Activate 1.6 is a quick release that features an integration with the finagle-mysql non-blocking driver and some performance enhancements. Example code:

import net.fwbrasil.activate.ActivateContext
import com.twitter.finagle.exp.MysqlClient
import com.twitter.finagle.exp.MysqlStackClient
import com.twitter.finagle.client.DefaultPool
import com.twitter.util.TimeConversions.longToTimeableNumber
import net.fwbrasil.activate.storage.relational.async.FinagleMySQLStorage

object asyncFinagleMySQLContext extends ActivateContext {
    lazy val storage = new FinagleMySQLStorage {

        val dbPoolConfig = DefaultPool.Param(
            low = 10,
            high = 50,
            bufferSize = 0,
            idleTime = 100 millis,
            maxWaiters = 200)

         val client =
            new MysqlClient(MysqlStackClient.configured(dbPoolConfig))
                .withCredentials("user", "pass")
                .withDatabase("db_name")
                .newRichClient("host:port")
    }
}
