This Week in Fluvio #16
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 v0.9.14
Connector logs
Logs from connectors are now accessible from the CLI
fluvio connector logs <connector name>
In this example output, we can see some error output from the connector that would have previously been inaccessible.
Example:
$ fluvio connector logs my-test-mqtt -f
2021-12-15T05:20:21.770042Z ERROR mqtt: Mqtt error MqttState(Deserialization(PayloadSizeLimitExceeded(16635)))
2021-12-15T05:20:27.684853Z ERROR mqtt: Mqtt error MqttState(Deserialization(PayloadSizeLimitExceeded(16635)))
CLI Consumer wait spinner
Using the CLI consumer now has a new spinner to give feedback about the stream waiting for data.
Here's a short clip of the spinner in action with streaming data.
Change to multi-word subcommands
Given that these are still long commands, we've added aliases too
| Previous subcommand | New subcommand | New alias |
|---|---|---|
| smartmodule | smart-module | sm |
| tableformat | table-format | tf |
| derivedstream | derived-stream | ds |
CLI shell autocompletions
This actually isn't new, but it was hidden. Thanks to bohlmannc for helping us resolve this!
$ fluvio completions -h
fluvio-completions 0.0.0
Generate command-line completions for Fluvio
Run the following two commands to enable fluvio command completions.
Open a new terminal for the changes to take effect.
$ fluvio completions bash > ~/fluvio_completions.sh
$ echo "source ~/fluvio_completions.sh" >> ~/.bashrc
USAGE:
fluvio completions <SUBCOMMAND>
FLAGS:
-h, --help Prints help information
SUBCOMMANDS:
bash Generate CLI completions for bash
fish Generate CLI completions for fish
help Prints this message or the help of the given subcommand(s)
