Eureka vs Manticore Search
A side-by-side editorial comparison of Eureka and Manticore Search — release velocity, themes, recent moves, and the top alternatives to consider.
Eureka vs Manticore Search: at a glance
What is Eureka?
Eureka cut its first release in two years, and the notes live in a release candidate, not the tag.
Netflix's Eureka reached v1.10.19 in August 2026 after a candidate train that started in January 2024. The final tag's body is a single CI fix — the JDK setup in the publish workflow — byte-identical to rc.6 before it. The actual accumulated changes sit in rc.4: replacing servo with spectator in the client, EIP support for secondary ENIs, allocation-reduction backports from the 2.x line, VIP address lookup metrics, and xstream upgrades clearing two CVEs.
What is Manticore Search?
Manticore 31.0.7 undoes a 2x COUNT(DISTINCT) slowdown its own collation fix caused.
Manticore Search's 31.x tags so far are fixes rather than features. 31.0.3 and 31.0.4 were CI and packaging work; 31.0.7 restores string COUNT(DISTINCT) speed after the 29.18.5 collation fix made it 2x slower (1.1 s to 2.4 s on the logs10m benchmark) by calling tolower() per byte. A lookup table replaces the call without changing hash values, so secondary indexes and histograms stay compatible.

Eureka cut its first release in two years, and the notes live in a release candidate, not the tag.
◆ Current state
Netflix's Eureka reached v1.10.19 in August 2026 after a candidate train that started in January 2024. The final tag's body is a single CI fix — the JDK setup in the publish workflow — byte-identical to rc.6 before it. The actual accumulated changes sit in rc.4: replacing servo with spectator in the client, EIP support for secondary ENIs, allocation-reduction backports from the 2.x line, VIP address lookup metrics, and xstream upgrades clearing two CVEs.
◆ Where it's heading
This is a maintenance-mode project shipping a catch-up release rather than a roadmap. The substantive content is backports and dependency hygiene — the perf work is explicitly ported from 2.x, and the last two candidates exist only to bump xstream and fix the publish pipeline. The 2.0.x line saw its own small patch, so both lines are alive but neither is being extended.
◆ Prediction
Direction is hard to read from a feed where the release tag carries less information than its candidates. The pattern suggests further releases will be driven by CVE remediation in transitive dependencies rather than by feature work.
Manticore Search
5.0DEVOPS
Manticore 31.0.7 undoes a 2x COUNT(DISTINCT) slowdown its own collation fix caused.
◆ Current state
Manticore Search's 31.x tags so far are fixes rather than features. 31.0.3 and 31.0.4 were CI and packaging work; 31.0.7 restores string COUNT(DISTINCT) speed after the 29.18.5 collation fix made it 2x slower (1.1 s to 2.4 s on the logs10m benchmark) by calling tolower() per byte. A lookup table replaces the call without changing hash values, so secondary indexes and histograms stay compatible.
◆ Where it's heading
October has been correctness work on string handling (range filters, collation-aware COUNT(DISTINCT)) followed by fixing the performance cost of those fixes. The 31.x line still appears in the feed without notes on what features justified the major version.
◆ Prediction
Expect more 31.0.x patches in this vein. What new capability defines 31.x remains unclear from these entries.
