Hi guys. Sorry to come back with this old post, but now I am interested ;)
Right now, I have a requirement where I need to write a graph into a file. I
am using Fuel for that. Each graph, has its own file. In the image side I
just store the filename, When I need to load it it reads such file and
materialize it with Fuel. I was thinking going a step forward and use a
key/value (a.k.a no-sql) database.
With Fuel, I can take a graph, and serialize directly into a ByteArray,
hence I can take a graph to swap, I assign an ID, and and save it into the
database. In the image side, I keep that ID. Then, when needed, I search it
in the database and then after with that ByteArray found, I materialize it
So...first question is, do you think that could be faster/better than
directly writing into a file as I am doing now?
Now, which are the available Pharo wrappers for no-sql databases that let me
do that? I would appreciate any link or documentation about them. What do
I need to use such databases from Pharo? FFI and a library installed in my
machine? are there binaries for Mac OS?
Thanks in advance,
