Moreover, we have a multiple granularity lock model [4] > where some lock modes are compatible, others are not, which allows > reenterability in some cases, and sharing of locks between transactions. We > should understand the differences of behavior of each implementation in > different scenarios, and how it matches with our expectations. > *Definition of done* > Table with a set of scenarios and description of behavior, including the > expected one. > [1] org.apache.ignite.internal.tx.impl.HeapLockManager > [2] https://github.com/ascherbakoff/ai3-txn-mvp > [3] https://dl.acm.org/doi/pdf/10.1145/320251.320260 > [4] https://web.stanford.edu/class/cs245/readings/granularity-of-locks.pdf -- This message was sent by Atlassian Jira (v8.20.10#820010)
