InterSystems Caché vs. LevelDB vs. TypeScript vs. phpMoAdmin Comparison Chart

LevelDB is a fast key-value storage library written at Google that provides an ordered mapping from string keys to string values. Keys and values are arbitrary byte arrays. Data is stored sorted by key. Callers can provide a custom comparison function to override the sort order. Multiple changes can be made in one atomic batch. Users can create a transient snapshot to get a consistent view of data. Forward and backward iteration is supported over the data. Data is automatically compressed using the Snappy compression library. External activity (file system operations etc.) is relayed through a virtual interface so users can customize the operating system interactions. We use a database with a million entries. Each entry has a 16 byte key, and a 100 byte value. Values used by the benchmark compress to about half their original size. We list the performance of reading sequentially in both the forward and reverse direction, and also the performance of a random lookup.

Sort by any key within your data object (even nested sub-keys!) with ascending/descending option. Define the number of results to display per page (or unlimited). Option to enable password protection for one or more users; to activate protection, just add the username-password(s) to the array at the top of the file. Works on any version of PHP5 with the MongoDB NoSQL database & Mongo PHP driver.
