Speed up COG usage #44

Open wildintellect opened 3 years ago

wildintellect commented 3 years ago

There are some tricks to getting faster reading of COG formatted files, many of these but not necessarily all could apply to ADE and DPS scripts reading COG files. https://github.com/developmentseed/titiler/blob/856b37924276b35c4ac33762dcef478fa75d6168/deployment/aws/cdk/config.py#L20-L28

The easiest one is (in Jupyter notebook syntax)

%env GDAL_DISABLE_READDIR_ON_OPEN=EMPTY_DIR

Need to figure out which ones are relevant, and how best to apply them. Might need to be per notebook/dps job since there may be times that users want/need to read side-car files.
