>>>>>>>>> input
- I open an index, I read, I write, I optimize, and eventually the above
happens. The index is unusable.
- This has happened to me somewhere between 20 and 30 times now - on indexes of
different shapes and sizes.
- I don't know the reason. But, the following requirement applies regardless.
>>>>>>>>> requirement
- Like all modern database programs, there has to be a way to repair an index.
Period.
