InfluxDB has released a new engine that significantly increases performance and allows for unbounded cardinality, SQL support, and real-time analytics, making it ideal for use cases such as events, tracing, and ephemeral data. The new engine also supports native SQL queries, enabling users to connect using Postgres-compatible clients like psql and Grafana's Postgres data source. Additionally, InfluxDB has expanded the Data Explorer UI, made custom data retention easier, and added an onboarding wizard for the Arduino platform, while fixing various bugs to improve the user experience.
