Hey all,

I am hoping there is someone else in the same boat as I am.  We are running 
Puppet 4.2.2, along with PuppetDB 4.3.0.  I am seeing low duplication rate 
which I think is contributing to our queuing problems in PuppetDB.  The 
queue will fluctuate from 0-100 queued, to up to 2000.  We have around 4500 
nodes, and we are using 8 threads on our PuppetDB server.  I am seeing that 
the low duplication rate is caused by hashes not matching and a full insert 
running which is expensive on the DB instead of just updating the time 
stamp.  I don't know why these would not be matching, and may need help as 
far as how to find something like this.  I see items in PuppetDB3 for this, 
but not 4.  I see that using timestamp and other items which change each 
time will cause the catalog to never be the same, but I would think we 
would have 0% duplication if this was the case.  I am also seeing that 
things are improved in 4.4.0 as far as performance and a missing index is 
corrected that may speed things.  I am wondering what others have done/seen 
with this and whether upgrading to 4.4.0 would do me good.  I am thinking 
it would as many things appear to fixed around the issues I am seeing. 
 Thanks in advance,

Mike
