##MongoDB streaming collection 
gopkg.in/mgo.v2.
It adds functionality to
- Check if a collection exist
- Convert an uncapped collection to a capped one
- A constructor like function, which returns a capped collection
- Get a collection's stats
- Query a capped collection and stream documents out of it into a channel
Installation
go get github.com/ballad89/mgoStreamingCollection
Example Usage
Examples of how to use the individual functions can be seen in the test file Below is an example of how you would use it in a program
package main
import (
"fmt"
"gopkg.in/mgo.v2"
"github.com/ballad89/mgoStreamingCollection"
)
func main() {
connectUrl := "mongodb://33.33.13.45/streamingDb"
session, err := mgo.Dial(connectUrl)
if err != nil {
panic(err)
}
session.SetSafe(&mgo.Safe{})
defer session.Close()
collectionName := "cappedCollection"
collectionSize := 1024
database := session.DB("streamingDB")
cappedCollection, err := mgoStreamingCollection.CreateOrConvertCollection(database, collectionName, collectionSize)
if err != nil {
panic(err)
}
ch := make(chan interface{})
go mgoStreamingCollection.TailQuery(cappedCollection.Find(nil), ch)
for msg := range ch {
fmt.Println(msg)
}
}
