Karsient CodeShift

Transform Legacy Code. Accelerate Modernization.

CodeShift transforms legacy code and data workloads into modern, production-ready implementations — converting SQL, stored procedures, and ETL jobs into Databricks-native code while preserving business logic and transformation intent.

Why it exists

Problems CodeShift solves

Manual code conversion is slow and inconsistent across a large team

Legacy stored procedures and ETL jobs don't map 1:1 to modern equivalents

Limited documentation increases the risk of losing business logic in translation

Inconsistent legacy coding patterns make automated conversion harder to trust

No structured workflow for human review of AI-generated conversions

How it works

Inside the CodeShift process

Transform → Convert → Generate → Migrate → Validate

01

Transform

Take the object model and priorities produced by ShiftIQ as the transformation scope.

02

Convert

Apply AI-assisted, dialect-specific rules to convert each object.

03

Generate

Generate modern Databricks SQL, PySpark, or Delta Live Tables code.

04

Migrate

Move converted workloads into the target environment in planned, testable phases.

05

Validate

Route lower-confidence conversions to engineer review before sign-off.

Under the hood

How CodeShift converts legacy workloads

CodeShift combines a deterministic, dialect-specific rules engine with AI-assisted pattern generation — so common constructs convert instantly, and only genuinely ambiguous logic goes to a model.

1

Applies dialect-specific transformation rules for direct, high-confidence conversions

2

Uses AI to generate idiomatic PySpark/SQL for logic that doesn't map 1:1

3

Cross-checks every conversion against the business rules ShiftIQ identified upstream

4

Assigns a confidence score per object and routes anything below threshold to review

Capabilities

What's inside

01

AI-assisted code conversion

AI-driven translation of legacy code into modern, idiomatic Databricks implementations.

02

Legacy SQL modernization

Converts legacy SQL dialects and functions into Databricks SQL.

03

ETL transformation

Re-platforms ETL logic into Databricks-native pipelines and workflows.

04

Talend-to-Databricks conversion

Converts Talend jobs into PySpark and Delta Live Tables pipelines.

05

Informatica-to-Databricks conversion

Converts Informatica mappings and workflows into Databricks-native equivalents.

06

Vertica-to-Databricks conversion

Converts Vertica SQL and projection logic into Delta Lake-optimized implementations.

07

Stored-procedure modernization

Converts stored procedures into PySpark functions or SQL-based equivalents.

08

SQL-to-PySpark transformation

Transforms SQL-centric logic into distributed PySpark where it improves performance.

09

Source-to-target mapping

Produces a traceable map from every source object to its converted target implementation.

10

Business-rule preservation

Validates that business logic identified upstream is preserved through conversion.

11

Modern coding pattern generation

Generates code that follows current Databricks engineering best practice, not literal translation.

12

Automated migration documentation

Documents every conversion automatically, keeping the migration audit-ready.

13

Human review & approval workflows

Routes lower-confidence conversions to an engineer before anything ships to production.

FAQ

Common questions

No — CodeShift maximizes safe automation while explicitly flagging anything it isn't confident about, rather than silently producing incorrect code.
