Add the Power of Big Data Indexing to Your Data Lake

Varada’s dynamic and adaptive big data indexing solution enables to
balance performance and cost with zero data-ops.

Get Started!

Varada’s unique big data indexing technology serves as a smart acceleration layer on your data lake, which remains the single source of truth, and runs in the customer cloud environment (VPC). Varada enables data teams to democratize data by operationalizing the entire data lake while ensuring interactive performance, without the need to move data, model or manually optimize.

Our secret sauce is our ability to automatically and dynamically index relevant data, at the structure and granularity of the source. Varada enables any query to meet continuously evolving performance and concurrency requirements for users and analytics API calls, while keeping costs predictable and under control.

Zero Data-Ops.


Varada automatically accelerates queries according to workload behavior and automatic detection of hot data and bottlenecks. The platform also enables data teams to define business priorities and accordingly adjust performance and budgets, eliminating the need to build separate silos for each use case.
The platform seamlessly chooses which queries to accelerate and which data to index. Varada elastically adjusts the cluster to meet demand and optimize cost and performance.

Adaptive & Dynamic Indexing.

& Dynamic Indexing.

Our indexing technology breaks data, across any column, into nano-blocks. Varada automatically chooses the most effective index for each nano-block based on the data content and structure. We use a variety of indexes such as Bitmap, Dictionary, Trees, text analysis etc. and tailor each one to every nano block. This unique indexing technology is what makes all your data available and interactive.

Query Orchestrator

Manages queries and cluster resources according to budgets and workload priorities, and which elastically grows and shrinks the cluster resources based on the load.


Distributed Query Engine (Presto-based)

Includes a Coordinator node that optimizes and distributes queries, and Workers that execute queries using massively parallel processing.

Acceleration engine

Optimizes queries on the fly using adaptive indexing, data materialization, and intermediate result calculation based on workload insights.

Workload Monitoring & Learning Engine

Uses machine learning to detect repeating patterns and hotspots in queries and adaptively choose dynamic acceleration. This engine exposes information to data teams, provides full visibility, explores workloads, and prioritizes according to business needs.

Platform Overview

Varada’s big data infrastructure solution includes out-of-the-box native support for all community supported Presto SQL connectors to access a wide array of data sources. The Varada query engine also expands upon the open source Presto SQL query engine by adding enterprise grade support for high availability in the Coordinator and Workers, so both can withstand node failures. Varada’s cost-based optimizer extends the basic optimizer with knowledge of how and when to accelerate queries with a combination of adaptive indexes, cache, intermediate results. Varada workers are able to auto-scale based on dynamic workload and administrator configuration.Schedule A Demo

Observability and Insights

Varada continuously monitors cluster performance and resource utilization by analyzing each workload as an independent logical entity that serves specific business requirements.
Varada uses machine learning to detect repeating patterns and hotspots in workload and queries, which enable the platform to adaptively choose the optimal acceleration. The observability engine exposes deep actionable insights to data teams, so that they can effectively explore and monitor workloads, prioritize according to business needs while minimizing DataOps and time-to-insights.

The Power
of Adaptive Indexing

Varada’s unique indexing efficiently indexes data directly from the data lake across selected columns so that every query is optimized automatically. Varada indexes adapt to changes in data over time, taking advantage of Presto SQL’s vectorized columnar processing by splitting columns into small chunks, called nanoblocks™. Based on the data type, structure, and distribution of data in each nanoblock, Varada automatically creates an optimal index. To ensure fast performance for every query and each nanoblock, Varada automatically selects from a set of indexing algorithms and indexing parameters that adapt and evolve as data changes to ensure best fit index any data nanoblock.

At query time when running through the Varada endpoint, users see transparent performance benefits when filtering, joining and aggregating data. Varada transparently applies indexes to any SQL WHERE clause, on indexed columns, within a SQL statement. Indexes are used for point lookups, range queries and string matching of data in nanoblocks. Varada automatically detects and uses indexes to accelerate JOINs using the index of the key column. Varada indexes can be used for dimensional JOINs combining a fact table with a filtered dimension table, for self-joins of fact tables based on time or any other dimension as an ID, and for joins between indexed data and federated data sources. SQL aggregations and grouping is accelerated using nanoblock indexes as well, resulting in highly effective SQL analytics.

This example highlights the different techniques Varada leverages to optimize and accelerate SQL queries, including existing Presto queries:

Resource-Aware Intelligent Cost-Based Optimizer

Varada takes Presto's SQL distributed query engine and its built-in Cost-Based Optimizer (CBO) to the next level, by automatically analyzing and introducing indexes for filtering, joins and aggregates, continuously reanalyzing query performance on the fly.
Varada uses machine learning to decide when and what to optimize. With the benefit of lightweight indexing, Varada is able to use intelligent and elastic resource allocation, and leveraging intermediate results. The resulting cost model is exposed to administrators and users who can then prioritize specific user queries.

Varada’s platform, as well as workload observability and control center, are deployed in your VPC. Varada offers data teams flexible deployment models, to align with existing data infrastructure and requirements:
Presto-Integrated Deployment: customers with existing Presto clusters can leverage Varada’s connector-based deployment to seamlessly integrate Varada with active clusters and instantly accelerate workloads.
Standalone Deployment: a fully packaged and configured platform that is deployed on top of your data lake. Any SQL workload or BI tool can be connected to a Varada managed cluster via JDBC, ODBC, REST API or Varada’s query editor.
