YugabyteDB, a distributed SQL database, offers various tips and tricks for efficient querying and data management. To update rows in a table based on values in another table, the PostgreSQL UPDATE join syntax can be used with the FROM clause. YugabyteDB supports namespaces and multiple applications can use a cluster without interfering with each other through role-based access control mechanisms. The statement_timeout parameter can be set to increase query timeouts, while disabling foreign keys temporarily allows for faster data import. New documentation, blogs, tutorials, and videos are available on the YugabyteDB website, covering topics such as PostgreSQL compatibility, data import, and getting started with the database. Upcoming events include free online training courses and certification opportunities.
