【随笔】一个ES circuit_breaking_exception问题的解决

Docker下面运行的ES在运行了一段时间以后在跑任何query的时候都报错：

{
  "error" : {
    "root_cause" : [
      {
        "type" : "circuit_breaking_exception",
        "reason" : "[parent] Data too large, data for [] would be [`1004465832/957.9mb`], which is larger than the limit of [`986061209/940.3mb`]",
        "bytes_wanted" : 1004465832,
        "bytes_limit" : 986061209
      }
    ],
    "type" : "circuit_breaking_exception",
    "reason" : "[parent] Data too large, data for [] would be [1004465832/710.9mb], which is larger than the limit of [745517875/710.9mb]",
    "bytes_wanted" : 1004465832,
    "bytes_limit" : 986061209
  },
  "status" : 503
}

网上搜了一下是内存不够了，之前的compose文件里面的Java启动内存参数是：

 - "ES_JAVA_OPTS=-Xms512m -Xmx512m"

把里面的512m改成2048m 。然后docker-compose重启ES集群就解决问题了。
