fastest native python database?

[per]

hi all,

i'm looking for a native python package to run a very simple data
base. i was originally using cpickle with dictionaries for my problem,
but i was making dictionaries out of very large text files (around
1000MB in size) and pickling was simply too slow.

i am not looking for fancy SQL operations, just very simple data base
operations (doesn't have to be SQL style) and my preference is for a
module that just needs python and doesn't require me to run a separate
data base like Sybase or MySQL.

does anyone have any recommendations? the only candidates i've seen
are snaklesql and buzhug... any thoughts/benchmarks on these?

any info on this would be greatly appreciated. thank you
