I’ve been talking a lot about message systems in distributed architectures lately. And one of the slides I show in my talks is a slide about compressing messages before writes to the database. In other words, if you have 150k messages per second coming in which would translate 1:1 in writes and force your database(s) to incur a 150k write per second load, you pull in all those messages in to memory for a short period (say one minute) and group them and write the group in batch. Depending on how much you can group, you can easily cut your write load by an order of magnitude. (more…)
After being a fairly heavy user of NSQ over the past year or so and finding that it was missing a few features, I decided to jump in and try to add them myself. The only issue was that I didn’t know Go. Since something as simple as not knowing the language the application was written in has never stopped me before, I wasn’t going to let it stop me now.
