Documentation

If you are new to SlicingDice, check our quickstart guide and learn to use it in 15 minutes.

Please refer to the SlicingDice official documentation for more information on how to create a database, how to insert data, how to make queries, how to create columns, SlicingDice restrictions and API details.

Tests and Examples

Whether you want to test the client installation or simply check more examples on how the client works, take a look at tests and examples directory.

Installing

In order to install the Go client, you only need to execute the go get command.

go get github.com/SlicingDice/slicingdice-go/slicingdice

Usage

The following code snippet is an example of how to add and query data using the SlicingDice GO client. We entry data informing user1@slicingdice.com has age 22 and then query the database for the number of entities with age between 20 and 40 years old. If this is the first record ever entered into the system, the answer should be 1.

package main

import (
    "fmt"
    "github.com/SlicingDice/slicingdice-go/slicingdice"
)

func main() {
    // Configure client
    keys := new(slicingdice.APIKey)
    keys.MasterKey = "YOUR_API_KEY"
    client := slicingdice.New(keys, 60)

    // Inserting data
    insert_data := map[string]interface{}{
        "user1@slicingdice.com": map[string]int{
            "age": 22,
        },
        "auto-create": []string{"dimension", "column"},
    }
    client.Insert(insert_data)

    // Querying data
    query_data := map[string]interface{}{
            "query-name": "users-between-20-and-40",
            "query": []map[string]interface{} {
                map[string]interface{}{
                    "age": map[string][]int{
                        "range": []int{20, 40},
                    },
                },
            },
    }

    result, _ := client.CountEntity(query_data)
    fmt.Println(result["status"])
}

Reference

SlicingDice encapsulates logic for sending requests to the API. Its methods are thin layers around the API endpoints, so their parameters and return values are JSON-like interface{} objects with the same syntax as the API endpoints

Attributes

• key (map[string]string) - API key to authenticate requests with the SlicingDice API.
• timeout (int) - Amount of time, in seconds, to wait for results for each request.

Constructors

New(key *APIKey, timeout int) *SlicingDice

• key (APIKey) - API key to authenticate requests with the SlicingDice API.
• timeout (int) - Amount of time, in seconds, to wait for results for each request.

GetDatabase()
