I spent some time on searching info on how I can check if an index exists, but failed. If it's possible with the current library state, could you please show me an example? If not, can we add it?

接下来,我们创建一个叫做 my-audio-index 的索引: index_name = "my-audio-index" if(es.indices.exists(index=index_name)): print("The index has already existed, going to remove it") es.options(ignore_status=404).indices.delete(index=index_name) # Specify index configuration mappings = { "...
leader_check 失败多少次会认为leader检测失败, 默认3次, 超过这个次数之后,节点认为当选的主节点有故障并尝试查找或选举新的主节点 💡 注意事项: 选出的主节点检测到某个节点已断开连接,这种情况会被立即认为是故障,主节点绕过超时和重试设置值并尝试从集群中删除节点。
leader check 和 follower check 实际上都是线程,由 same 线程池执行,same 线程池是一种DIRECTl类型的线程池,当某个任务不需要在独立的线程执行,又想被线程池管理时,于是诞生了这种特殊类型的线程池: 在调用者线程中执行任务,这个same线程池是对用户不可见的,所以通过_cat/thread_pool看不到这个线程池。
