instrumentation for the Reactor Framework (https://projectreactor.io/)\n  \n## Transaction Views   \nThis instrumentation provides two different ways to view transaction in an application using Reactor.  Releaase V2.0 provides a Distributed Tracing view where a request will generate multiple transactions that are tied together in the Distributed Tracing View of the New Relic Java Agent UI.  Release V1.1 uses the New Relic Java Agent Async token to tie things together into a single transaction showing actions across all threads.   \n### Pros and Cons   \nThe pro of using V1.1 is that it results in a single transaction in both the Transaction Trace view and the Distributed Tracing view.   The con is that in a high throughput environment where Reactor actions happen across multiple threads it can lead to high memory usage for the async token cache.   \nThe pro of using v2.0.0 (\u0026 onwards) is that it has a much lower memory usage.  The con is that to view what happens with the request you can only use the Distributed Tracing view.   \n\n## Installation\n   \nTo install:\n\n1. Download the latest release jar files.\n2. In the New Relic Java directory (the one containing newrelic.jar), create a directory named extensions if it does not already exist.\n3. Copy the downloaded jars into the extensions directory.\n4. Restart the application.\n## Getting Started\n\nOnce installed the instrumentation will track when a Mono or Flux object is placed on a scheduler for either the subscribe or the observe (or both).  The reactor finder extension instruments methods which return a Mono or a Flux object except these classes in the Reactor framework.\n   \n## Building\n\nBuilding the extension requires that Gradle is installed.\nTo build the extension jars from source, follow these steps:\n### Build single extension\nTo build a single extension with name *extension*, do the following:\n1. Set an environment variable *NEW_RELIC_EXTENSIONS_DIR* and set its value to the directory where you want the jar file built.\n2. Run the command: gradlew *extension*:clean *extension*:install\n### Build all extensions\nTo build all extensions, do the following:\n1. Set an environment variable *NEW_RELIC_EXTENSIONS_DIR* and set its value to the directory where you want the jar file built.\n2. Run the command: gradlew clean install\n\n## Testing\n\n\u003e[**Optional** - Include instructions on how to run tests if we include tests with the codebase.
