A few months ago, I wrote about my first experiments with TideSQL, the MariaDB storage engine powered by TidesDB.

10 days ago, an article by Naomi Cannon on Reddit caught my attention; it included a link to the full article on Medium. As I read through the article, I didn’t notice any major errors or false statements. What surprised me a bit was the detailed, technical knowledge in this article, which is unusual for a typical tech blogger. What bothered me about this article was that she mainly bashed MariaDB without offering any meaningful or useful conclusions or advice on what to do (e.g., using InnoDB instead of always jumping on the latest bandwagon, or using a different database…Read more

This is the compute primitive you need to rank or filter embeddings by similarity directly in SQL. ANN indexing (e.g. HNSW, IVF) is the next milestone for fast large-scale similarity search; and this function provides … Continued The post DISTANCE() and VECTOR_DISTANCE(): Vector Similarity in Percona Server for MySQL 9.7 appeared first on Percona.Read more

  Evaluating LLM Models for DBA Tasks Large language models are increasingly capable of performing practical systems-administration tasks. I wanted to understand how well they could handle something more specialized: database administration. To explore this, I developed a harness for evaluating the ability of different LLMs to execute real DBA tasks on remote systems. My … Continued The post Evaluating LLM models for DBA tasks appeared first on Percona.Read more

A while ago, we discussed the cross-site replication feature of the Percona PXC operator. Recently, a similar cross-site replication feature was introduced in the Percona (PS MySQL) operator v1.2.0, a topology based on Group Replication/InnoDB Cluster.

The same non-standard behavior can be observed in MariaDB, MySQL, and […]Read more

Magento normally uses InnoDB for orders, order items, invoices, and other transactional data. However, analytical reports have another workload.
