Re: NDBCluster memory usuage
From the configuration one can conclude that you have around 6M rows in your
database (around 15 bytes of IndexMemory per row).
If you have 1 GByte data size then your rows are around 170 bytes per row.
There is a around 24 bytes of overhead per row and another around 15 bytes
per row per ordered index. Given that your DataMemory uses about 16GB of
memory one can conclude that you use about 2670 bytes per row. So it takes
quite a few indexes to reach this.
Other things you could be doing is that you could have defined some
attribute types as fixed size strings or you could have a lot of
BLOBs that doesn't store any data.
So look in your schema for solutions. It could also be related to data
that was inserted and later deleted.
