The is called the <em>transaction log</em>.</li> + <li>When the system goes down (intentionally or unintentionally) we restore its latest state by first reading in the latest snapshot and by re-executing each transaction from the transaction log.</li> + <li>Transactions must be deterministic and re-entrant (so they also need to record the current time if necessary).</li> + <li>In a multi-threaded system, transactions are globally serialized.</li> +</ul> +<p> +That is all there is to the concept of object prevalence. Here are some more details as well as some advantages and limitations: +</p> +<ul> + <li>A good implementation on a modern machine can achieve thousands of transactions per second, and recover them at about the same speed.</li> + <li>Transactions must be short because they block the system - since everything is in RAM this is not a problem.</li> + <li>Queries that need to see a completely consistent system state must also block on the system - other less critical queries could run in parallel.</li> + <li>It is practical for a transaction to first check its preconditions, throw an error if necessary, and to only modify the system when everything is consistent. During a transaction you are the sole active thread. Queries are as fast as they can get. In this implementation transactions are logged after succesful execution.</li> + <li>In this implementation there is an option to do a rollback (by doing a system restore) when an unexpected error occurs during transaction execution. You can specifiy that a condition doesn't need a rollback when it occurs inside a transaction by implementing the <tt>initiates-rollback</tt> to return false (or by using the <tt>no-rollback-error</tt> condition or inheriting from it).</li> + <li>Long running transactions are an open question.</li> + <li>Application server techniques are used to offer multiple clients access to the same prevalence system.</li> + <li>We can easily do replication (and query load balancing) by distributing the master transaction log stream to replica's that can host queries, execute backups (snapshots) or serve as hot fail-over.
