When manually stopping a Flink job through Apache StreamPark, users have the option to perform a savepoint. If this option is selected, the path of the savepoint is saved in the database. In addition, records of each checkpoint are also stored in the database. When restarting a Flink job, the system defaults to using the latest checkpoint or savepoint record. This effectively prevents issues associated with failing to recover from the previous checkpoint. It also avoids the resource wastage caused by having to rerun jobs with offset rollbacks to address problems, while ensuring consistency in data processing. +Another issue that Apache StreamPark™ resolves is safeguarding Flink's state recovery.

In a corporate setting, there are typically multiple environments, such as development, testing, and production. Each environment generally includes multiple components, such as Kafka, HBase, Redis, etc. Additionally, within a single environment, there may be multiple instances of the same component. For example, in a real-time computing platform at China Union, when consuming data from an upstream Kafka cluster and writing the relevant data to a downstream Kafka cluster, two sets of Kafka are involved within the same environment. It can be challenging to determine the specific environment and component based solely on IP addresses. To address this, we define the IP addresses of all components as variables. For instance, the Kafka cluster variable, Kafka.cluster, exists in development, testing, and production environments, but it points to different Broker addresses in each. Thus, regardless of the environment in which a Flink job is configured, referencing this variable is sufficient. This approach significantly reduces the incidence of operational failures in production environments. +Apache StreamPark™ also addresses the challenges associated with referencing multiple components across various environments.

If the Flink UID is not set, it could lead to situations where state recovery is not possible when upgrading the Flink job. This issue cannot be solved through the platform at the moment. Therefore, we plan to add this functionality to the platform. We will introduce a feature that checks whether the operator has a UID set when submitting a Flink Jar. If not, a reminder will be issued to avoid state recovery issues every time a Flink job is deployed. Previously, when facing such situations, we had to use the state processing API to deserialize from the original state, and then create a new state using the state processing API for the upgraded Flink to load. -- More Detailed Monitoring: Currently, Apache StreamPark supports sending alerts when a Flink job fails.

+`Apache StreamPark™` is an easy-to-use stream processing application development framework and one-stop stream processing operation platform, Aimed at ease building and managing streaming applications, Apache StreamPark™ provides scaffolding for writing streaming process logics with Apache Flink and Apache Spark.
+Apache StreamPark™ also provides a professional task management including task development, scheduling, interactive query, deployment, operation, maintenance, etc.
## Why Apache StreamPark™
Apache Flink and Apache Spark are widely used as the next generation of big data streaming computing engines. Based on a bench of excellent experiences combined with best practices, we extracted the task deployment and runtime parameters into the configuration files. In this way, an easy-to-use RuntimeContext with out-of-the-box connectors would bring easier and more efficient task development experience. It reduces the learning cost and development barriers, hence developers can focus on the business logic.
-On the other hand, It can be challenge for enterprises to use Flink & Spark if there is no professional management platform for Flink & Spark tasks during the deployment phase. Apache StreamPark provides such a professional task management platform, including task development, scheduling, interactive query, deployment, operation, maintenance, etc.
