-## RisingWave's limitations
-RisingWave isn’t a panacea for all data engineering hurdles. It has its own set of limitations:
-* **No programmable interfaces**
-  * RisingWave does not provide low-level APIs in languages like Java and Scala, and does not allow users to manage internal states manually (unless you want to hack!). _For coding in Java, Python, and other languages, please consider using RisingWave's [User-Defined Functions (UDF)](https://docs.risingwave.com/docs/current/user-defined-functions/)_.
-* **No support for transaction processing**
-  * RisingWave isn’t cut out for transactional workloads, thus it’s not a viable substitute for operational databases dedicated to transaction processing. _However, it supports [read-only transactions](https://docs.risingwave.com/docs/current/transactions/#read-only-transactions), ensuring data freshness and consistency. It also comprehends the transactional semantics of upstream database [Change Data Capture (CDC)](https://docs.risingwave.com/docs/current/transactions/#transactions-within-a-cdc-table)_.

-## In-production use cases
-Like other stream processing systems, the primary use cases of RisingWave include monitoring, alerting, real-time dashboard reporting, streaming ETL (Extract, Transform, Load), machine learning feature engineering, and more. It has already been adopted in fields such as financial trading, manufacturing, new media, logistics, gaming, and more. Check out [customer stories](https://www.risingwave.com/use-cases/).
