It's a simple request for a search api, am I right ? So I wrote a code for this. Here it is; private static void Search(IElasticContext elasticContext, string indexName) { IQueryContainer termQueryContainer = new

Elastic Load Balancing 提供了三种可用于 CodeDeploy 部署的负载均衡器：Classic Load Balancer、Application Load Balancer 和 Network Load Balancer。 传统负载均衡器 路由和负载均衡在传输层 (TCP/SSL) 或应用程序层 (HTTP/HTTPS) 进行。它支持 EC2-Classic 或 VPC。 应用程序负载均衡器 路由和负载均衡在应用程序层 (HTTP/HTTPS) 进行，并支持基于路径的路由。它可以将请求路由到您的 Virtual Private Cloud (VPC) 中每个 EC2 实例或容器实例上的端口。 注意 应用程序负载均衡器 目标组必须有一个目标类型 instance； Network Load Balancer 路由和负载均衡在传输层（TCP/UDP 层，即第 4 层）进行，依据是从 TCP 数据包标头中而非从数据包内容中提取的地址信息。Network Load Balancer 可以处理突发流量、保留客户端的源 IP 以及在负载均衡器的使用寿命内使用固定 IP 负载均衡器在 CodeDeploy 部署中的作用 在 CodeDeploy 部署期间，负载均衡器会阻止 Internet 流量路由到未就绪的实例，目前正在部署的实例，或环境不再需要的实例。但是

codedeploy概述： codedeploy是aws上面的一个自动部署服务，可以自动的将应用程序部署到EC2实例、本地实例（任意的线上或线下自己的一台机器）、无实例的lamda函数、ECS上面。 可以部署的应用程序包括：代码、无服务器的lamda函数、web和配置、可执行文件、包、脚本、多媒体文件。 可以部署到一个或数千个实例。 CodeDeploy提供了两种部署类型选项： 1）就地部署：停止部署组中每个实例上的应用程序，安装最新的应用程序修订版，并启动并验证新版本的应用程序。您可以使用负载平衡器，以便在部署期间取消注册每个实例，然后在部署完成后恢复为服务。只有使用EC2 / On-Premises计算平台的部署才能使用就地部署。 工作原理：创建可部署的内容，添加 应用程序规范文件 （AppSpec文件：定义了CodeDeploy执行的部署操作），将可部署内容和AppSpec文件捆绑到存档文件中，然后上传到s3或github中，此时的归档文件称为 应用程序修订版 --> 告诉codedeploy新代码或部署内容在哪，codedeploy调用一组EC2 --> 每台EC2上面的EC2实例轮询codedeploy，确定在哪获得新的内容和时间 --> 每个实例上的CodeDeploy代理从S3或GitHub上提取新代码，并使用AppSpec文件中的指令将内容部署到实例。 2）

Basically, I have a data set consisting of data in the following form: { "name": "The Chef Restaurant", "city": "New York", "state": "New York", "rating": "GOOD", "type": "Continental" } Now, I want to do some aggregation and get all the Continental restaurants, Good restaurants, Restaurants in New York in one query. Note that I don't want the count of all types of restaurants, I just want the count of the specific types. Also, these aggregations are

Using postman, I was able to test this flow on my localhost and everything works fine. However, I'm having issues now that I moved it to Elastic Beanstalk. When I post to the endpoint, it uploads a blank file to S3 and there are no errors logged in EB. I think it has something to do with the software but am a bit stuck. Any advice appreciated! Thanks!

It exceeds the default 8GB capacity of the EBS disk on the EC2 instances. I tried to increase the disk capacity by using a bigger EC2 instance type. For instance, I used an m3.large, which AWS tells me should provide me with 1x32GB of storage. However, when the Beanstalk environment launches, it still only shows 8GB. I tried to run the "resize2fs" command on the instance, but it didn't expand the volume to anything over 8GB. Does anyone know how to get

The error I have is the following : Set update_all_types to true to update [search_quote_analyzer] across all types.] But I am not able to find a single reference on how or where to set this 'update_all_types' parameter.
