Bol.com is using an ELK stack for a logsearch platform that can easily process a daily volume of 300M logevents worth 185GB of data. Keeping the indexing fast is one thing, but keeping search fast at the same time is another.
Bol.com will be hosting a Meetup where Renzo Toma (Metrics Engineer @bol.com) will talk about tuning, lots of metrics, scaling, our failures and our successes.
