What is Dapr?

Dapr is shipping fixes across three release branches at once, most of them in workflows.

Dapr maintains 1.16, 1.17 and 1.18 concurrently, and the current window is entirely bug fixes backported across all three. The 1.18.3 release carries fifteen of them; the older branches receive the subset that applies. Workflow durability dominates — stalled workflows left unrecoverable after the last worker disconnected, terminate events silently dropped when batched, orphaned activity-result reminders retrying forever, and continue_as_new iterations sharing one unbounded trace.

What is Tigris?

Tigris keeps publishing its architecture, and the newest post opens up the storage engine itself.

This feed is Tigris's engineering blog, and it alternates between protocol critique and descriptions of how the product answers it. The most recent post opens the internals: how Tigris composes ACID metadata, global placement, caching, replication, and background work on FoundationDB into a multi-region object store. Before it came the Recycle Bin — deletion of objects and buckets on top of immutable storage in an active-active geo-replicated database — plus two posts dissecting SigV4 and presigned URLs, and one on agent-native onboarding through tigris init --agent.

Dapr vs Tigris: editorial side-by-side

D
Dapr
DEVOPS
5.0

Dapr is shipping fixes across three release branches at once, most of them in workflows.

◆ Current state

Dapr maintains 1.16, 1.17 and 1.18 concurrently, and the current window is entirely bug fixes backported across all three. The 1.18.3 release carries fifteen of them; the older branches receive the subset that applies. Workflow durability dominates — stalled workflows left unrecoverable after the last worker disconnected, terminate events silently dropped when batched, orphaned activity-result reminders retrying forever, and continue_as_new iterations sharing one unbounded trace.

◆ Where it's heading

The failure reports are notably specific about who was affected and under what configuration, and several describe components that looked healthy while silently doing nothing — input bindings that never activated because a warmup probe had a hardcoded three-second budget, an Azure credential chain that stopped at SPIFFE instead of falling back. That class of bug is what a maturing distributed runtime finds once the obvious crashes are gone. Release candidates are published openly before each patch, so the same fixes appear several times in the feed.

◆ Prediction

Expect continued patch releases across all three branches, with workflow recovery paths the likeliest source given how many of this window's fixes cluster there.

5.0

Tigris keeps publishing its architecture, and the newest post opens up the storage engine itself.

◆ Current state

This feed is Tigris's engineering blog, and it alternates between protocol critique and descriptions of how the product answers it. The most recent post opens the internals: how Tigris composes ACID metadata, global placement, caching, replication, and background work on FoundationDB into a multi-region object store. Before it came the Recycle Bin — deletion of objects and buckets on top of immutable storage in an active-active geo-replicated database — plus two posts dissecting SigV4 and presigned URLs, and one on agent-native onboarding through tigris init --agent.

◆ Where it's heading

The writing is doing product work. Each protocol post establishes a problem — SigV4's canonicalization and clock skew, presigned URLs as deliberate replay attacks, S3 egress pricing on ClickHouse restores — and positions Tigris behavior as the answer, which makes the blog a migration funnel rather than a changelog. The architecture post is a different move: publishing the FoundationDB composition is a credibility play aimed at buyers who need to believe a newer object store can hold multi-region data.

◆ Prediction

Expect the protocol-critique-then-Tigris-answer format to continue, with the egress-cost framing recurring as the clearest paid migration path. Feature announcements will likely stay embedded in essays rather than appearing as release notes.
