In this post, we discuss the significant performance gains achieved in rendering time series plots in Rerun, a multimodal time series database. Previously, plotting larger time series was slow, but with the release of version 0.13, the speed has improved drastically. The flexibility of Rerun’s data model comes at the cost of added overhead, particularly for small data like scalars. The post explains the main sources of overhead in producing and rendering time series plots and discusses the challenges of caching and cache invalidation. The post concludes by mentioning that there are still more performance improvements to be made in the future.
