Synapse / Data Factory: Do Self Hosted Integration Runtimes expose data locally

Question

We need to ensure that the VM hosting the Self Hosted Integration Runtime (SHIR) can be supported without risking exposure of the data being processed by the SHIR - which may be sensitive in nature.

What information related to data sources is cached locally on the VM hosting a Self Hosted Integration Runtime (SHIR)? For example, if SHIR is pulling data from an on-prem SQL Server, is it possible that data queried could be exposed in error / event logs on the VM?

Thanks.

According to the documentation, this is not a risk

Azure Data Factory including Azure Integration Runtime and Self-hosted Integration Runtime does not store any temporary data, cache data or logs except for linked service credentials for cloud data stores, which are encrypted by using certificates.
