记录elastic4s客户端

Question

looking at this example

client.execute{search in "places"->"cities" query "paris" start 5 limit 10}

is there an option to hook logging to client.execute to log all operations made by the client (index, search etc') ?

I saw this answer but I do not want to do something like :

val req = search in "index" / "type" query "kate bush"
logger.debug(s"Search request ${req.show}")

I want the client to log all base on the logging level

You can define your own ElasticClient, with overriding execute functionality

object MyElasticClientFactory {
     def fromClient(client: Client): ElasticClient = new ElasticClient {
     def close(): Unit = client.close()
     def java: Client = client

     override def execute[T, R, Q](request: T)(implicit executable: Executable[T, R, Q]): Future[Q] = {
         // TODO your logging here
         super.execute(request)
     }

}

Take a look at TcpClient for reference https://github.com/sksamuel/elastic4s/blob/9a4074b6ff5616b648801352b4c3629cd0fc9020/elastic4s-tcp/src/main/scala/com/sksamuel/elastic4s/TcpClient.scala
