这是我的连接文件
this IServiceCollection services, IConfiguration configuration)
{
var EsNode = configuration["elasticsearch:AcqDataUrl"];
var NCTNode = configuration["elasticsearch:NCTDataUrl"];
var nodes = new Uri[]
{
new Uri(EsNode),
new Uri(NCTNode)
};
var pool = new StaticConnectionPool(nodes);
var connection = new ConnectionSettings(pool).DisableDirectStreaming();
EsClient = new ElasticClient(connection);
var settings = new IndexSettings { NumberOfReplicas = 1, NumberOfShards = 2 };
var indexConfig = new IndexState
{
Settings = settings
};
在这里,我想定义应该在哪个节点上创建索引,即它在第一个节点上创建索引的多个节点之间的节点[0]或节点[1]
{
EsClient.Indices.Create(configuration["elasticsearch:AcquiringIndex"], c => c
.InitializeUsing(indexConfig)
.Mappings(m => m.Map<Acquirer>(mp => mp.AutoMap())));
}
if (!EsClient.Indices.Exists(configuration["elasticsearch:ElasticR&DIndex"]).Exists)
{
EsClient.Indices.Create(configuration["elasticsearch:ElasticR&DIndex"], c => c
.InitializeUsing(indexConfig)
.Mappings(m => m.Map<Employee>(mp => mp.AutoMap())));
}
if (!EsClient.Indices.Exists(configuration["elasticsearch:NetConnectTransactionIndex"]).Exists)
{
EsClient.Indices.Create(configuration["elasticsearch:NetConnectTransactionIndex"], c => c
.InitializeUsing(indexConfig)
.Mappings(m => m.Map<TransactionDto>(mp => mp.AutoMap())));
}
services.AddSingleton<IElasticClient>(EsClient);
}
我想从singleton开始传递这两个连接,并在startup.cs中调用它,因为它将在继承控制器的类中使用,以便进一步查询

如果创建了一个包含2个主碎片和1个副本的索引,并且有2个数据节点,则两个节点上都有碎片[0]和碎片[1](因为每个碎片有2个副本,而副本不能位于同一个节点上),接收create index api调用的节点与确定碎片的位置无关
