@Matthew No, db activity was very low at this time, and keys returned by this queries was deleted long time ago ( some of them at Dec 2015 )
I got this issue when proceed maintenance task which touch all keys in DB, list all keys by /keys?keys=true query, read, upgrade, save. We have some logic depends on 2i indexes results - ( count number of related keys ). But if it returns phantom keys, I cannot trust this data, need to double check by getting each object, but this is more expensive operation On Tue, Mar 8, 2016 at 10:21 PM, Matthew Von-Maszewski <matth...@basho.com> wrote: > Is the database being actively modified during your queries? > > Queries can lock down a "snapshot" within leveldb.
