To create a filter in Databricks SQL Analytics, you must add a WHERE clause to your query. For example, if you wanted to see data only for a specific date range, you could write a question like this: "SELECT * FROM table WHERE date BETWEEN '2022-01-01' AND '2022-12-31'".

Filters allow you to quickly and easily find the information you need to make informed decisions.

4) Query Parameters

Query parameters in Databricks SQL Analytics provide a way to make your queries more flexible and reusable. Using parameters, you can create a question that can run with different values without modifying the underlying code.

You can create a query with different values without changing the underlying code. To create a parameter, specify a placeholder. For example, instead of hard-coding a date range in your query, you could create a parameter for the start date and another for the end date and then supply those values when you run the query.

Query parameters make running the same question multiple times with different inputs easy, saving you time and effort.

5) Query Snippets

Query snippets in Databricks SQL Analytics are pre-written code inserted into your queries to save time and effort. Query snippets can include commonly used SQL statements, functions, or complete questions.

To use a query snippet, navigate to the SQL Analytics interface and select the "Query Snippets" option. From there, you can browse the available snippets and choose the one you want to use. The selected snippet will then insert into your query, where you can modify it as needed.

Query snippets are a great way to save time and simplify the query writing process and are especially useful for users new to SQL or the Databricks platform.

1. Indexing:

Indexing is a database optimisation technique that speeds up the query processing time. In Databricks, indexes can be created on specific columns or tables to speed up the query execution time.

2. Partitioning:

Partitioning is another optimisation technique in which large datasets are divided into smaller, more manageable units. In Databricks, you can partition data by time, key, or both, to speed up query execution time.

3. Compression:

Compression is a technique for reducing the size of data stored in a database. Compression reduces the size of the data stored on disk, reducing the time required to read the data from disk. In Databricks, you can use various compression techniques such as Snappy, Zlib, and LZO to optimise performance.

4. Caching:

Caching is a technique that stores frequently used data in memory for faster access. In Databricks, you can cache tables to improve query performance, especially for frequently used queries.

5. Materialised Views:

Materialised views are precomputed tables that can be used to speed up the query execution time in Databricks SQL Analytics. Materialised views can be created in Databricks and refreshed on a schedule or demand.

Query optimisation is making changes to a query to improve its performance. In Databricks, you can optimise queries using indexes, partitioning, compression, and other techniques.

6. Data Skew:

Data skew occurs when a small number of rows in a large dataset dominate the query processing time. In Databricks, you can address data skew using bucketing, partitioning, and sampling techniques.

So, performance optimisation is critical to the success of any SQL analytics platform, and Databricks provides a range of tools and techniques to help optimise performance. Whether you're working with large datasets or complex queries, it's essential to keep performance optimisation in mind to ensure your SQL analytics run quickly and efficiently.
