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.
YugabyteDB’s automatic sharding overcomes PostgreSQL’s partition key limitations by allowing date range queries without modifying table partitioning. Thanks to its global secondary indexes, which don’t require a shared sharding key, YugabyteDB enhances performance by distributing rows across multiple servers. Discover the full advantages and see step-by-step instructions in our latest blog post.
Managing large PostgreSQL tables requires partitioning, which can complicate queries. Migrating to YugabyteDB simplifies scaling by automatically sharding and distributing data and minimizing partition reliance. The article includes demos on PostgreSQL’s partitioning limitations and YugabyteDB’s advantages in distributed tables and scalability.
Discover how to scale PostgreSQL for rapid app growth with our infographic that outlines the evolution to a resilient, compliant, globally scalable distributed deployment. Learn about distributed PostgreSQL’s forms, including multi-master asynchronous replication and sharded or shared-nothing setups, along with their advantages and challenges.
YugabyteDB 2.19.2 introduces full support for Read Committed Isolation with Wait-On-Conflict, essential for PostgreSQL users looking to seamlessly lift-and-shift applications to a distributed environment. This feature ensures parity with PostgreSQL while leveraging the scale and resilience of YugabyteDB, simplifying the transition for users.
Introducing PgCompute—a client-side extension for PostgreSQL aimed at revitalizing the use of database functions by allowing developers to create and optimize them seamlessly within their preferred IDE and programming language.
PostgreSQL offers robust features but has certain limitations in scalability, replication, resilience (and more). YugabyteDB addresses these issues through distributed design, storage efficiency, and transaction handling, providing a comprehensive solution when high availability, ACID, and scale are mandatory.
Distributed SQL offers greater scalability, availability, and geo-distribution of data compared to PostgreSQL, but it is important to understand the differences in behaviors between the two systems in order to make the most of your distributed SQL database.
YugabyteDB uses LSM Tree / SST Files to minimize the risk of data corruption, in contrast to PostgreSQL’s method. This approach, coupled with independent compactions and checksum verification, enhances data integrity.
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.
