# Spring Webflux Benchmarking Test

This is the Spring Webflux portion of a [benchmarking test suite](../) comparing a variety of web development platforms.

Netty is used for the async web server, with nearly everything configured with default settings. The only thing changed is Hikari can use up to (2 * cores count) connections (the default is 10). See [About-Pool-Sizing](https://github.com/brettwooldridge/HikariCP/wiki/About-Pool-Sizing)

A fixed thread pool of size equals to the number of database connections is used to run all the blocking code (jdbc database accesses) to not block netty's event loop.

For postgresql access, there are four implementations.
* [JdbcDbRepository](src/main/java/benchmark/JdbcDbRepository.java) is using JdbcTemplate.
* [PgClientDbRepository](src/main/java/benchmark/PgClientDbRepository.java) is using reactive-pg-client
* [RxJava2DbRepository](src/main/java/benchmark/RxJava2DbRepository.java) is using rxjava2-jdbc
* [R2dbcDbRepository](src/main/java/benchmark/R2dbcDbRepository.java) is using r2dbc-postgresql
For mongoDB access, spring-data-mongodb with reactive support is used. See [MongoDbRepository](src/main/java/benchmark/MongoDbRepository.java)
