What is Eureka?
Eureka broke a two-and-a-half-year silence with a release candidate, not a release.
Netflix's service registry had been quiet since early 2024, when three release candidates for 1.10.19 were cut in a single day with identical commit lists and never promoted. A fourth candidate in August 2026 finally moved: allocation-reduction work backported from the 2.x line, VIP address lookup metrics, servo replaced with spectator in the client, and xstream and jettison upgraded for known CVEs. The 2.x branch's last visible activity, 2.0.2, was two dependency-level changes.
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.
Eureka vs Tigris: editorial side-by-side
Eureka
2.5DEVOPS
Eureka broke a two-and-a-half-year silence with a release candidate, not a release.
◆ Current state
Netflix's service registry had been quiet since early 2024, when three release candidates for 1.10.19 were cut in a single day with identical commit lists and never promoted. A fourth candidate in August 2026 finally moved: allocation-reduction work backported from the 2.x line, VIP address lookup metrics, servo replaced with spectator in the client, and xstream and jettison upgraded for known CVEs. The 2.x branch's last visible activity, 2.0.2, was two dependency-level changes.
◆ Where it's heading
The shape of this release is maintenance by a project that still has production weight but no active feature agenda. The work that landed is dependency hygiene, allocation reduction and observability — what you ship to keep an existing fleet running, not what you ship to win new adoption. That 1.10.19 has sat in candidate state for over two years while the 2.x line stalled tells its own story.
◆ Prediction
The entries do not support a confident call on whether 1.10.19 is promoted to a final release; the pattern so far is candidates that expire rather than ship.
Tigris
5.0DEVOPS
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.
