For performance reasons, and for ease of setup, you may still wish to terminate HTTPS connections at your load balancer / reverse proxy, then use unencrypted HTTP between it and your CouchDB cluster. There’s still plenty of work to be done on the core database. This allows low latency access to data regardless of location. Basic authentication is a quick and simple way to authenticate with CouchDB.The main drawback is the need to send user credentials with each request which may be insecure and could hurt operation performance (since CouchDB must … CouchDB Core.

CouchDB parallel replications causes high cpu usage. You can draw many of these graphs that show how different features or attributes pull into different directions and thus shape the system they describe. CouchDB will start sending any changes that occur in the source to the target database. (When set it seems to be causing some tcp window size performance issues that lead to the huge delay for larger PUTs.) This is part 1 in a series of posts that describe our investigation into CouchDB as a solution to several database related performance issues facing the TextMe application..

After only a few short years, several of our database tables had over a million rows, a handful had over 10 million, and a few had over 30 million. Closed; Options. Closed; FAB-6442 systest FAB-2725 performance of couchdb. If you have followed this guide so far, using ionice will have no effect since you have set IO Scheduler to deadline or noop which doesn't use priorities. Need to performance test and stress test. 4. Look for cfq for a scheduler that works with priorities. 5.2.1.2. CouchDB: CouchDB supports both master-master and master-slave replication. Need to switch to using bulk operations to get optimal performance from CouchDB. FAB-6421 Fabric performance improvements - 1.x.
