Data v/s Index paths

[Manoj Mathai]

Slide #11 of http://www.slideshare.net/Couchbase/sizing-couchbase-server-cbc2014-clean suggests using different data paths for data and indexes. What does that mean exactly ?

I see the following under the default data folder ( /opt/couchbase/var/lib/couchbase/data )

• 1 folder per bucket
• 1 folder called @indexes
• some other files.

The bucket data and index data appears to be in separate paths already. Should they be on separate disks instead ?

Also, As per http://docs.couchbase.com/admin/admin/Misc/admin-datafiles.html , 
"The default disk path is typically used for development purposes only. If the server node is used for production, configure a different disk path." . If the couchbase server node has just 1 disk and is mounted on "/", does it make sense to change the "default" paths ?

Hi,

yes, it's better to have them on separate disks instead.
If you have only one disk, than not really.
