aerospike-scala-dsl

N|Solid

To start working with Aerospike using this DSL you have to add dependency sbt:

"ru.tinkoff" %% "aerospike-scala" % "1.1.14",
"com.aerospike" % "aerospike-client" % "3.3.1", // in case you don't have it
"ru.tinkoff" %% "aerospike-scala-example" % "1.1.14" // usage examples
"ru.tinkoff" %% "aerospike-scala-proto" % "1.1.14" // protobuff serialization support

Since I'm using Aerospike Java Client (version 3.3.1, recomended on www.aerospike.com), you need to create com.aerospike.client.async.AsyncClient to pass it into ru.tinkoff.aerospike.dsl.SpikeImpl class. SpikeImpl has methods to operate with Aerospike for specified types of Keys and Bins, which is the most common case. Example for that object creation you can find in ru.tinkoff.aerospikeexamples.example.AClient (sh "ru.tinkoff" % "aerospike-scala-example"). Or just follow the quickstart instructions.

#Protobuf Serialization is here! Check it out!

Quickstart

Add this settings to application.conf file and specify your own host, port, namespace and setName:

ru-tinkoff-aerospike-dsl {
    keyWrapper-namespace = "test"
    keyWrapper-setName = "test"
    example-host = "somehost.com" 
    example-port = 3000
}

after that call ru.tinkoff.aerospikeexamples.example.AClient.client in your service (or something where you need to communicate with Aerospike) and pass result of that call into ru.tinkoff.aerospike.dsl.SpikeImpl:

import scala.concurrent.ExecutionContext.Implicits.global

val client = AClient.client
val spike = new SpikeImpl(client)

or you can call AClient.spikeImpl, which gives an example of SpikeImpl with host and port from ru-tinkoff-aerospike-dsl settings

 val spike = AClient.spikeImpl

Note: don't forget to add host and port in application.conf, or you will get an exception from com.aerospike.client lib:

Exception in thread "main" com.aerospike.client.AerospikeException$Connection: Error Code 11: Failed to connect to host(s): 
host 3000 Error Code 11: Invalid host: host 3000

For namespace and setName parameters add

implicit val dbc = AClient.dbc

Now you can use it like this:

import ru.tinkoff.aerospike.dsl.{CallKB, SpikeImpl}
import ru.tinkoff.aerospikeexamples.example.AClient
import ru.tinkoff.aerospikescala.domain.SingleBin
import ru.tinkoff.aerospikemacro.converters._

import scala.concurrent.Await
import scala.concurrent.duration.Duration
import scala.concurrent.ExecutionContext.Implicits.global

object HelloAerospike extends App {

  val client = AClient.client
  val spike = new SpikeImpl(client)
  implicit val dbc = AClient.dbc

  Await.result(spike.callKB(CallKB.Put, "testKey", SingleBin("helloName", "helloValue")), Duration.Inf)
}

This will Put string value "helloValue" with name "helloName" in Aerospike with Key "testKey". For that call will be generated converters, both to convert passed values into inner com.aerospike.clients values.

aql> select * from test.test
[
  {
    "helloName": "helloValue"
  }
]

All available methods you can see in SpikeImpl class by your self. For more information and usage examples cookbook.

DSL schema options

In ru.tinkoff.aerospike.dsl.scheme we have two traits:

  • for work with one key type and different types of Bins
trait Scheme[K]
  • for work with one key type and one Bin type
trait KBScheme[K, B]

If you want to work with one type of Key and different types of Bins - any Bin types If you want to work with one type of Key and one type of Bins one Bin type

Application

Implemented for ASyncClient. Recommended to use with Aerospike 3.
