Hi,
I've a similar problem: I'm doing a university thesis and I aim to provide a better sinergy between Grass and MySQL (using the fast all in memory engine); after reading a lot of the mysql source code, I found that heap engine doesn't support Gis Data because of the its absence of Blob support, through which GIS data are, at the moment, memorized. I also found that blob data aren't supported because memory engine has a fixed row format, which is incompatible with blobs.
We could cooperate to add this feature to the heap engine, coudn't we?
In Ingo's answer it is said that it could be a non trivial task: but why? Aren't blob inserted in tables through a memory pointer, now? I now can see just a memory saturation possibility in case of intensive use of blobs. And what about ndb blob implementation?
I hope to read of you soon...
Manu
