Percona Live Dublin recap` I was a speaker at Percona Live in Dublin on September 26, 2017, where I presented about the InfluxDB Internals. The event featured over 140 speakers covering topics such as MySQL, MongoDB, Elasticsearch, and use cases for large databases from various companies. I expected to hear more opinions about using traditional engines for time series data, but instead, attendees were curious about the advantages of an engine designed specifically for this type of data. My talk focused on compression algorithms, retention policy, and sharding, which received positive feedback. The conference provided opportunities to speak with database administrators working with traditional databases, gathering valuable stories and scenarios that can help improve InfluxDB's performance and maintainability.
