Nathan Caza commented on COUCHDB-1946:
--------------------------------------

So, I've been experiencing this, I've had a script replicating 1-by-1 (no bulk 
api). I haven't had any issues, EXCEPT as replication goes on, small documents 
wiz by and now towards the end, all that is left is a large number of bigger 
documents.

I skipped large documents the first pass, but I presume had I not, I would have 
ran out of sockets/workers as they slowly filled up with the large 
transfers/documents.

Also to note that one of these, as an example, is about ~40MB (a unicode 
document/package I believe) , when simply gzipped becomes ~1.3MB.

Are there plans to support gzip compression?

> I have been able to replicate the Node.js NPM database until 40G or so, then 
> I get this:
> https://gist.github.com/stelcheck/7723362
> I one case I have gotten a flat-out OOM error, but I didn't take a dump of 
> the log output at the time.
> CentOS6.4 with CouchDB 1.5 (also tried 1.3.1, but to no avail). Also tried to 
> restart replication from scratch - twice - bot cases stalling at 40GB.
