ElasticSearch设置索引全局默认分片_elasticsearch 索引默认分片

设置全局分片数量：
put http://196.168.137.100:19085/_template/template_http_request_record
{
“index_patterns”: ["*"],
“settings”: {
“number_of_shards”: 5,
“number_of_replicas”: 1
}
}
指定创建索引时的分片数量：
put http://196.168.137.100:19085/<索引名称>
{
“settings”: {
“number_of_shards”: 12,
“number_of_replicas”: 1
}
}
client7.4.0创建索引时，指定主副分片

            //设置分片
            createIndexRequest.settings(
