求助 关于Elasticsearch的circuit_breaking_exception的问题

今天发现往es插入数据开始报circuit_breaking_exception,具体报错为:

{"error":{"root_cause":[{"type":"circuit_breaking_exception","reason":"[parent] Data too large, data for [<http_request>] would be [763187340/727.8mb], which is larger than the limit of [727213670/693.5mb], real usage: [721261032/687.8mb], new bytes reserved: [41926308/39.9mb], usages [request=0/0b, fielddata=0/0b, in_flight_requests=41926308/39.9mb, accounting=1165885/1.1mb]","bytes_wanted":763187340,"bytes_limit":727213670,"durability":"TRANSIENT"}],"type":"circuit_breaking_exception","reason":"[parent] Data too large, data for [<http_request>] would be [763187340/727.8mb], which is larger than the limit of [727213670/693.5mb], real usage: [721261032/687.8mb], new bytes reserved: [41926308/39.9mb], usages [request=0/0b, fielddata=0/0b, in_flight_requests=41926308/39.9mb, accounting=1165885/1.1mb]","bytes_wanted":763187340,"bytes_limit":727213670,"durability":"TRANSIENT"},"status":429}

百度后大家都在说是因为fielddata过大的原因,但是经过我的配置后发现清空fielddata也不解决问题,配置如下图:


 
后来通过请求_nodes/stats/breaker?发现parent部分每次大批量插入数据都会变得非常大(如下),estimated_size甚至会超过limit,请问这个问题该如何解决.现在为es分配的内存为4g
