Go client for RexPro/Rexster
with connection pooling as well as support for sessions. Compatable with RexPro
protocol version 1 (Rexster v2.4.0 and above at the time of this writing).
import "github.com/philipsoutham/gorexpro/rexpro"func main() {
var properties = map[string]interface{}{"properties": map[string]interface{}{"foo": "bar", "score": 5}}
if c, err := rexpro.Dial("your-host:8184", "your-graph-name"); err == nil {
defer c.Close()
if resp, err := c.DoScript("g.addVertex(properties)", properties); err == nil {
doSomethingWith(resp)
}
}
}var RexproPool *rexpro.Pool
func init() {
RexproPool = &rexpro.Pool{
MaxIdle: 5,
MaxActive: 200,
IdleTimeout: 25 * time.Second,
Dial: func() (rexpro.Conn, error) {
return rexpro.Dial("your-host:8184", "your-graph-name")
},
TestOnBorrow: func(c rexpro.Conn, t time.Time) error {
_, err := c.DoScript("1", map[string]interface{}{})
return err
},
}
}
func main() {
var (
c = RexproPool.Get()
properties = map[string]interface{}{"properties": map[string]interface{}{"foo": "bar", "score": 5}}
)
defer c.Close()
if resp, err := c.DoScript("g.addVertex(properties)", properties); err == nil {
doSomethingWith(resp)
}
}
Polishing them now, so coming soon (hopefully er, maybe)
Right now, some assumptions are made in regards to the isolate parameter in the script request Meta map;
that is to say that if you are in a "session", isolate will be set to false and inSession will be set to true.
If you're not in a "session" the inverse will be applied. Also, the graphObjName parameter is always hardcoded to "g".
to @garyburd as I have copied much of the API he created for his excellent redigo redis client and will be also leveraging his hard work for the unit tests as well.
