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.

I am migrating a existing Spring application (non Spring boot) to Springboot 2.x. I see there is a c3p0.properties file with following configuration: com.mchange.v2.c3p0.management.ExcludeIdentityToken=true. What does this does exactly? Do I need this if I am using Springboot 2.x? Or do I need to setup something else configuration in my application.properties file?
Thank you for help.
Spring Boot 2.x use HikariCp as a default JDBC connection pool. It is faster then c3p0.
You should use Hikari.
You can read about it compared with c2p0:
Hikari vs other CPs
Spring Boot will autoconfig it to you, but you can customize it (for example in application.properties)
For the com.mchange.v2.c3p0.management.ExcludeIdentityToken visit the documentation page's Jmx configuration section
JMX configuration
How to check what is the connection pool being used by default. I am using Spring boot version 1.5.4.RELEASE
UPDATE : https://www.mkyong.com/spring-boot/spring-boot-how-to-know-which-connection-pool-is-used/
Spring Boot uses HikariCP as the default connection pool, due to its remarkable performance and enterprise-ready features.
Here’s how Spring Boot automatically configures a connection pool datasource:
Spring Boot will look for HikariCP on the classpath and use it by
default when present
If HikariCP is not found on the classpath, then Spring Boot will pick
up the Tomcat JDBC Connection Pool, if it’s available
If neither of these options is available, Spring Boot will choose
Apache Commons DBCP2, if that is available

I am using Spring boot + MySQL + Data JPA.
When I started my spring boot app, its taking initial pool size as 10.
I have tried to customize it using following property:
spring.datasource.dbcp2.initial-size=20
But its not working. How to fix this ?
If you don't configure your Connection Pool, Spring Boot will pick HikariCP at default. The connection pool for HikariCP can be configured as following:
spring.datasource.hikari.maximum-pool-size=5
My microservices are using the latest releases of Spring Boot, Spring WebFlux (Undertow), Spring Data MongoDB, Spring Cloud Netflix, and Kotlin...
Now I've setup a demo project to use the new functional interface instead of the annotations in Spring WebFlux. Using Netty with HTTP works fine. However, I cannot find any information how to configure Netty with TLS resp. HTTPS. Any hint is appreciated!
At the time of writing, configuration of TLS with Netty hasn't been implemented. The work is being tracked by this issue.
When multiple spring boot applications created and deployed to a tomcat server. Is it possible to use a common connection pooling, datasource instead of providing these details in application.properties file. Or does this already taken care within the spring boot implementation
When you deploy multiple application then each application manages it connection pool.
Spring boot boundary is limited to each application context and it does not know what other application deployed and which db they are using.
