The subject technology receives a first transaction. The subject technology allocates a first read version to a first transaction, the first read version indicating a first version that can be linearized stored. The subject technology performs a read operation from a first transaction on a table in a database. The subject technology determines a first submitted version identifier corresponding to first data generated by a read operation. In response to determining that there is no particular write operation in the first transaction, the subject technology continues to execute a different transaction and abandons execution of a commit process associated with the first transaction. 主题技术接收第一事务。主题技术将第一读取版本分配给第一事务，第一读取版本指示可线性化存储的第一版本。主题技术对数据库中的表执行来自第一事务的读取操作。主题技术确定对应于由读取操作产生的第一数据的第一提交版本标识符。响应于确定第一事务中不存在特定写入操作，主题技术继续执行不同的事务，并放弃执行与第一事务相关的提交过程。
