Why Data Science & Advanced Predictive Analytics choose this tool

🎯
Built for
Data Science & Advanced Predictive Analytics
In-Depth Overview
Infino addresses the fundamental infrastructure bottleneck of managing separate clusters for vector search, keyword search, and analytical queries by storing data directly as standard Parquet files in object storage. By eliminating the need for expensive disk replicas and redundant systems, you can achieve up to a tenfold cost reduction compared to traditional search stacks like Elasticsearch or Qdrant. For data scientists and engineers building retrieval-augmented generation (RAG) applications or operational agents, Infino provides native integration with Model Context Protocol (MCP) and agent-to-agent (A2A) frameworks, enabling automated context ingestion from raw logs, documents, and snapshots. The open-source core engine is available under an Apache-2.0 license, giving you the flexibility to run single-node instances locally or via Python, Rust, and Node packages. However, transitioning from traditional Lucene-based setups requires accepting specific trade-offs, such as the initial lack of custom analyzers, fuzzy search syntax, and certain update write paths. If you manage large-scale logs, enterprise documents, or heavy vector workloads that incur unsustainable cloud bills on traditional storage architectures, Infino provides a streamlined architectural alternative centered on object storage and open file formats.

Key Use Cases

📊
Run SQL and vector search on the same data

54% faster search
✓ Pros
Significantly lower storage and operational costs than traditional search clusters
Open-source core available under Apache-2.0 license
Enables direct querying over standard Parquet files in object storage
Faster top-k keyword search and low-latency vector search performance
Zero application changes required when migrating from Elasticsearch via snapshot
· Cons
Does not support custom analyzers; text is indexed using the standard analyzer only
Lacks support for certain query types including fuzzy search, function_score, and geo
Missing specific write paths such as update scripts, sliced scroll, and reindex by query
Sorted searches remain faster on traditional Lucene setups
⚡ Editorial Verdict

Infino delivers significant cost reductions and high performance for vector and full-text search by leveraging Parquet files in object storage. However, you must evaluate its current limitations, such as the lack of custom text analyzers and certain advanced query types like fuzzy search, before migrating production workloads.

Questions & Answers

Frequently asked questions

What license is the open-source core under?

+
The open-source core engine is licensed under Apache-2.0.

Do I need Infino Cloud to use the engine?
