# Data Synchronization ```{page-status} draft created to drop thoughts on limitations (2026/04) ``` # Limitations The following limitations should be reviewed and updated after feature creation and potentially added to the user space documentation. The limitations represent a draft and numbers are very variable. **Data exchange** with other instances is based on one or a few (like 3) people having writing rights while more (like 50) are just consuming the results. * See security feature: you essentially give away your email or database passwords to the people with writing rights. * **Update frequency** is expected to be around 20 times a week, and rare (once a month) peak reads are around 150 times/h. * Methods provided to exchange data are not suited for continuous data exchange between instances.
