Property-Value Storage Engine

Property-Value Store (Cloud Storage)

At a high-level, a property-value store uses:

  • Keys - Object keys are <Object UUID> and BLOB value keys are <Object UUID>:<Field UUID>
  • Values - Objects are stored as cJSON. BLOB values are stored as UTF-8 text or binary data.

The details still need to be figured out. Is it just for storage of objects and BLOB/CLOB values, and a database (SQLite at a minimum) will be required to store and index objects and non-BLOB/CLOB values.


  • Is the index required, or can it be rebuilt by "crawling" the object store?
  • How are queries performed efficiently?
  • Are recently/frequently accessed BLOB/CLOB values cached locally in some way?
