How many vertex & edges can be added into a graph?

[wen-bing]

Hi

When I try to use load_labels_from_file to import vertex from a csv file, I got an error said:

pq: entry_id must be 1 .. 281474976710655

the vertex's id in csv is a uint64_t integer value.

if I change the id to a uint32_t，then all vertex in csv can be loaded succedded.

Is this means the maximum vertex number is 281474976710655 ?

Yes, and that is the maximum for edges too. Though, this limitation applies per graph.

OK,
Just worndering why not use 64 bits length

@wen-bing The actual ID is only 48 bit. Rest of the 16 bit is reserved for label ID to gain some performance benefits. Do you need to store more than 281474976710655 vertices?
