The document discusses the concept of cognitive load in software development, emphasizing its significance in reducing confusion for developers. Confusion leads to wasted time and money and is primarily caused by high cognitive load, which refers to the mental effort required to complete tasks, especially when reading and understanding code. The author notes that developers often spend more time reading than writing code and highlights the importance of managing cognitive load to enhance comprehension. Cognitive load is categorized into two types: intrinsic load, which cannot be reduced and is inherent

The summary discusses a study on improving the speed of SQLite for analytical queries by leveraging Bloom filters, making it up to ten times faster. SQLite, a B-tree structured, row-based storage database, primarily excels in OLTP (Online Transaction Processing) workloads but was found to lag behind DuckDB in handling analytical queries, specifically those adhering to the Star Schema Benchmark (SSB), which includes complex joins between large fact tables and smaller dimension tables. Researchers discovered that SQLite's performance issues stemmed from certain op

The content discusses how researchers enhanced SQLite's performance for analytical queries by implementing Bloom filters, making it 10 times faster. It summarizes the findings from the paper "SQLite: Past, Present, and Future" (2022) and provides an overview of SQLite's architecture, which uses a B-tree on disk for row-based storage and a virtual machine (VDBE) to execute queries. Although SQLite generally excels in Online Transaction Processing (OLTP) workloads, a study from Buffalo University in 201

The author discusses the N+1 query problem, which occurs when a single database query is followed by multiple additional queries for associated records as each object is processed. This is a prevalent issue in web applications, often leading to performance degradations. The author illustrates this with an example involving a Product model that lazily loads associated data, resulting in a series of database queries (1 initial query plus N lazy loads). They emphasize the commonality of this issue, noting its prevalence second only to forgotten indexes in

The article discusses the importance of routinely inspecting the performance of SQL statements in a PostgreSQL instance by using the `pg_stat_statements` view. This view provides statistics about executed SQL statements, including the `shared_blks_dirtied` and `shared_blks_written` columns, which track how many data blocks in the shared buffer cache are modified and written to disk. An interesting point noted is that even simple SELECT queries can yield non-zero values in these columns, suggesting that read-only statements can
