[GraphHopper] Out of memory at graph creation

[Nicolas Gillet]

Hello,

I'm facing an OutOfMemoryError (heap space) when creating a bigger graph.
Actually, I am creating a graph out of our own data source including speed profile definitions on the Belgian territory.
Creating a simple graph works fine but when it comes to create the speed profiles, my process quickly runs out of memory.
To store these speed profiles, I have created 7 more DataAccess, one for each day of week and each edge has one speed profile stored in there.
I'd like to know if there could be a way to flush the DataAccess on a regular basis to release memory.

When I see that you managed to create a worldwide graph, I guess there might be such mechanism but I couldn't find it.

Thank you

Nicolas GILLET
