# Beta and experimental features

StarRocks features have five potential maturity levels:

* Experimental
* Beta
* Generally Available (GA)
* Deprecated
* Removed

Most of the StarRocks features are GA, and if there is no label in the documentation to indicate that a feature is Experimental, Beta, or Deprecated—then the feature is GA.

## Experimental features[​](#experimental-features "Direct link to Experimental features")

* **Stability**: Possibly buggy, with minor known issues.
* **Maturity**: Low
* **Interface**: The interface may be changed in the future. This includes command syntax, configuration parameters, defaults, feature removal, etc.
* **Availability**: Experimental features are off by default, and need to be allowed by setting a parameter with SQL or in a configuration file.
* **Production readiness**: Experimental features should not be used in production.
* **Support**: Please open a [GitHub issue](https://github.com/StarRocks/starrocks/issues) or ask questions in [Slack](https://docs.starrocks.io/join/) and the StarRocks Engineering team will try to help you.

## Beta features[​](#beta-features "Direct link to Beta features")

* **Stability**: Well tested. May be not good for corner cases.
* **Maturity**: Core functionality is complete, may not be performance-optimized.
* **Interface**: The interface may be changed in the future. May be not backward compatible.
* **Availability**: Beta features are off by default, and need to be allowed by setting a parameter with SQL or in a configuration file.
* **Production readiness**: Beta features are not recommended for production use.
* **Support**: Please open a [GitHub issue](https://github.com/StarRocks/starrocks/issues) or ask questions in [Slack](https://docs.starrocks.io/join/) and the StarRocks Engineering team will try to help you.

## GA features[​](#ga-features "Direct link to GA features")

* **Stability**: Comprehensively tested.
* **Maturity**: High.
* **Interface**: Stable API.
* **Availability**: GA features are on by default.
* **Production readiness**: Production ready.
* **Support**: The support team provides support to customers. Open-source community members should open a [GitHub issue](https://github.com/StarRocks/starrocks/issues) or ask questions in [Slack](https://docs.starrocks.io/join/) and the StarRocks Engineering team will try to help you.

## Deprecated features[​](#deprecated-features "Direct link to Deprecated features")

Some features are deprecated—marked for removal, because they are replaced with other features or the features were not being used. Generally when a feature is deprecated we will suggest an alternative in the documentation.
