Otherwise, a non-locking distributed commit protocol is employed between affected ranges. Cockroach provides snapshot isolation (SI) and serializable snapshot isolation (SSI) semantics, allowing externally consistent, lock-free reads and writes--both from an historical snapshot timestamp and from the...

isolation and time travel, and because the fully persistent trees are suitable for append-only storage such as flash memory. Moreover, since fully persistent trees are immutable, cached copies are consistent. Thus, fully persistent trees are useful in distributed systems and large shared-memory ...

In an embodiment, data sets stored at off-premise environment104that correspond to different tenants are isolated from each other. As illustrated in FIG. 1A, data set132corresponds to tenant112, and data set134corresponds to tenant114. Tenant isolation may be achieved using, for example, tenant...
