The Cassandra Query Language (CQL) is the primary language for communicating with the Apache Cassandradatabase. The most basic way to interact with Apache Cassandra is using the CQL shell, cqlsh. Using cqlsh, you can create keyspaces and tables, insert and query tables, plus much more.

Queue waits in MySQL (and relational databases in general) refer to the time processes or threads spend waiting for access to shared resources. These can have a significant impact on database performance, often manifesting as slower query execution times, reduced throughput, and contention issues. #MySQLPerformance @MinervaDB #dba https://zurl.co/tlEc
Context switches, where the CPU shifts between threads, can impact #InnoDB performance in #MySQL.Voluntary switches happen when a thread waits for resources, while involuntary switches occur when a thread's CPU time expires, both adding overhead to database operations. #MySQLPerformance @MinervaDB #dba https://zurl.co/zEph

PostgreSQL 17 officially launched and with several new features: Improved Performance: Optimizations that speed up processing and improve efficiency in high-concurrency workloads. Developer Experience: Introduction of JSON_TABLE to facilitate JSON data manipulation and improvements to the MERGE command. Enhanced Logical Replication: Simplified upgrade process and greater resilience in high availability environments. Incremental backup: pg_basebackup now supports incremental backups and the new pg_combinebackup helps you rebuild full backups. The possibility of incremental backups fills one of the biggest shortcomings that the blue elephant had, bringing even more security to one of the best DBMS engines on the market.
