Compare PostgreSQL vs. RocksDB vs. YDB

PostgreSQL stands out as a highly capable, open-source object-relational database system that has been actively developed for more than three decades, earning a solid reputation for its reliability, extensive features, and impressive performance. Comprehensive resources for installation and usage are readily available in the official documentation, which serves as an invaluable guide for both new and experienced users. Additionally, the open-source community fosters numerous forums and platforms where individuals can learn about PostgreSQL, understand its functionalities, and explore job opportunities related to it. Engaging with this community can enhance your knowledge and connection to the PostgreSQL ecosystem. Recently, the PostgreSQL Global Development Group announced updates for all supported versions, including 15.1, 14.6, 13.9, 12.13, 11.18, and 10.23, which address 25 reported bugs from the past few months. Notably, this marks the final release for PostgreSQL 10, meaning that it will no longer receive any security patches or bug fixes going forward. Therefore, if you are currently utilizing PostgreSQL 10 in your production environment, it is highly recommended that you plan to upgrade to a more recent version to ensure continued support and security. Upgrading will not only help maintain the integrity of your data but also allow you to take advantage of the latest features and improvements introduced in newer releases.

RocksDB is a high-performance database engine that employs a log-structured design and is entirely implemented in C++. It treats keys and values as byte streams of arbitrary sizes, allowing for flexibility in data representation. Specifically designed for rapid, low-latency storage solutions such as flash memory and high-speed disks, RocksDB capitalizes on the impressive read and write speeds provided by these technologies. The database supports a range of fundamental operations, from basic tasks like opening and closing a database to more complex functions such as merging and applying compaction filters. Its versatility makes RocksDB suitable for various workloads, including database storage engines like MyRocks as well as application data caching and embedded systems. This adaptability ensures that developers can rely on RocksDB for a wide spectrum of data management needs in different environments.

Trust YDB to manage your application state, no matter the size or frequency of modifications it undergoes. It excels at processing petabytes of data and millions of transactions each second without breaking a sweat. You can create analytical reports from the data housed in YDB, achieving performance levels akin to specialized database management systems. There is no need to sacrifice consistency or availability in the process. Leverage the YDB topics feature for dependable data transmission between your applications, or to access change data capture from standard tables. You have the option to select between exactly-once and at-least-once delivery semantics. YDB is engineered to operate across three availability zones, guaranteeing service continuity even if one zone experiences downtime. It automatically recovers from disk, server, or data center failures with minimal latency interruptions, ensuring your applications remain operational and resilient. With YDB, you can focus on scaling your applications while it takes care of the underlying infrastructure.
