Designing for Performance
Data Load Patterns
You can make your warehouse work better by picking the right data load patterns. Full loads move all the data at once. Incremental loads only move new or changed records. Using incremental loads puts less pressure on your system and saves time. This way, your warehouse stays updated and does not slow down other jobs.
When you are Designing for Performance, you need to think about how each pattern uses resources. Full loads use more capacity, especially with big tables. Incremental loads use less capacity and let you run more queries at once. In Microsoft Fabric, capacity depends on active per-query capacity unit seconds. The system spreads out work over 24 hours to keep things balanced.
You should also make your queries, data types, and schema design better. These steps help you use resources well and keep your warehouse running smoothly. Planning your data loads makes it easier to grow your solution and get fast analytics.
Tip: Try using incremental loads for daily updates. Use full loads only if you need to reload whole tables or fix problems.
Query Optimization
You can speed up your queries by using built-in features in Microsoft Fabric. These features help you get answers faster and use less capacity. Designing for Performance means using result set reuse, automatic statistics, and query plan caching.
Here is a table that shows how you can use these techniques:
You can use your SQL skills with cloud-native features by using the native execution engine in Microsoft Fabric. This engine runs queries right on lakehouse infrastructure. You get faster results, especially with Parquet and Delta formats. The engine uses columnar processing and vectorization, which helps with hard transformations and aggregations. You also do not have to move extra data, so your queries work better.
Use result set caching for queries you run often.
Let the system make and manage statistics.
Write queries that work well with columnar formats.
Check cache usage to see if your queries use caching.
Designing for Performance means using these features to get the best from your warehouse. You can run more queries at once and get answers faster. When you use smart data load patterns and query optimization together, you build a high-performance solution.
Data Ingestion
Full vs. Incremental Loads
Picking the right way to load data keeps your warehouse fast. You can use full loads or incremental loads. Each one works best in different situations.
With incremental loading, only new data goes into a Delta table. The old Parquet files and row groups stay the same. There are no deletes. Direct Lake can add new data without reloading VertiPaq column store elements.
Full loads move all your data every time you load. This is good if you need to reload everything after a big change. Full loads take more time and use more resources.
Incremental loads only move new or changed data. This saves time and money. Your warehouse stays up to date without moving all the data.
Incremental refresh lets you update big models fast and safely. You use less resources and keep your data safe. Incremental loading puts only new data into a Delta table. This keeps your data strong and updates quick.
Full Load: Loads all data, which takes more time and resources.
Incremental Load: Loads only new data, which is faster and cheaper.
Complexity: Full loads are simple, but incremental loads need careful updates.
When you plan data loads, think about how often your data changes. Also think about how much data you need to move. Use full loads for big changes. Use incremental loads for daily or frequent updates. This helps your warehouse work well and stay fast.
Staging Strategies
Staging data before loading helps you use resources better. It also makes your processes faster. You can use a staging area, like Fabric Lakehouse, to hold raw data first.
Efficient resource use: Staging helps you use resources wisely. You can process more data without slowing your main systems.
Faster queries: Staging makes your queries faster. You do not have to get data from the source every time.
Optimize queries: Pull raw data and stage it before changing it. This makes your processing better.
Parallel processing: Use tools like Azure Data Factory to split jobs. This makes data loads faster.
Incremental data loads: Only move new or changed data. This saves time and resources.
Caching and partitioning: Cache data you use a lot. Split big datasets into smaller parts. This helps your queries run faster.
These strategies help you load data faster and keep it safe. Staging helps you fix errors, change data formats, and handle big datasets. Your main warehouse does not slow down.

Using these transformation methods makes things easier and faster. Microsoft Fabric puts getting, changing, saving, and looking at data all together. This way helps you work quickly and makes ETL pipelines better.
Tip: Pick the right flow type for your data source. This keeps your ETL process easy and quick.
Error Handling
You need good error handling to keep your data correct and safe. Add steps in your pipeline to catch problems when getting, changing, or loading data. Use retry logic and alerts in Azure Data Factory to fix issues fast. Logging and checking help you watch data and see how things work.
Check your data before you load it.
Write down errors and watch your pipeline.
Set alerts for jobs that fail.
Use rollback steps to fix mistakes quickly.
Good error handling, like checking data and watching, helps you find problems early. Rollbacks and alerts help you fix issues fast. This keeps your data good and your ETL process strong.
Post-Load Tuning
After you load data, you can make your warehouse work better. Split your data by time or place to make queries faster. Use caching to save results for quick use. Materialized views help you answer the same queries without extra work. Change concurrency settings to let more people run queries at once.
Splitting data makes queries faster and easier.
Caching and materialized views save time on repeated queries.
Good concurrency management shares resources for many users.
Designing for Performance means tuning your warehouse after each load. These steps help you get answers faster and save money.
Resource Management
Capacity Planning
You need to plan your warehouse size. This helps keep it fast and saves money. First, look at what jobs you run. ETL jobs, real-time analytics, and BI reporting all need different things. Make separate places for development, testing, and production. This keeps your main warehouse safe and quick.
Think about these important points: Each job uses resources in its own way. If more people use the warehouse at once, you need more power. As your data gets bigger, you need more resources too.
Microsoft Fabric gives you different ways to set up capacity. You can pick flexible pricing or serverless models. These let you change resources when you need to. Choose the right SKU for your needs and budget. This helps you pay only for what you use. You can make your warehouse bigger or smaller as your business changes.
Tip: Set limits and alerts for usage. This helps you find problems before your warehouse slows down.
Monitoring
You need to watch your warehouse to keep it working well. Use built-in tools to check how it is doing. The Microsoft Fabric Capacity Metrics App shows you how much compute and capacity you use.
Set alerts for high usage. For example, get an email if CPU stays above 80% for five minutes. Use the Monitoring Hub to check things in real time. These steps help you fix problems before users notice.
Scaling
You can change your resources when your jobs change. Auto-scaling adds or removes power as needed. You do not have to do this by hand. Bursting gives extra power for short, busy times.
Auto-scaling matches resources to your jobs.
Bursting gives more power for heavy tasks.
Dynamic scaling saves money when things are quiet.
These ideas help keep your warehouse fast and save money. High-priority jobs always get enough power. You do not pay for resources you do not use.
Use Cases
Migration Scenarios
When you move data to Microsoft Fabric Warehouses, you have choices. Each choice works for different needs and goals. Here is a table that shows common ways to migrate:
You can pick "lift and shift" to move fast with few changes. This keeps your setup but may not be the fastest. If you want better results, you can check, plan, and rebuild your solution. This takes more time but gives you stronger stability and quicker data loads. You can also use tools like Azure Data Factory or Snowflake to help your data load work better.
Tip: Look at your current data flows before you start. This helps you pick the best way to move your data.
