Abstract
Technologies are described for facilitating the processing of requests for database operations in a distributed database environment. Criteria are defined for processing a request for a database operation according to first or second snapshot isolation protocols. A request for a database operation is received and it is determined if the snapshot isolation protocol criteria are met. If the criteria are met, the request can be processed using a local snapshot identifier value of a worker node. If the criteria are not met, the local snapshot identifier value is synchronized with another node, and the request processed using the updated snapshot identifier value.
