`RedisWorkQueue.stats` read XPENDING, which counts entries delivered to a consumer and not yet acknowledged — work in progress. Entries sitting in the stream undelivered were counted nowhere, so an engine hours behind reported itself idle: on the house, `pending: 4` while the group's lag was 1554. The group's own `lag` is the missing number. `backlog` now carries it on both queues (`len(_items)` in memory), leads the health tile, and a sustained one publishes `engine_degraded` from the timer thread — named with the flow most of the waiting work belongs to, sampled from the undelivered tail, since that is the actionable half. It is a summary problem rather than a /utils/health 503: a backlog should not restart the container. Also drops the keyspace `scan_iter` `stats()` did per poll to count parked items — it walked every state and idempotency key twice per ten seconds — for a set the park/unpark path maintains.

Fluksio
Fluksio is a node-based automation software that brings trust and reliability to your flow. It just works and looks good. Get started by running
pip install fluksio
fluksio serve
and you're ready to go.
For data science
You can turn your existing data science project into a flow by decorating your functions with @node ...
# myresearch/train.py
import fluksio
from fluksio import Port, node
@node(
requires=["dataset", Port("lr", "float")],
provides=[Port("loss", "float", stream=True), Port("weights", "artifact")],
device="gpu", device_policy="prefer",
)
def fit(dataset, lr, epochs=25):
for epoch in range(epochs):
loss = step(...)
yield {"loss": loss} # published as it happens, kept as a series
return {"weights": fluksio.save_artifact("weights.pt")}
... and passing them to a Flow:
# myresearch/pipeline.py
from fluksio import Flow, Port
from myresearch.data import prepare
from myresearch.evaluate import evaluate
from myresearch.train import fit
train = Flow("train", nodes=[prepare, fit, evaluate],
inputs=[Port("lr", "float", initial=0.01)], outputs=["score"])
Fluksio will automatically infer the order of nodes based on the inputs and outputs you defined. When everything is set, you can launch your first run as follows:
fluksio run train --lr 0.05 --wait
Checkout our documentation for more infos.
Some other features
- Flows: typed messages between nodes, wired by name, edited on a canvas or declared in code. Every change is a commit in a git repository you own.
- Runs: an experiment and a CI-style job are the same entity. Parameters, seed, result, per-node timings, artifacts and the commit it ran at.
- Dashboards: charts and controls bound to the same messages the flows carry, with no separate metrics pipeline.
- Remote workers:
pip install fluksio-workeron the GPU box; it dials out over one websocket, so nothing there has to be reachable.
Fluksio can also be used for facility automation. Visit us on fluksio.com or go straight to our documentation.
