A shared log system can provide a key-index structure (main map) that allows clients (users) to access the state of objects stored in the shared log system. The client can define secondary indices on the main map to provide access to the data that are tailored to the client's data needs. Each client can generate their own customized set of secondary indices different from other clients.

Just-in-time multi-indexed tables in a shared log

A shared log in a distributed system provides for direct access to the most current data state of an object stored in the shared log. Directly accessing the data state of an object obviates the need for a client to replay all the transactions stored in the shared log made on the object.

Direct access to object state in a shared log

In accordance with disclosed embodiments, a shared log system includes a sequencer to verify transactions that comprise a source object and one or more members of the source object (source data objects), a target object and one or more members of the target object (target data objects), and a snapshot time reference. The sequencer verifies transaction using the snapshot time to determine whether the data states of the source data objects at the time of the snapshot time represent their most current data state in a shared log.
