Queryparser, an Open Source Tool for Parsing and Analyzing SQL
You’re seeing information for Japan . To see local features and services for another location, select a different city. Show more In early 2015, Uber Engineering migrated its business entities from integer identifiers to UUID identifiers as part of an initiative towards using multiple active data centers. To achieve this, our Data Warehouse team was tasked with identifying every foreign-key relati
10 Cool SQL Optimisations That do not Depend on the Cost Model
Java, SQL and jOOQ. Best Practices and Lessons Learned from Writing Awesome Java and SQL Code. Get some hands-on insight on what's behind developing jOOQ. Cost Based Optimisation is the de-facto standard way to optimise SQL queries in most modern databases. It is the reason why it is really really hard to implement a complex, hand-written algorithm in a 3GL (third generation programming language)

Configuring sql.DB for Better Performance - Alex Edwards
There are a lot of good tutorials which talk about Go's sql.DB type and how to use it to execute SQL database queries and statements. But most of them gloss over the SetMaxOpenConns(), SetMaxIdleConns() and SetConnMaxLifetime() methods — which you can use to configure the behavior of sql.DB and alter its performance. In this post I'd like to explain exactly what these settings do and demonstrate t
