... another random drop ...
ancient brute force tool-jumpmap.pl
generator, which runs about two hours here.
rows are pairs of from/to systemIDs, jumpcount and a route-is-highsec.
long highsec trumps short non-highsec.
unique key on sysid pairs.
both directions present.
no jumpcount cutoff.
the full jumpmap is about 27mil rows, with 510MB on-disk footprint (140 data, 370 index) in mysql here.
the zipped addon-mapJumps.sql.bz2
is about 80MB.
script is mysql, but again basic sql inserts so adapting to other sql flavors is trivial.
if you need to cut down the size, you may consider just deleting all rows with more than 50 jumps or so.
and dont forget to defrag/pack the table.
(and i have actualy run into sqlserver-side dijkstra before ... while investigating why a shared mysql server with some thousand users was doing about 150000 queries-per-second more than it was supposed to ... because someone forgot to add proper exit conditions ... :)
