How long will keyed state exist if no TTL given?

[Marco Villalobos-2]

After reading

https://ci.apache.org/projects/flink/flink-docs-release-1.11/dev/stream/state/state.html

It is unclear to me how long keyed state will exist if it has no TTL.
Is it cached forever, unless explicitly cleared or overwritten?

can somebody please explain to me?

Thank you.
