README.md

This folder contains extensions and utility programs intended to analyze live database files, detect problems, and possibly fix them.

As SQLite is being used on larger and larger databases, database sizes are growing into the terabyte range. At that size, hardware malfunctions and/or cosmic rays will occasionally corrupt a database file. Detecting problems and fixing errors a terabyte-sized databases can take hours or days, and it is undesirable to take applications that depend on the databases off-line for such a long time. The utilities in the folder are intended to provide mechanisms for detecting and fixing problems in large databases while those databases are in active use.

The utilities and extensions in this folder are experimental and under active development at the time of this writing (2017-10-12). If and when they stabilize, this README will be updated to reflect that fact.
