Implement Performance Improvements in Queries and Report Visuals (DP-600 Exam Prep)

 
This post is a part of the DP-600: Implementing Analytics Solutions Using Microsoft Fabric Exam Prep Hub; and this topic falls under these sections: 
Implement and manage semantic models (25-30%) 
    --> Optimize enterprise-scale semantic models 
        --> Implement performance improvements in queries and report visuals

Performance optimization is a critical skill for the Fabric Analytics Engineer. In enterprise-scale semantic models, poor query design, inefficient DAX, or overly complex visuals can significantly degrade report responsiveness and user experience. This exam section focuses on identifying performance bottlenecks and applying best practices to improve query execution, model efficiency, and report rendering.

1. Understand Where Performance Issues Occur

Performance problems typically fall into three layers:

a. Data & Storage Layer

  • Storage mode (Import, DirectQuery, Direct Lake, Composite)
  • Data source latency
  • Table size and cardinality
  • Partitioning and refresh strategies

b. Semantic Model & Query Layer

  • DAX calculation complexity
  • Relationships and filter propagation
  • Aggregation design
  • Use of calculation groups and measures

c. Report & Visual Layer

  • Number and type of visuals
  • Cross-filtering behavior
  • Visual-level queries
  • Use of slicers and filters

DP-600 questions often test your ability to identify the correct layer where optimization is needed.

2. Optimize Queries and Semantic Model Performance

a. Choose the Appropriate Storage Mode

  • Use Import for small-to-medium datasets requiring fast interactivity
  • Use Direct Lake for large OneLake Delta tables with high concurrency
  • Use Composite models to balance performance and real-time access
  • Avoid unnecessary DirectQuery when Import or Direct Lake is feasible

b. Reduce Data Volume

  • Remove unused columns and tables
  • Reduce column cardinality (e.g., avoid high-cardinality text columns)
  • Prefer surrogate keys over natural keys
  • Disable Auto Date/Time when not needed

c. Optimize Relationships

  • Use single-direction relationships by default
  • Avoid unnecessary bidirectional filters
  • Ensure relationships follow a star schema
  • Avoid many-to-many relationships unless required

d. Use Aggregations

  • Create aggregation tables to pre-summarize large fact tables
  • Enable query hits against aggregation tables before scanning detailed data
  • Especially valuable in composite models

3. Improve DAX Query Performance

a. Write Efficient DAX

  • Prefer measures over calculated columns
  • Use variables (VAR) to avoid repeated calculations
  • Minimize row context where possible
  • Avoid excessive iterators (SUMX, FILTER) over large tables

b. Use Filter Context Efficiently

  • Prefer CALCULATE with simple filters
  • Avoid complex nested FILTER expressions
  • Use KEEPFILTERS and REMOVEFILTERS intentionally

c. Avoid Expensive Patterns

  • Avoid EARLIER in favor of variables
  • Avoid dynamic table generation inside visuals
  • Minimize use of ALL when ALLSELECTED or scoped filters suffice

4. Optimize Report Visual Performance

a. Reduce Visual Complexity

  • Limit the number of visuals per page
  • Avoid visuals that generate multiple queries (e.g., complex custom visuals)
  • Use summary visuals instead of detailed tables where possible

b. Control Interactions

  • Disable unnecessary visual interactions
  • Avoid excessive cross-highlighting
  • Use report-level filters instead of visual-level filters when possible

c. Optimize Slicers

  • Avoid slicers on high-cardinality columns
  • Use dropdown slicers instead of list slicers
  • Limit the number of slicers on a page

d. Prefer Measures Over Visual Calculations

  • Avoid implicit measures created by dragging numeric columns
  • Define explicit measures in the semantic model
  • Reuse measures across visuals to improve cache efficiency

5. Use Performance Analysis Tools

a. Performance Analyzer

  • Identify slow visuals
  • Measure DAX query duration
  • Distinguish between query time and visual rendering time

b. Query Diagnostics (Power BI Desktop)

  • Analyze backend query behavior
  • Identify expensive DirectQuery or Direct Lake operations

c. DAX Studio (Advanced)

  • Analyze query plans
  • Measure storage engine vs formula engine time
  • Identify inefficient DAX patterns

(You won’t be tested on tool UI details, but knowing when and why to use them is exam-relevant.)

6. Common DP-600 Exam Scenarios

You may be asked to:

  • Identify why a report is slow and choose the best optimization
  • Identify the bottleneck layer (model, query, or visual)
  • Select the most appropriate storage mode for performance
  • Choose the least disruptive, most effective optimization
  • Improve a slow DAX measure
  • Reduce visual rendering time without changing the data source
  • Optimize performance for enterprise-scale models
  • Apply enterprise-scale best practices, not just quick fixes

Key Exam Takeaways

  • Always optimize the model first, visuals second
  • Star schema + clean relationships = better performance
  • Efficient DAX matters more than clever DAX
  • Fewer visuals and interactions = faster reports
  • Aggregations and Direct Lake are key enterprise-scale tools

Design and Build Composite Models (DP-600 Exam Prep)

 
This post is a part of the DP-600: Implementing Analytics Solutions Using Microsoft Fabric Exam Prep Hub; and this topic falls under these sections: 
Implement and manage semantic models (25-30%) 
    --> Design and build semantic models 
        --> Design and Build Composite Models

What Is a Composite Model?

A composite model in Power BI and Microsoft Fabric combines data from multiple data sources and multiple storage modes in a single semantic model. Rather than importing all data into the model’s in-memory cache, composite models let you mix different query/storage patterns such as:

  • Import
  • DirectQuery
  • Direct Lake
  • Live connections

Composite models enable flexible design and optimized performance across diverse scenarios.

Why Composite Models Matter

Semantic models often need to support:

  • Large datasets that cannot be imported fully
  • Real-time or near-real-time requirements
  • Federation across disparate sources
  • Mix of highly dynamic and relatively static data

Composite models let you combine the benefits of in-memory performance with direct source access.

Core Concepts

Storage Modes in Composite Models

Storage ModeDescriptionTypical Use
ImportData is cached in the semantic model memoryFast performance for static or moderately sized data
DirectQueryQueries are pushed to the source at runtimeReal-time or large relational sources
Direct LakeQueries Delta tables in OneLakeLarge OneLake data with faster interactive access
Live ConnectionDelegates all query processing to an external modelShared enterprise semantic models

A composite model may include tables using different modes — for example, imported dimension tables and DirectQuery/Direct Lake fact tables.

Key Features of Composite Models

1. Table-Level Storage Modes

Every table in a composite model may use a different storage mode:

  • Dimensions may be imported
  • Fact tables may use DirectQuery or Direct Lake
  • Bridge or helper tables may be imported

This flexibility enables performance and freshness trade-offs.

2. Relationships Across Storage Modes

Relationships can span tables even if they use different storage modes, enabling:

  • Filtering between imported and DirectQuery tables
  • Cross-mode joins (handled intelligently by the engine)

Underlying engines push queries to the appropriate source (SQL, OneLake, Semantic layer), depending on where the data resides.

3. Aggregations and Hierarchies

You can define:

  • Aggregated tables (pre-summarized import tables)
  • Detail tables (DirectQuery or Direct Lake)

Power BI automatically uses aggregations when a visual’s query can be satisfied with summary data, enhancing performance.

4. Calculation Groups and Measures

Composite models work with complex semantic logic:

  • Calculation groups (standardized transformations)
  • DAX measures that span imported and DirectQuery tables

These models require careful modeling to ensure that context transitions behave predictably.

When to Use Composite Models

Composite models are ideal when:

A. Data Is Too Large to Import

  • Large fact tables (> hundreds of millions of rows)
  • Delta/OneLake data too big for full in-memory import
  • Use Direct Lake for these, while importing dimensions

B. Real-Time Data Is Required

  • Operational reporting
  • Systems with high update frequency
  • Use DirectQuery to relational sources

C. Multiple Data Sources Must Be Combined

  • Relational databases
  • OneLake & Delta
  • Cloud services (e.g., Synapse, SQL DB, Spark)
  • On-prem gateways

Composite models let you combine these seamlessly.

D. Different Performance vs Freshness Needs

  • Import for static master data
  • DirectQuery or Direct Lake for dynamic fact data

Composite vs Pure Models

AspectImport OnlyComposite
PerformanceVery fastDepends on source/query pattern
FreshnessScheduled refreshReal-time/near-real-time possible
Source diversityLimitedMultiple heterogeneous sources
Model complexitySimplerHigher

Query Execution and Optimization

Query Folding

  • DirectQuery and Power Query transformations rely on query folding to push logic back to the source
  • Query folding is essential for performance in composite models

Storage Mode Selection

Good modeling practices for composite models include:

  • Import small dimension tables
  • Direct Lake for large storage in OneLake
  • DirectQuery for real-time relational sources
  • Use aggregations to optimize performance

Modeling Considerations

1. Relationship Direction

  • Prefer single-direction relationships
  • Use bidirectional filtering only when required (careful with ambiguity)

2. Data Type Consistency

  • Ensure fields used in joins have matching data types
  • In composite models, mismatches can cause query fallbacks

3. Cardinality

  • High cardinality DirectQuery columns can slow queries
  • Use star schema patterns

4. Security

  • Row-level security crosses modes but must be carefully tested
  • Security logic must consider where filters are applied

Common Exam Scenarios

Exam questions may ask you to:

  • Choose between Import, DirectQuery, Direct Lake and composite
  • Assess performance vs freshness requirements
  • Determine query folding feasibility
  • Identify correct relationship patterns across modes

Example prompt:

“Your model combines a large OneLake dataset and a small dimension table. Users need current data daily but also fast filtering. Which storage and modeling approach is best?”

Correct exam choices often point to composite models using Direct Lake + imported dimensions.

Best Practices

  • Define a clear star schema even in composite models
  • Import dimension tables where reasonable
  • Use aggregations to improve performance for heavy visuals
  • Limit direct many-to-many relationships
  • Use calculation groups to apply analytics consistently
  • Test query performance across storage modes

Exam-Ready Summary/Tips

Composite models enable flexible and scalable semantic models by mixing storage modes:

  • Import – best performance for static or moderate data
  • DirectQuery – real-time access to source systems
  • Direct Lake – scalable querying of OneLake Delta data
  • Live Connection – federated or shared datasets

Design composite models to balance performance, freshness, and data volume, using strong schema design and query optimization.

For DP-600, always evaluate:

  • Data volume
  • Freshness requirements
  • Performance expectations
  • Source location (OneLake vs relational)

Composite models are frequently the correct answer when these requirements conflict.
