If my math is correct, tofINLSCorr is ~60MB per record: 30000 * 1024 * 2 =
61,440,000 (and only 2048 bytes per db row).
If I remember correctly, that table from 2009 was replaced with the
optimized version because it was too slow.
Now, eTOF has ~4MB per entry (equals to db row) = 1,000,000 * 4, which is a
single 4MB chunk and is going to be handled very differently at the DB
level... Let's see how it goes.

Pretty straightforward.
Considering that I get a single instance of the Calibrations_tof /
tofINLSCorr is approximately 1 GB, it seems likely to me that 4 MB
entries should not be an issue.

Sorry, you are correct: 60 MB for the tofINLSCorr table (1 GB was after this converted into a CINT text file, so lots of bytes unassociated with the actual payload). Thanks for the correction and additional comments, Dmitry.

Subj. A new Offline DB table was created for Yannick. Let's see if 4MB records are manageable...
