SSI is the default isolation; clients must consciously decide to trade correctness for performance. The non-locking distributed commit protocol is still a work in progress but Kimball references papers from The University of Sidney, Yale, and draws special attention to a paper from Yahoo! as ...
SSI eliminates write skew, but introduces a performance hit in the case of a contentious system. SSI is the default isolation; clients must consciously decide to trade correctness for performance. CockroachDB implements a limited form of linearalizability, providing ordering for any observer or chain...

CockroachDB is a distributed SQL database built on a transactional and strongly-consistent key-value store. Itscaleshorizontally;survivesdisk, machine, rack, and even datacenter failures with minimal latency disruption and no manual intervention; supportsstrongly-consistentACID transactions; and provides a...

A database management system (DBMS) for servicing query statements through one or more client machines. The DBMS comprises a query interface adapted to receive query statements from the client machines. The query handling mechanism (i) receives each request from the query interface, (ii) extracts...
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...
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 ...
