Possible disadvantages of Realm.io

  • Storage Size
    Realm databases can become large quickly, especially if not properly managed, potentially impacting app performance and storage costs.
  • Limited Query Language
    While powerful, Realm's query language isn't as mature or feature-rich as SQL, which might limit some advanced querying needs.
  • Tooling
    The tooling ecosystem for Realm is not as extensive as those for more established databases like SQLite or MongoDB, which could impact developer productivity.
  • Vendor Lock-In
    Using Realm might lead to vendor lock-in, as migrating away from it to another database system can be complex and time-consuming.
