Hi:
We are working with someone who is implementing a TDS for a large
aggregated dataset, in this case output from ROMS models. The
specific questions asked were:
Will recheckEvery also check existing files to see if they have
changed (had records added)? I only ask because, as I mentioned, we
are considering adding the hourly files to the current month's
file. Therefore, the current month's file will change (have a new
record) every hour.
Also, when the aggregation finds a new file (or modified one if it
checks that) will the dataset need to be retouched to speed load
times?
but the underlying question is also how best to set up the
aggregation, is it still true that things are speeded up if on
startup you "touch" each "file" so that the coordinate info is read
into cache, and exactly what does get checked and how on recheckEvery.
Thanks for any help,
-Roy
