modernc.org/cc@v1.0.1/v2/testdata/_sqlite/ext/repair/README.md (about)

     1  This folder contains extensions and utility programs intended to analyze
     2  live database files, detect problems, and possibly fix them.
     3  
     4  As SQLite is being used on larger and larger databases, database sizes
     5  are growing into the terabyte range.  At that size, hardware malfunctions
     6  and/or cosmic rays will occasionally corrupt a database file.  Detecting 
     7  problems and fixing errors a terabyte-sized databases can take hours or days,
     8  and it is undesirable to take applications that depend on the databases 
     9  off-line for such a long time.
    10  The utilities in the folder are intended to provide mechanisms for
    11  detecting and fixing problems in large databases while those databases
    12  are in active use.
    13  
    14  The utilities and extensions in this folder are experimental and under
    15  active development at the time of this writing (2017-10-12).  If and when
    16  they stabilize, this README will be updated to reflect that fact.
