Elasticseach调增部分参数

1、调整参数

curl -XPUT 'http://172.20.43.6:9200/_cluster/settings' -d '{ 

    "persistent": {

        "indices.recovery.max_bytes_per_sec" : "50mb",

        "threadpool.index.type": "fixed",

        "threadpool.index.queue_size": 80000,

        "threadpool.index.size": 90,

        "threadpool.search.size": 90,

        "threadpool.search.type": "fixed",

        "threadpool.search.queue_size":80000,

        "threadpool.flush.size": 32,

        "indices.memory.index_buffer_size": "20%",

        "index.translog.durability": "async",

        "index.translog.flush_threshold_size": "600MB",

        "index.translog.flush_threshold_ops": 500000

    },

"transient": {

'{

    "transient": {

        "logger.discover": "DEBUG"

    }

    "persistent": {

        "discovery.zen.minimum_master_nodes": 2

    }

}'
