Re: [thredds] Disabling the cache for file that are routinely overwritten

Hi Rich:

1) I wonder what happens if the TDS is in the middle of reading the file when it gets overwritten?

2) What is the use case for this overwriting?

TDS folks,

We have several providers that routinely overwrite files with new
data, for example, overwriting a file called "" with new
data each day.

As I understand it from reading
it appears that if we don't want to cache certain datasets, we have two choices:

1) Turn off caching for ALL datasets served by TDS, by modifying the
threddsConfig.xml to read:

2) Turn off caching for AN INDIVIDUAL dataset served by TDS, by
setting a<datasetRoot>  with the cache="false"/>  option, and then
specifying each individual dataset.

But if we have a bunch of datasets in a directory that we would like
to turn off caching for, is there a way to turn off caching in
I tried using<datasetRoot with cache="false">  in the specification of
a<datasetScan>  but that didn't seem to work.

I certainly could have missed something.   But if not, it would be
nice to have more ability to control the cache on a dataset-by-dataset
basis in the future.
