Modern data teams want flexibility and performance without breaking what already works. Many organizations rely on Databricks to power their analytical workloads. However, when it’s time to modernize infrastructure, reduce cost, or adopt an open, multi-cloud platform, migration often feels complex. Code rewrites, catalog rebuilds, and permission mismatches can turn what should be an upgrade into a long and risky project.  

Yeedu changes that experience. It enables you to move existing Databricks workloads to Yeedu using a no code data migration flow intentionally built to simplify Databricks notebooks and jobs migration, while directly connecting to your Databricks Unity Catalog setup, preserving your Spark logic, and accelerating workloads using its high-performance Turbo Engine. This approach drastically reduces the friction typically associated with migrating Databricks notebooks and jobs into new environments.

If you use Photon, you’ll feel at home with Turbo

Many Databricks users depend on the Photon Engine for faster Spark SQL and DataFrame execution. Yeedu delivers the same vectorized acceleration with its Turbo Engine, designed for both compatibility and performance.

In practice, teams running CPU-bound analytics see 4–10× faster runtimes on Yeedu compared to unoptimized Spark engines. The Turbo Engine works transparently with your existing code, ensuring the same performance acceleration you expect from Photon and often better efficiency on modern hardware. This makes Yeedu a compelling option for Spark workload performance optimization without any code changes.

Key takeaways

  • No need to disable or rewrite Photon-optimized notebooks  
  • The Turbo Engine automatically accelerates your Spark SQL, DataFrame workloads  
  • Faster execution, lower compute costs, and more predictable runtimes  
  • Turbo Engine is included with Yeedu compute at no additional cost

Databricks notebooks and jobs migration without rebuilding your code

Yeedu eliminates the need for disruptive rewrites. Your Spark transformations, joins, window functions, and Structured Streaming logic continue to run exactly as before making Databricks notebooks and jobs migration smooth, predictable, and fully compatible with your existing logic. The platform is designed for code and operational continuity. You retain all your existing data flows and gain consistent execution across clouds, all enabled by Yeedu’s built-in capabilities as a Databricks migration tool.

Yeedu also supports advanced Databricks functionality:

  • dbutils support: File system operations, widgets, secrets, and notebook utilities etc are natively supported or mapped to Yeedu equivalents
  • Built-in functions: Common Databricks SQL functions such as is_account_group_member(), current_user() are fully handled by Yeedu to preserve behavior and logic  
  • Auto Loader compatibility: Streaming pipelines built with Databricks Auto Loader continue to work seamlessly on Yeedu. The platform natively supports incremental file discovery for continuous ingestion.

Unity Catalog connection, not duplication

One of the most time-consuming aspects of migration is rebuilding catalogs and permissions. With Yeedu, that step disappears. Yeedu directly connects to your existing Databricks Unity Catalog setup.  

Your tables, views, and schemas stay where they are, and your access controls continue as defined. Yeedu respects your existing governance setup rather than copying or replacing it.  

Benefits  

  • No duplicate catalogs to manage  
  • No regranting of permissions  
  • Unified lineage and metadata remain governed by Unity Catalog

Orchestrate your workflows with Airflow

Yeedu doesn’t just support Airflow. It migrates your Databricks Workflows into Airflow DAGs for you. During migration, Yeedu analyzes each workflow and automatically generates an equivalent DAG that preserves what matters to you dependencies, retries, SLAs, schedules, and conditional logic.  

This created a ready-to-run Airflow representation managed by Yeedu, bringing modern Airflow workflow orchestration to your Spark and notebook pipelines.

Once migrated, you operate everything “the Airflow way.” The Yeedu Airflow Operator submits and monitors Spark jobs or notebooks directly from your DAGs. Because your orchestration is now expressed as code, it is version controlled, testable, and repeatable across environments.  

In short, you keep the intent of your Databricks Workflows but gain the reliability and transparency of Airflow, with all the heavy lifting handled by Yeedu.

A three-phase approach to safe migration

Phase 1 - Legacy HMS unlock and UC modernization  

Break the dependency on the legacy Hive Metastore by converting its metadata tables, grants, and ownership into native Unity Catalog objects. This makes your governance portable outside Databricks and prepares the environment for Databricks notebook migration or larger multi-workload transitions.

Phase 2 - Complete environment inventory  

Scan the entire workspace to produce a detailed Unity Catalog inventory of tables, views, functions, volumes, and dependency graphs. The resulting report becomes the blueprint for migrating Databricks jobs, enabling quick lookups, lineage analysis, and permission validation.

Using this unified inventory and analysis, teams can validate lineage, permissions, and dependencies confidently ensuring safer Databricks notebooks and jobs migration across large, multi-team environments.

Note: Phases 1 and 2 are one-time setup processes that modernize the legacy environment and generate reliable migration blueprints.

Phase 3 - Workflow migration and operational readiness  

Use the blueprint to analyze existing jobs and notebooks, update them for the new UC structure, and generate orchestration assets such as Airflow DAGs. Validate safely with dry runs, then promote to production with confidence.

If new pipelines or workflows are added later, simply re-run this phase to migrate the additional assets to Yeedu.

What stays the same (so risk stays low)

  • Your existing Spark and SQL logic executed faster by the Turbo Engine  
  • Delta Lake features such as time travel and schema evolution remain supported  
  • RBAC and external storage access policies remain intact under Unity Catalog governance

The business impact of moving to Yeedu

  • No extra manual effort, migration in finger tips  
  • 4–10× faster workloads: The Turbo Engine delivers consistent acceleration  
  • Up to 60% lower compute cost: Optimized CPU utilization and predictable runtime behavior  
  • Multi-cloud ready: Deploy across AWS, Azure, and GCP without changing code

Validate in days, not months

You don’t need a massive migration project to see results.  

Start with a single pipeline that currently suffers from slow performance or SLA breaches. Connect it to Yeedu, run it using the Turbo Engine, and measure runtime stability, error rates, and cost improvements. Once validated, expand the same playbook across other workloads.

Who should consider Yeedu

Yeedu is a cloud cost optimization solution built for data teams that want Databricks-level governance and performance with greater flexibility, cost control, and openness. It’s ideal for organizations seeking to modernize their Spark infrastructure using a no code data migration path, without giving up years of investment in code, catalog, and governance.
