### Make a change in the build

There are a few guidelines to follow that should make your life easier to make changes to the elasticsearch build.
Please add a member of the `es-delivery` team as a reviewer if you're making non-trivial changes to the build.

#### Custom Plugin and Task implementations

Build logic that is used across multiple subprojects should considered to be moved into a Gradle plugin with according Gradle task implmentation.

	return err.Error() == "sql: statement is closed"
}

// TestPreparedStmtConcurrentClose test calling close and executing SQL concurrently
// this test making sure that the gorm would not get a Segmentation Fault, and the only error cause by this is using a closed Stmt
func TestPreparedStmtConcurrentClose(t *testing.T) {
	name := "prepared_stmt_concurrent_close"

* Systemd
* Supervisor
* Handled internally by a cloud provider as part of their services
* Others...

I'll give you more concrete examples in the next chapters.

## Restarts { #restarts }

Similar to making sure your application is run on startup, you probably also want to make sure it is **restarted** after failures.

Events
======

Events allow you to capture metrics on your application’s HTTP calls. Use events to monitor:

 * The size and frequency of the HTTP calls your application makes. If you’re making too many calls, or your calls are too large, you should know about it!
 * The performance of these calls on the underlying network. If the network’s performance isn’t sufficient, you need to either improve the network or use less of it.
