-### Further Work:
+### [Limitations](#limitations)
+
+1) The emulator works well in development and test environments, but does not have the [strict](https://ambar.cloud/blog/provably-correct-data-streaming-our-white-paper) delivery and durability guarantees required of production environments.
+2) The emulator consumes more resources on databases and web servers, because it does not implement features such as change data capture and [adaptive load](https://ambar.cloud/blog/optimal-consumption-with-adaptive-load).
+3) The emulator can handle thousands of messages per second but does not scale horizontally, because the emulator can only run in a single machine.
+4) The emulator doesn't provide filtering (yet - we will eventually add this).
+
+### Upcoming Features:
 
 - [ ] Add support for MySQL
 - [ ] Add support for MariaDB
 - [ ] Add support for SQL Server
+- [ ] Add support for filtering
 - [ ] Add support for Oracle
 - [ ] Add support for MongoDB
-- [ ] Add support for filtering capabilities
