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. |
