Since its initial discussion in 2016, CockroachDB has enhanced its time-travel query feature by allowing users to specify relative times, making it easier to retrieve data as it appeared at a specific historical moment. This feature, compliant with the SQL:2011 standard and seen in other databases like Oracle and MSSQL, is particularly useful for tasks such as backups, undo operations, and historical reporting. Time-travel queries in CockroachDB work by modifying a request's timestamp to a desired historical point, supported by the database's Multi-Version Concurrency Control (MVCC) layer, which retains necessary data within a configurable garbage collection threshold. While these queries cannot currently be used in SQL transactions or subqueries, they facilitate efficient, lockless backups by allowing operations to proceed without being aborted. CockroachDB continues to refine this feature, aiming to enhance backup speeds and explore broader applications, while also addressing technical challenges such as schema changes and type-checking constraints.
