There are Go example codes in this directory.
All example codes use go-gir-generator to use Arrow GLib based bindings.
See ../../README.md how to install Arrow GLib. You can use packages to install Arrow GLib. The following instructions assumes that you've installed Arrow GLib by package. Package name is libarrow-glib-dev
on Debian GNU/Linux and Ubuntu, arrow-glib-devel
on CentOS.
Here are command lines to install go-gir-generator on Debian GNU/Linux and Ubuntu:
% sudo apt install -V -y libarrow-glib-dev golang git libgirepository1.0-dev libgudev-1.0-dev % export GOPATH=$HOME % go get github.com/linuxdeepin/go-gir-generator % cd $GOPATH/src/github.com/linuxdeepin/go-gir-generator % make build copyfile % mkdir -p $GOPATH/bin/ % cp -a out/gir-generator $GOPATH/bin/ % cp -a out/src/gir/ $GOPATH/src/
Now, you can generate Arrow bindings for Go:
% git clone https://github.com/apache/arrow.git ~/arrow % cd ~/arrow/c_glib/example/go % make generate
Then you can build all example codes:
% cd ~/arrow/c_glib/example/go % make % ./write-batch # Write data in batch mode % ./read-batch # Read the written batch mode data % ./write-stream # Write data in stream mode % ./read-stream # Read the written stream mode data
Here are example codes in this directory:
write-batch.go
: It shows how to write Arrow array to file in batch mode.
read-batch.go
: It shows how to read Arrow array from file in batch mode.
write-stream.go
: It shows how to write Arrow array to file in stream mode.
read-stream.go
: It shows how to read Arrow array from file in stream mode.
