Reduce memory peak when serializing to raw vectors
...serialize() to a raw vector:
df <- data.frame(runif(50e6,1,10))
ser <- serialize(df,NULL)
In this example the data frame and the serialized raw vector occupy ~400MB each, for a total of ~800M. However the memory peak during serialize() is ~1.2GB:
$ cat /proc/15155/status |grep Vm
...
VmHWM: 1207792 kB
VmRSS: 817272 kB
We work with very large data frames and in many cases this is killing R with an "out of memory" error.
This is the relevant code in R 3.1.3 in src/main/serialize.c:2494
InitMemOutPStream(&out, &mbs, type, version, hook, fun);
