Full-text indexes are stored in folders (named after the .nsf file), that always reside in the same subfolder as the .nsf file itself. I propose to add an option to the server document, to place all full-text indexes into a dedicated location, similar to specifying the log path for transaction logging.
Many administrators are concerned about the number of full-text indexed databases (and the granularity of indexing) they want to allow: they are concerned about the storage space eaten up and the amount of disk I/O.
On the other hand, for some databases, full-text indexes are strictly recommended (Condensed Directory Catalog), absolutely required (searchable web applications) or at least very, very handy. Additionally, users get more and more used to the "google way" of managing their data: searching instead of filing.
While it might not be necessary for IBM to target search capabilities on par with (or in excess of) Google, a dedicated storage location for full-text indexes would address the issues mentioned above:
  • It would be a lot easier to add more storage space just for indexes
  • Disk I/O could be spread over more physical disks or even controllers
I'm not sure how much performance would be to gain by this move, but maybe it would even be possible to increase the indexing frequency.

good idea to place the FTI on inexpensive disks

Very good idea ! And it should be so easy to accomplish :-)

This would be a huge I/O improvement. I've had to turn off ft indexing during the day on our all large databases. It just kills web apps when it updates and daily is not soon enough.

Yes, yes, yes, and another Y E S. I do have customers that turn it on on their mail server, and the difference for the users is important. However, it does require a well managed server and one that is not already sucking wind. That is also why I think that along with this, maybe separating out the task that does NOTHING BUT FTIs would be beneficial

Now available in 8.5.3!

Finally. And it only took about 4 years ...
Anyhow, I won't complain about my wish coming true. :-)
