent chunked dask array, but now with the results fully computed and in memory. This can avoid the expense of re-reading the data from disk, or re-computing it, when the data is accessed on multiple occasions.

Performance

persist_metadata causes delayed operations to be computed.

New in version (cfdm): 1.12.0.0
