Exonum MerkleDB
MerkleDB is a document-oriented persistent storage which provides APIs to work with merkelized data structures. Under the hood, MerkleDB uses RocksDB as a key-value storage.
Features
- Supports list, map and set collections (aka indexes), as well as singular elements. Further, indexes can be organized into groups, allowing to create hierarchies of documents with arbitrary nesting.
- Automated state aggregation of top-level indexes into a single state hash, which reflects the entire database state.
- Ability to define data layouts in an intuitive, declarative format.
- Basic support of transactions: changes to the storage can be aggregated into a fork and then merged to the database atomically.
- Access control leveraging the Rust type system, allowing to precisely define access privileges for different actors.
- First-class support of long-running, fault-tolerant data migrations running concurrently with other I/O to the storage.
