+[Delta Lake](https://delta.io/) is an open-source cloud storage layer for data lakes with [ACID transactions](OptimisticTransaction.md), [time travel](time-travel/index.md) and [many more](features/index.md) (you'd rather not wanna miss in your data-heavy architectures).
 
-As [it was well said](https://github.com/delta-io/delta/issues/467#issuecomment-696708455): _"Delta is a storage format while Spark is an execution engine...to separate storage from compute."_
+As [it was well said](https://github.com/delta-io/delta/issues/467#issuecomment-696708455): _"Delta is a storage format while Spark is an execution engine...to separate storage from compute."_ Yet, Delta Lake can run with other execution engines like [Trino](https://trino.io/docs/current/connector/delta-lake.html) or [Apache Flink](https://github.com/delta-io/connectors/tree/master/flink).
 
 Delta Lake {{ delta.version }} supports Apache Spark {{ spark.version }} (cf. [build.sbt]({{ delta.github }}/build.sbt#L19)).
