I am just trying to get a handle on when tables are physically written to disk. (ignoring
whatever operating system level caching that may be going on)
IE If you do some updates/inserts to a MyIsam table and then have a power failure will you
ALWAYS loose those updates (Even if the power failure is after say 5 minutes of inactivity
on a table, assuming no intervening FLUSH command), or does the server do a write to disk
based on some algorithm (eg low activity or Number of updates)?
I understand the operating system may do its own caching and hence have a bearing on this
- but at this stage I just need to know how/when MySql Physically writes the tables to
