High Busy Buffer Waits in #PostgreSQL? It's a signal of I/O bottlenecks! 🚦 Busy buffers can slow down your queries and impact overall performance. Optimize your workload, tune shared buffers, and check for disk latency issues to keep your DB running smoothly! #DBA #SQL

🙋 So you both love #postgresql & DuckDB for their respective strengths (relational vs #olap) and respective ecosystems ❔ 💡What if I told you you can make them speak together from simple #sql 🎁 See how to achieve this, get even more productive (and play with #parquet files) https://lnkd.in/gYReDbKx #duckdb #database #dataengineering #productivity #tutorial

Did you know? in SQL, aggregation operators always return a single atomic value. #sql #postgresql #sqlserver

Hello everyone, just shared a new video on my YouTube channel! This time, I dive into the ProxySQL parameters "max_replication_lag" and "mysql-monitor_slave_lag_when_null". Understanding these parameters can be truly beneficial. I walk you through them with a practical demo. Feel free to drop your questions in the comments - I'll be more than happy to answer them. If you enjoy the content, don't forget to subscribe to my channel. Also, share it with your data enthusiast friends :) #mysql #database #dba #proxysql #replication Watch the video here: https://lnkd.in/gi9tdW3y

How do you choose the right Postgres table replica identity and what are the performance implications? Postgres tables require a replica identity to be configured in order to capture `update` and `delete` operations. Replica identity specifies the type of information written to the write-ahead log (WAL) with respect to the previous values. By default, replica identity uses the table’s primary keys. Our blog explains: 👉 How replica identity is an important part of database replication  👉 When to consider altering replica identity from `default` to `full` or `index` 👉 Performance implications of these changes Primarily, the decision is whether to use `default` or `full`. The decision really depends on the types of data and how tables are partitioned. Link to blog in comments. #dataengineering #datareplication #postgreSQL

In #postgresql... There is a CHECK constraint which enables you to specify a condition that must be met for each row in a table. As expected , a condition evaluates to TRUE or FALSE. If it is FALSE for any row, INSERT or UPDATE operation will be cancelled for that row and it may trigger an error. Though verbosity is my curse, I will let the code snippet below do the rest of the talking. ——— TL;DR: the CHECK constraint enforces business rules at the database level. This is a lot safer than dealing with handling these rules at the application level. #sql #databases

Every time I listen to this talk I pickup something I missed the last time. Like, linear scalability and 2.2 million QPS on an OLTP workload with 32 storage hosts ... wow, this is why I love TiDB https://lnkd.in/gbj8Su2q #DistributedSQL #MySQL #Sharding #OpenSourceDatabase
