Large file issue: process out of memory

[adaromu]

I'm trying to convert a 800MB shapefile to TopoJSON format, topojson -q 1e4 -s 1e-8 -p zip=ZCTA5CE10 -o zips_us_topo_zc.json tl_2012_us_zcta510.shp

Every time, when the node memory exceeds 1.99G, it terminated. And shows the information:

FATAL ERROR: CALL_AND_RETRY_2 Allocation failed - process out of memory
Abort trap: 6

To change the max stack size, I have tried topojson -q 1e4 -s 1e-8 -p zip=ZCTA5CE10 -o zips_us_topo_zc.json tl_2012_us_zcta510.shp --max-stack-size=10737418240 or topojson -q 1e4 -s 1e-8 -p zip=ZCTA5CE10 -o zips_us_topo_zc.json tl_2012_us_zcta510.shp --stack-size=10737418240 , but none of them work.

Local Enviroment:

node v0.10.26
topojson v1.6.9

Is there a way I can add the memory for topojson or other ways to convert these kind large files to topojson format? Thanks!

Find solution from another ticket: #71
Change the command line to

node --max_old_space_size=8192 `which topojson` -q 1e4 -s 1e-8 -p zip=ZCTA5CE10 -o zips_us_topo_zc.json tl_2012_us_zcta510.shp

It works!

Btw, thanks for your great work on map!
