Thanks @deepkaran.salooja for your quick answer
Below mentioned are stats that i have from Index Stats API
Data size on index is showing 9.17G while on disk this API shows index is occupying 10.31G
However if i really login to machine and check folder size for index i have completely a new number which is 9.7G
Also i have a small stat for indexer itself which is something like this
We have allocated 10G to indexer and it used is showing up as 8.3G which doesn’t again correspond to any of the numbers above
Is there somewhere a technical architecture or documentation explaining internal of couchbase index and how it works?
