 * **Easy to learn:** RisingWave speaks PostgreSQL-style SQL, enabling users to dive into stream processing in much the same way as operating a PostgreSQL database.
 * **Highly efficient in multi-stream joins:** RisingWave has made significant optimizations for multiple stream join scenarios. Users can easily join 10-20 streams (or more) efficiently in a production environment.
 * **High resource utilization:** Queries within RisingWave benefit from shared computational resources, obviating the need for users to manually allocate resources for individual queries.
-* **No compromise on large state management:**: The decoupled compute-storage architecture of RisingWave ensures remote persistence of internal states, and users never need to worry about the size of internal states when handling complex queries.
+* **No compromise on large state management:** The decoupled compute-storage architecture of RisingWave ensures remote persistence of internal states, and users never need to worry about the size of internal states when handling complex queries.
 * **Transparent dynamic scaling:** RisingWave supports near-instantaneous dynamic scaling without any service interruptions.
 * **Instant failure recovery:** RisingWave's state management mechanism allows it to recover from failure in seconds, not minutes or hours.
 * **Easy to verify correctness:** RisingWave persists results in materialized views and allow users to break down complex stream computation programs into stacked materialized views, simplifying program development and result verification.
 * **Simplified data stack:** RisingWave's ability to store data and serve queries eliminates the need for separate maintenance of stream processors and databases. Users can effortlessly link RisingWave to their preferred BI tools or through client libraries.
-* **Simple to maintain and operate:** -   RisingWave abstracts away unnecessary low-level details, allowing users to concentrate solely on SQL code-level issues.
