ELASTICSEARCH
REPLACEMENT.

You know the operational burden: 3,000+ config knobs, JVM tuning, shard calculators, master election storms, and a team of specialists to keep it running. XERJ is a drop-in replacement — same API on port 9200, same query DSL, same client libraries — at a fraction of the resource cost.

THE COST OF ELASTICSEARCH

Infrastructure cost: $500K–2M / 3 years. RAM is the bottleneck (50–70% of budget). A 4-node cluster needs 8.5 GB just to idle. Scale that to 10 indices and you're buying RAM for the JVM, not for your data.
Specialized engineers: $150K/year each. ES requires dedicated operators who understand shard allocation, heap sizing, GC tuning, ILM rollover, and cross-cluster replication. Most teams need 2–3.
GC pauses cause p95 spikes. JVM stop-the-world pauses inject 50–200 ms latency spikes that show up in your SLOs and your on-call pages.
Feature-gated pricing. SSO, RBAC, ML anomaly detection, and cross-cluster search are locked behind Platinum+ licensing. The enterprise bill is opaque and non-negotiable.
Ecosystem tax. Running ES means also running Kibana (Node.js, 3.5 s p75 load time), Logstash (JRuby, 500 MB–2 GB RAM), and Beats (OOM-killed after upgrades). Four services to operate before your first query.

THE XERJ ANSWER

Drop-in API compatibility. Port 9200, same endpoints: POST /:index/_search, POST /_bulk, POST /_aliases. Existing ES client libraries work unchanged.
21× less memory at idle. No JVM heap, no GC pauses. 400 MB RSS vs 8.5 GB for a comparable ES cluster. Predictable latency at every percentile.
2.8× less disk. Domain-aware columnar compression with 9 automatic encodings. Same data, smaller footprint.
One binary replaces five. No Kibana, no Logstash, no Beats, no separate vector DB. REST API + Prometheus metrics + native ingest — all in-process.
All features, one tier. Auth, TLS, RBAC, aggregations, vector search, hybrid queries — everything ships in the binary. No platinum paywall.
