Re: Write Behind Performance

[afedotov <al...@gmail.com>]

Hi Rick,

1) As for now, there is no API for checking write-behind queue size. In any
case, such method would provide only an approximate result.
2) You should carry out some testing to figure out the appropriate balance
between the batch size and flush frequency that will fit your particular
case.There is no rule of thumb and each particular case should be treated
specifically.
If the underlying DB is able to cope with a high write rate then you could
try setting a decent batch size and flush frequency size <times> * <avg DB
write rate>, where <times> depends on your cache-to-DB synchronization
requirements.

Kind regards,
Alex
