Elasticsearch vs rush
A side-by-side editorial comparison of Elasticsearch and rush — release velocity, themes, recent moves, and the top alternatives to consider.
Elasticsearch vs rush: at a glance
What is Elasticsearch?
Agent Builder, Elastic's newest surface, is where most of this month's Kibana CVEs live.
The visible feed window is one coordinated disclosure batch: ten Kibana advisories published within a minute of each other on August 13, spanning the 8.19, 9.3, 9.4 and 9.5 branches. Four of the six most recent concern Agent Builder — private agents readable and tamperable by non-owners, an A2A JSON-RPC endpoint that derives a conversation id from user-supplied input, and a missing cross-feature privilege check. The remainder cover Fleet issuing over-scoped Elastic Agent API keys and an Elastic Defend endpoint-event disclosure via field-value suggestions.
What is rush?
Rush spent 2026 making distributed task ownership correct, starting with a breaking 1.0.
rush is the Redis-backed distributed computing backend behind mlr3's parallel tuning: workers pull tasks, push results and are tracked through heartbeats. Since 1.0.0 in March 2026 it has shipped five releases in four months, almost all correcting how tasks and workers are owned and identified under failure. The most recent lets each worker start in its own mirai call so it can spawn local daemons.

Agent Builder, Elastic's newest surface, is where most of this month's Kibana CVEs live.
◆ Current state
The visible feed window is one coordinated disclosure batch: ten Kibana advisories published within a minute of each other on August 13, spanning the 8.19, 9.3, 9.4 and 9.5 branches. Four of the six most recent concern Agent Builder — private agents readable and tamperable by non-owners, an A2A JSON-RPC endpoint that derives a conversation id from user-supplied input, and a missing cross-feature privilege check. The remainder cover Fleet issuing over-scoped Elastic Agent API keys and an Elastic Defend endpoint-event disclosure via field-value suggestions.
◆ Where it's heading
Authorization is the single recurring failure mode here — every one of these is a caller-identity or privilege-check mistake, not memory safety or injection. That is the predictable cost of extending a permissions model built for dashboards and saved searches to a layer that acts on a user's behalf. Fixes are shipping inside ordinary patch releases (9.4.5, 9.5.1) rather than as a dedicated hardening effort.
◆ Prediction
Expect further Agent Builder advisories as that surface widens, and pressure to consolidate its ownership and privilege checks into one enforcement path instead of patching endpoint by endpoint.
rush
2.5INFRA · APIS
Rush spent 2026 making distributed task ownership correct, starting with a breaking 1.0.
◆ Current state
rush is the Redis-backed distributed computing backend behind mlr3's parallel tuning: workers pull tasks, push results and are tracked through heartbeats. Since 1.0.0 in March 2026 it has shipped five releases in four months, almost all correcting how tasks and workers are owned and identified under failure. The most recent lets each worker start in its own mirai call so it can spawn local daemons.
◆ Where it's heading
The through-line is moving responsibility from the controller to the worker. 1.0.0 rewrote the task lifecycle and dropped the seed mechanism; 1.2.0 moved fail_tasks(), finish_tasks(), pop_task() and push_running_tasks() from Rush onto RushWorker so only the worker that ran a task can mark it done, and gave worker ids random suffixes so they cannot collide. 1.1.0 had already removed phantom failed tasks when a worker crashes between evaluations.
◆ Prediction
With ownership and identity settled, the remaining pressure points are heartbeat and lost-worker detection; expect the next releases to tighten failure recovery rather than add API surface.
