Re: NDBCluster memory usuage
VARCHAR columns only store the size of the actual data, since the data is
UTF-8 it might be a bit bigger than the number of characters.
TEXT (BLOBs) columns store in chunks, first 256 bytes on main table and
then 2000 byte rows on a BLOB table.
So I gather you actually have more than 1 GByte in your database.
If you are ok with moving the data to disk (it works as long as you don't
need an index on the column) then it sounds like a good idea. Seems like
you have fairly large rows with lots of content, so gather those could
be good to place on disk. But depends on how much indexes you have.
Remember to also add some memory to the DiskPageBufferMemory such that
you can get fairly quick access to this data as well still.
