What kind of client are you using to connect to elasticsearch? Transport? Rest? ---

Just create one instance of the Transport client for the whole application and reuse that instance any time you need. It's thread safe. ---

thanks dadoonet. But in my application these methods should be connect to elasticserach simultaneously and do operations on indices, that's mean multi threads connect to elasticsearch at the same time and i have long delay for connecting to elasticsearch for every thread. What can be done to solve this problem? ---

> What can be done to solve this problem? Follow my advice. Share your Transport Client within your application please. You don't need to create multiple instances. ---
