⚡ GPU-Accelerated Vector Indexing: 12x Speed via NVIDIA cuVS
The headline story of Elastic 9.3.0 is the integration of NVIDIA cuVS — NVIDIA's open-source library for GPU-accelerated vector search and data clustering — directly into Elasticsearch. This is the most significant vector performance breakthrough in Elastic's history:
Improvement in vector indexing throughput (GPU vs CPU)
Faster force merge operations with GPU acceleration
Lower search latency across the platform
Higher ingest throughput vs. previous version
What Is NVIDIA cuVS?
NVIDIA cuVS (CUDA Vector Search) is an open-source, GPU-accelerated library specifically designed for high-performance approximate nearest neighbor (ANN) search, clustering, and vector operations at scale. By integrating cuVS into Elasticsearch's vector indexing pipeline, Elastic has offloaded the computationally intensive work of building and searching HNSW vector indexes from CPU to GPU — dramatically accelerating the process.
How GPU Vector Indexing Works in Elastic 9.3.0
Data Arrives
Documents with dense vector fields are ingested into Elasticsearch via the standard bulk API
GPU Offload
NVIDIA cuVS intercepts vector indexing operations and offloads HNSW graph construction to available NVIDIA GPUs
Parallel Build
GPU builds vector index segments in parallel — 12x faster than CPU-only construction
CPU Freed
CPU cycles freed from vector indexing can be redirected to improve search query throughput
Accelerated Merge
Force merge operations — previously a bottleneck — run 7x faster using GPU-accelerated clustering
Who Benefits From GPU Acceleration?
🧠 AI/ML Teams
Building RAG pipelines or semantic search on large embedding datasets can now index data 12x faster — dramatically reducing time from data ingestion to search-ready state.
🔒 Security Teams
Security data pipelines that ingest millions of events per second gain faster indexing headroom — keeping detection latency low even during traffic spikes.
📊 Observability Teams
Logs and traces that use semantic search features benefit from faster vector index builds during high-volume log ingestion windows.
🏢 Enterprise Data Teams
Organizations ingesting billions of vectors for recommendation or personalization systems can now operate with fewer nodes while maintaining throughput.
⚙️ Technical Note: Availability
GPU-accelerated vector indexing is available as a Technical Preview in Elastic 9.3.0 for self-managed deployments with compatible NVIDIA GPUs. Elastic Cloud managed deployments have access via EIS Cloud Connect (see below). GPU requirements: NVIDIA CUDA-compatible GPU with CUDA 11.8+. Supported GPUs include NVIDIA A100, H100, A10G, and RTX 4090/4080.
🤖 Elastic Agent Builder GA: Chat With Your Data, Build Custom AI Agents
Elastic 9.3.0 marks the general availability of Elastic Agent Builder — the platform's native toolset for building AI agents that can reason over Elasticsearch data and take real-world actions:
Natural Language Data Chat
Users can now ask questions of their Elasticsearch data in plain English — no query language required. Agent Builder interprets natural language, generates ES|QL or query DSL, and returns conversational answers grounded in your actual data.
Custom AI Agent Development
Developers can build domain-specific AI agents using Elasticsearch data as the knowledge backbone — combining retrieval, reasoning, and action in a single integrated development experience.
Workflow Integration (9.3 New)
In 9.3.0, Agent Builder integrates directly with Elastic Workflows — giving agents the ability to not just answer questions but take reliable, automated actions based on what they find.
Context Engineering Platform
Agent Builder is Elastic's implementation of the "context engineering" paradigm — connecting AI models to your operational data to reduce hallucination and improve answer quality in production AI applications.
Multi-Modal Retrieval
Agents can retrieve across lexical (BM25), semantic (dense vector), and sparse vector (ELSER) indexes simultaneously — returning the most relevant context from any data type.
Governed Access Control
Agent queries respect Elasticsearch's field-level and document-level security — AI agents only access data their owners are authorized to see.
💬 Example: Chatting With Security Data
"Show me all authentication failures in the last 24 hours for privileged accounts, grouped by source IP, and flag any IPs that have failed more than 10 times."
🔍 Translating natural language to ES|QL query...
📊 Querying authentication logs index (last 24h)...
🔐 Filtering for privileged account types (admin, root, service)...
📈 Aggregating by source_ip with failure count threshold > 10...
🚨 Flagging 3 suspicious IPs: 192.168.1.45 (47 failures), 10.0.0.22 (23 failures), 172.16.0.8 (11 failures)...
Found 3 flagged IPs with brute-force indicators. Top risk: 192.168.1.45 with 47 failures against admin accounts. Recommend triggering automated isolation workflow? [Run Elastic Workflow]
🔄 Elastic Workflows: Native Automation Arrives in the Elasticsearch Platform
Elastic Workflows, launching as a Technical Preview in 9.3.0, is one of the most architecturally significant additions to the Elastic Stack in years — bringing orchestration logic directly to where your data lives:
What Are Elastic Workflows?
Elastic Workflows integrates native workflow automation into the Elasticsearch Platform itself. Instead of shipping data to external orchestration systems, teams can now define, execute, and monitor automated workflows — both rule-based and AI-driven — directly within their Elastic deployment, using the same security context, permissions, and data access that power search, observability, and security operations.
Two Workflow Modes
📋 Rules-Based Automation
Define deterministic workflows triggered by conditions in your data — alert thresholds, index patterns, scheduled intervals. Reliable, auditable, and predictable.
Use Case: "When error rate > 5% for 10 minutes, trigger incident ticket creation and page on-call engineer."
🤖 Agentic Automation
AI agents reason over your data and decide what actions to take. Agent Builder provides the intelligence; Elastic Workflows provides the action execution engine.
Use Case: "When anomaly detected, have Agent Builder analyze context, determine root cause, draft remediation steps, and notify the relevant team automatically."
Elastic Workflows Use Cases by Solution
| Solution | Trigger | Automated Action |
|---|---|---|
| Security (SOC) | Attack Discovery detects threat | Agent analyzes, generates Entity AI Summary, auto-creates case, escalates to analyst |
| Observability (SRE) | Log anomaly detected via Streams | Agentic root cause analysis, Bedrock LLM consultation, automated alert + runbook generation |
| Search | Index lag exceeds threshold | Auto-trigger force merge, notify team, log event for audit trail |
| Data Management | ILM policy triggers on index age | Automated rollover, snapshot, and tiering to frozen or cold storage |
| Business Process | Customer data pattern change detected | Notify stakeholder, trigger downstream API, log compliance event |
💾 DiskBBQ: Cost-Efficient Vector Storage for Massive Scale
Elastic 9.3.0 introduces DiskBBQ (bbq_disk) — a new vector index type that makes large-scale vector deployments dramatically more cost-efficient:
How DiskBBQ Works
DiskBBQ is a cluster-based disk-native vector index format. Unlike the in-memory HNSW approach (bbq_hnsw), DiskBBQ stores quantized vector clusters on disk rather than in RAM — trading a modest latency overhead for massive reductions in memory and storage costs. It's designed specifically for large datasets where the full vector index exceeds available RAM.
DiskBBQ vs. Existing Vector Index Types
| Index Type | Storage Location | Memory Usage | Best For | Available Since |
|---|---|---|---|---|
| bbq_disk (DiskBBQ) | On-disk (clustered) | ✅ Minimal | Large datasets (100M+ vectors) | 9.3.0 |
| bbq_hnsw (BBQ) | Memory-mapped | ⚠️ Moderate | High-throughput, low-latency production | 9.0 (default since 9.1) |
| hnsw (Standard) | Memory-mapped | ❌ High | Maximum accuracy requirements | Legacy |
| flat (Brute Force) | Memory | ❌ Highest | Small datasets, exact search | Legacy |
How to Use DiskBBQ
// Create index with DiskBBQ vector type
PUT /my_vectors
{
"mappings": {
"properties": {
"embedding": {
"type": "dense_vector",
"dims": 1536,
"index": true,
"index_options": {
"type": "bbq_disk"
}
}
}
}
}
// Query is identical to other vector types
POST /my_vectors/_search
{
"query": {
"knn": {
"field": "embedding",
"query_vector": [...],
"k": 10
}
}
}When to Use DiskBBQ
✅ Use DiskBBQ When:
- Vector dataset exceeds available RAM
- Cost efficiency is more critical than single-digit millisecond latency
- Storing 100M+ vectors in production
- Running hybrid workloads where RAM is shared with other processes
- Archival or cold vector search use cases
⚠️ Stick to bbq_hnsw When:
- Sub-10ms vector search latency is required
- Dataset fits comfortably in RAM
- High-QPS real-time recommendation or search scenarios
- Maximum recall accuracy is non-negotiable

💽 Storage Efficiency: bfloat16 Vectors & Pattern Text Compression
Elastic 9.3.0 introduces two complementary storage innovations that dramatically reduce the cost of running AI-scale workloads:
🔢 bfloat16 Dense Vector Support
Elastic 9.3.0 adds native support for bfloat16 (Brain Floating Point 16-bit) format for dense vector storage. This 16-bit precision format, widely used in AI/ML hardware, reduces the memory and disk footprint of vector datasets by approximately 50% compared to 32-bit floats — while maintaining sufficient precision for most semantic search use cases.
| Format | Bits per Value | 1M Vectors (1536-dim) | Precision |
|---|---|---|---|
| float32 (Legacy) | 32-bit | ~6.1 GB | Full precision |
| bfloat16 (9.3 New) | 16-bit | ~3.1 GB (50% less) | High (ML-native) |
| BBQ (int1) | 1-bit (quantized) | ~0.19 GB (97% less) | Approximate |
📝 Pattern Text Compression for Logs
Elastic 9.3.0 introduces a new pattern_text field type that applies intelligent pattern-based compression to log messages. By identifying and compressing repetitive structures in log data, this feature delivers up to 50% storage savings for high-volume observability workloads — without sacrificing searchability or accuracy.
How Pattern Text Compression Works
Before: Stores each log message individually, even when 90% of the text is identical template text
After: Identifies the common pattern template, stores it once, and only indexes variable values — dramatically reducing storage per document
Example Pattern: "User {user_id} logged in from {ip} at {timestamp}" — only user_id, ip, and timestamp stored per document; template text compressed
☁️ EIS Cloud Connect GA: Inference Without GPU Management
The Elastic Inference Service (EIS) via Cloud Connect is now generally available for self-managed customers — solving one of the key operational challenges of running AI-powered search in private environments:
What Is EIS Cloud Connect?
Cloud Connect enables self-managed Elasticsearch clusters to offload inference operations — embedding generation, reranking, and agentic RAG — to managed GPU infrastructure in Elastic Cloud, while keeping all data, storage, and indexing local. This means organizations in regulated industries or private environments can use enterprise-grade AI models without provisioning their own GPUs or managing model operations.
🚫 No GPU Provisioning
Run semantic search and reranking models without owning or managing GPU infrastructure.
🔐 Data Stays Local
Your data, storage, and indexing remain within your own infrastructure. Only inference requests travel to Elastic Cloud.
