Datastore Connectivity for Aerospike (asc)
This library is compatible with Go 1.5+
Please refer to CHANGELOG.md if you encounter breaking changes.
Usage:
The following is a very simple example of CRUD operations with dsc
config.yaml
driverName: aerospike
parameters:
namespace: test
host: 127.0.0.1
dateFormat: yyyy-MM-dd hh:mm:sspackage main
import (
_ "github.com/aerospike/aerospike-client-go"
_ "github.com/viant/asc"
"github.com/viant/dsc"
"log"
)
type Interest struct {
Id int `autoincrement:"true"`
Name string
ExpiryTimeInSecond int `column:"expiry"`
Category string
}
func main() {
config, err := dsc.NewConfigFromURL("config.yaml")
if err != nil {
log.Fatal(err)
}
factory := dsc.NewManagerFactory()
manager, err := factory.Create(config)
if err != nil {
log.Fatal(err)
}
// manager := factory.CreateFromURL("file:///etc/myapp/datastore.json")
interest := &Interest{}
success, err:= manager.ReadSingle(interest, "SELECT id, name, expiry, category FROM interests WHERE id = ?", []interface{}{id},nil)
if err != nil {
panic(err.Error())
}
var intersts = make([]*Interest, 0)
err = manager.ReadAll(&intersts, "SELECT id, name, expiry, category FROM interests", nil ,nil)
if err != nil {
panic(err.Error())
}
intersts = []*Interest {
Interest{Name:"Abc", ExpiryTimeInSecond:3600, Category:"xyz"},
Interest{Name:"Def", ExpiryTimeInSecond:3600, Category:"xyz"},
Interest{Id:"20, Name:"Ghi", ExpiryTimeInSecond:3600, Category:"xyz"},
}
_, _, err = manager.PersistAll(&intersts, "intersts", nil)
if err != nil {
panic(err.Error())
}
fmt.Printf("Inserted %v, updated: %v\n", inserted, updated)
deleted, err := manager.DeleteAll(&intersts, "intersts", nil)
if err != nil {
panic(err.Error())
}
fmt.Printf("Inserted %v, updated: %v\n", deleted)
var records = []map[string]interface{}{}
err = manager.ReadAll(&records, "SELECT id, name, expiry, category FROM interests", nil ,nil)
if err != nil {
panic(err.Error())
}
}Query level UDF support
- ARRAY converts supplied source column into collection of map entry defined as (key, value)
SELECT
id,
username,
ARRAY(city_visited) AS visited
FROM users- JSON convert supplied source column to JSON
SELECT
id,
username,
JSON(city_visited) AS visited
FROM usersGoCover
