Re: Transaction Cache vs. DB Cache Questions


Hi Joe,

just as Boxuan already said, the cache size is crucial for this task. But assuming your graph is large, only a fraction of the vertices will fit into the cache even if scaled appropriately. The problem that I see here is that for large graphs, the chance of finding a vertex in the cache is small, if you iterate over your queries in a random order. If you can come up with an execution order where vertices which have a similar 2-hop neighborhood are processed in temporal proximity to each other, that would greatly improve the cache hit rate.
