    2929All queries accessing the database will go through our interface, which intercepts and interprets the queries. This will allow us to put the entire system in special mode (user queries will be queued, administrative queries will continue to work). The administrative tools we are building will allow us to push the necessary updates to all nodes, and we could use the existing scheduling mechanisms to run the upgrade in the most efficient fashion. The admin tools will also allow to run necessary verifications (eg. whether the schema for all table chunks matches).
