Connecting to Redis Cluster from Spring Boot caching abstraction

I am using Spring Boot with Caching abstraction support to connect to redis-server for storing/fetching data for caching.
I use the below properties for connecting to redis-server.
spring.redis.host=localhost
spring.redis.port=6379
spring.redis.password=mypassword
spring.cache.type=redis
I am able to successfully connect to redis server and store/fetch data.
For high availability,it is decided to use 3 nodes , 1 master and 2 slave nodes for redis server.
In that case, I am not sure how to provide the configuration to connect to redis cluster from my spring boot application.
Are there any properties supported by spring boot to connect to redis cluster.
I am using out-of-box support of spring caching abstraction with support for annotation #cacheable.
I have the below 2 dependencies added to my pom.xml
spring-boot-starter-cache and spring-boot-starter-data-redis
and also using spring boot 1.5.13.
Is there support for connecting to redis cluster when using spring caching abstraction in spring boot.

HiKariCP for Bigquery

I am new to gcloud and trying to leverage bigquery for accessing the data. I am trying to implement a connection pooling mechanism for bigquery and found that Hikari (one of the default datasource provided by spring boot) as a viable option. Could you please guide me in setting up the Bigquery credentials in the Hikari datasource as I am not able to figure out the way to give the driver, url and credentials.
I imported the bigquery api and hikari api in my pom dependencies
FYI: I am trying to make use of springboot
I have managed to establish connection from spring boot to bigquery using simba JDBC drivers and successfully queried it.
Firstly, you need to include GCP starter dependency in your boot.
<artifactId>spring-cloud-gcp-dependencies</artifactId>
Dowload and add dependency jars of simba drivers in spring boot from the below link. Also refer installation guide in the link.
https://cloud.google.com/bigquery/docs/reference/odbc-jdbc-drivers
Secondly, create a service account that has access to bigquery and generate a key JSON file which is used to authenticate our spring boot application for connecting bigquery. Refer the below link.
https://cloud.google.com/bigquery/docs/reference/libraries#setting_up_authentication.
Lastly configure this key JSON file to be accessed by our spring book application using the simba driver JDBC installation guide.
Create a simba driver datasource and use this data source to create JDBC template bean. ( JDBC url formation is given in the installation guide of simba driver) . Thats it!! Run the application and see the results.
If you face any difficulties feel free to ask the specifics.

How do I setup connection pooling in spring boot for Elasticsearch

I have created a spring boot application that uses spring boot starter data elasticsearch to connect to elasticsearch. I want to configure this application to setup connection pooling. How do I configure the application.properties to support it?
Old answer. Since Boot 2.2, the reactive client doesn't have these options.
From the docs:
spring.data.elasticsearch.properties.*= # Additional properties used to configure the client.
Though it does appear that the default TransportClient does pool connections anyway.
