Comment 4 for bug 1269547

Laurynas yes, that is what I have in mind.

Even increasing the size of and making the bitmaps variable length would not help much for us. We perform small random writes to a very large table. At its worst, the ratio between LSN delta divided by bitmap size was around 5, but got worse as the db size increased. The end size of the db was around 300GB.

I'm attaching the output from "ls -ltr /var/lib/mysql | grep xdb" that should give the info you requested.
