This Week in Fluvio #17

Dec 8, 2021

Welcome to This Week in Fluvio, our weekly newsletter for development updates to Fluvio open source. Fluvio is a distributed, programmable streaming platform written in Rust.

 

New Release - Fluvio v0.9.15

 

TableFormat improvements

Prior to this release, rendering events with fluvio consume --output=full-table required events to arrive as individual JSON objects. But now we can additionally accept a list of events as an array of JSON objects.

Example topic data. Mix of JSON objects, and an array of objects.

{"key1":"a","key2":"1","key3":"Alice","id":123}
{"key1":"b","key2":"2","key3":"Bob","id":456}
{"key1":"c","key2":"3","key3":"Carol","id":789}
[{"key1":"x","key2":"10","key3":"Alice","id":123},{"key1":"y","key2":"20","key3":"Bob","id":456},{"key1":"c","key2":"30","key3":"Carol","id":789}]

Check out the TableFormat docs for more information about using TableFormat.
