I mean, what happens if I transfer the file whil orcallator.se is writing to it, and it is incomplete ? Will orca gracefully detect that some filds are missing from a recodd and ignore the record and process it the next time ?

Yes, if the file is updated at the next transfer, then orca will reread it and pick up the
new record.  The other thing that orcallator.se tries to do is an atomic write,
so the two record will be written at once.  This is needed if there are two
orcallator.se writing to the same output file.

No, the RRDs will not be obsolete.  You may not see the remaining data for that
day in Orca since orca can't deal with orcallator-YYYY-MM-DD files that
change the number of columns of data they have.
