0.1.0

clio is an XRP Ledger API server. clio is optimized for RPC calls, over websocket or JSON-RPC. Validated historical ledger and transaction data is stored in a more space efficient format, using up to 4 times less space than rippled.

clio uses Cassandra or ScyllaDB, allowing for scalable read throughput. Multiple clio nodes can share access to the same dataset, allowing for a highly available cluster of clio nodes, without the need for redundant data storage or computation.

0.1.0 is the first beta of Project Clio. It contains:

• ./src/backend is the BackendInterface. This provides an abstraction for reading and writing information to a database.
• ./src/etl is the ReportingETL. The classes in this folder are used to extract information from the P2P network and write it to a database, either locally or over the network.
• ./src/rpc contains RPC handlers that are called by clients. These handlers should expose the same API as rippled.
• ./src/subscriptions contains the SubscriptionManager. This manages publishing to clients subscribing to streams or accounts.
• ./src/webserver contains a flex server that handles both http/s and ws/s traffic on a single port.
• ./unittests simple unit tests that write to and read from a database to verify that the ETL works.
