PgBench is widely used for testing database performance, but its default ‘TPC-B like’ workload may not accurately represent true performance. To achieve more realistic load testing, users can employ custom SQL scripts within PgBench. In this demonstration, we’ll show how these adjustments work using YugabyteDB.
Discover how to identify CPU, RAM, or I/O pressure in your database by utilizing Linux metrics and the Pressure Stall Information (PSI) metric. This blog post also demonstrates how to query Linux information using PostgreSQL and the file_fdw extension, offering valuable insights for DBAs and developers.
Let’s walk through some examples to see the importance of the conditional WHERE clause in PostgreSQL, especially when dealing with data that requires extensive filtering.
Discover efficient methods to partition data in your queries. Explore techniques like GROUP BY, window functions, recursive CTE queries, and the DISTINCT ON clause to optimize performance and scalability
Understanding the PostgreSQL version you’re using is crucial for feature availability and informed decision-making, especially with cloud-managed services. Continue reading to learn how to check your PostgreSQL version.
Discover how the LIKE operator enables pattern matching with wildcards and indexing for specific access patterns, focusing on scenarios where the wildcard is at the beginning or end of the pattern. The examples and demonstrations are performed on YugabyteDB, a PostgreSQL-compatible database with variations in storage implementation.
When indexing JSON documents in PostgreSQL, you can add indexes for the access patterns just like with relational table columns. We will walk through an example of this using the Pokémon GO Pokédex as a dataset, utilizing YugabyteDB, a distributed SQL database compatible with PostgreSQL.
DBAs often need to generate SQL statements using SQL queries and then execute them. PostgreSQL has many features that can help. Let’s walk through an example using YugabyteDB, which is Postgres-compatible and provides the same SQL language and catalog views.
The Orafce extension for PostgreSQL can be used to quickly and easily generate random strings to fill in a text column. Let’s look at an example on how to use Orafce, on either your PostgreSQL database or on a PostgreSQL-compatible database, like YugabyteDB.
