What is Dragonfly?

Dragonfly speeds up slot lookups on 2.0 as its cluster-mode fixes keep coming.

Dragonfly maintains two incremental lines, 1.40 and 2.0, with small targeted releases. The 2.0 line has fixed dropped writes during slot migration and moved experimental slot-based sharding to Fibonacci hashing. i2.0.6 on October 30 makes GetSlotInfo faster, another cluster-mode refinement.

What is rsyslog?

rsyslog keeps adding cloud outputs, with Kinesis in October after CloudWatch in August.

rsyslog publishes a scheduled-stable snapshot every two months. April added YAML configuration and native OpenTelemetry protobuf output, June an Elastic Beats input and TCP compression, and August an imkubernetes input that tails pod and container logs, segmented disk-assisted queues and a CloudWatch Logs output. The October 8.2610.0 snapshot adds an Amazon Kinesis Data Streams output and an experimental producer-local queue.

Dragonfly vs rsyslog: editorial side-by-side

D
Dragonfly
INFRA · APIS
5.0

Dragonfly speeds up slot lookups on 2.0 as its cluster-mode fixes keep coming.

◆ Current state

Dragonfly maintains two incremental lines, 1.40 and 2.0, with small targeted releases. The 2.0 line has fixed dropped writes during slot migration and moved experimental slot-based sharding to Fibonacci hashing. i2.0.6 on October 30 makes GetSlotInfo faster, another cluster-mode refinement.

◆ Where it's heading

The 2.0 line is maturing through cluster and migration work, while 1.40 gets targeted performance backports. Release cadence has slowed from paired weekly builds to occasional single fixes.

◆ Prediction

Expect further 2.0.x builds focused on cluster mode and slot migration; whether scope-based memory tracking gets switched on is still unclear.

R
rsyslog
INFRA · APIS
2.5

rsyslog keeps adding cloud outputs, with Kinesis in October after CloudWatch in August.

◆ Current state

rsyslog publishes a scheduled-stable snapshot every two months. April added YAML configuration and native OpenTelemetry protobuf output, June an Elastic Beats input and TCP compression, and August an imkubernetes input that tails pod and container logs, segmented disk-assisted queues and a CloudWatch Logs output. The October 8.2610.0 snapshot adds an Amazon Kinesis Data Streams output and an experimental producer-local queue.

◆ Where it's heading

Across 2026 rsyslog has moved from a host syslog daemon toward a container and cloud log shipper, adding inputs for Kubernetes and outputs for AWS services each cycle. Queueing is the other active area.

◆ Prediction

The next scheduled-stable snapshot is due in December on the two-month rhythm; which outputs it adds is unclear from the feed.
