Exploiting column chunks for faster ingestion and lower memory use

To enable working with more kinds of datasets in Rerun, the 0.18 release introduces a new column oriented API and performance improvements to help handle larger time-series.

To enable working with more kinds of datasets in Rerun, the 0.18 release introduces a new column oriented API and performance improvements to help handle larger time-series. To make it easier and more efficient to deal with pre-recorded data, we're introducing a new api, send_columns, for sending time-series columns to Rerun, as well as a cli tool for merging, pruning, and compacting.rrd files. If you can't wait to try out the new faster chunk ingestion in Rerun 0.18, you can load the 2.25M scalars dataset from the benchmark mentioned above directly in your browser here.
