+0 Vote Up -0Vote Down

September 3, 2014 By Severalnines

Running your database cluster on AWS is a great way to adapt to changing workloads by adding/removing instances, or by scaling up/down each instance. At Severalnines, we talk much more about scale-out than scale up, but there are cases where you might want to scale up an instance instead of scaling out. 

In this post, we’ll show you how to change instance sizes with respect to RAM, CPU and IOPS, and how to tune your Galera nodes accordingly. Moreover, this post assumes that …

Bug marketing - fixing MongoDB replication bugs in TokuMX
+0 Vote Up -0Vote Down

Asynchronous replication is lossy by nature. It is also useful in production especially for replication across a WAN where the latency for one or two network roundtrips between replicas is too much. Latency is reduced when replicas are nearby but that greatly increases cost from using more replicas. In MySQL land we have work-in-progress that uses enhanced semi-sync replication and binlog archivers to make the binlog 2-safe within a datacenter and greatly reduce the chance that a committed transaction is lost (some people call this lossless). Even better, it can be done …

Problem solved? Here is a short guide.
Preferred versionI prefer these questions over the ones that follow. I don't know whether the non-preferred variants …
