    SQLCheck

    SQLCheck

    Automatically identify anti-patterns in SQL queries

    sqlcheck automatically detects common SQL anti-patterns. Such anti-patterns often slow down queries. Addressing them will, therefore, help accelerate queries. Storing a list of IDs as a VARCHAR/TEXT column can cause performance and data integrity problems. Querying against such a column would require using pattern-matching expressions. It is awkward and costly to join a comma-separated list to matching rows. This will make it harder to validate IDs. Think about what is the greatest number of...

    levelup

    levelup

    A wrapper for abstract-leveldown compliant stores, for Node.js

    ...LevelDB stores entries sorted lexicographically by keys. This makes the streaming interface of levelup - which exposes LevelDB iterators as Readable Streams, a very powerful query mechanism. The most common store is leveldown which provides a pure C++ binding to LevelDB. Many alternative stores are available such as level.js in the browser or memdown for an in-memory store. They typically support strings and Buffers for both keys and values. For a richer set of data types you can wrap the store with encoding-down.
