Providing isolation between record stores is key for multi-tenancy. On the data level, the keys of each record store start with a unique binary prefix which defines a FoundationDB subspace. FoundationDB Record

If the AccessIntent parameter is null, a default value is returned that is appropriate for the database backend. The default transaction isolation level for DB2DataStoreHelper is Connection.TRANSACTION_REPEATABLE_READ. In the case where an AccessIntent is specified...
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 of observers....
Cockroach provides snapshot isolation (SI) and serializable snapshot isolation (SSI) semantics … 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 ...

In terms of conflict detection, this provides the phantom protection that is needed to support serializable isolation in the presence of value-based retrieval operations. It also allows a transaction's readset dependency to be expressed efficiently, with arbitrary granularity. For example, a transaction...
