[C++] How can I read streaming parquet file in v0.15.0

[annsshadow]

hi~
I hava a question about reading parquet file.
The offical example is reading the whole file from the local.
Now I can't get the whole parquet file in the memory, only can fetch it slice 
by slice from the network, so how can I use arrow to read the parquet file?
thank you~
