Greetings,
What is the expected amount of block storage capacity per robinhood
database entry when taking changelog activity from a recent version of
Lustre (≥2.7)? The robinhood version would be 2.5.6 or recent.
I have seen estimates of 1K/entry, is that still current? Does that
size represent records once written to block storage (file system) or
just in memory?
Hi Jeff,
1K per entry is an up-to-date estimation on the DB size on disk.
The DB engine caches information in memory according to the DB tunings
(in particular "innodb_buffer_pool_size").
Of course, the more entries fit into memory, the more performant is the
database.
Regards,
Trying to size a new robinhood server for a LFS with 2 billion files
and it's best to do it right the first time. ;-)
Thanks!
