Vladislav Pyatkov updated IGNITE-18043:
---------------------------------------
Description:
We have an embedded deadlock prevention strategy (presently, it is _Wait-Die_).
Although, [the original
paper|https://people.eecs.berkeley.edu/~brewer/cs262/concurrency-distributed-databases.pdf]
about deadlock prevention contains another two strategies: _priorities_ and
_Wound-Wait_. Also, the mechanism should give a possibility to not use any
strategy to prevent deadlock.
All told, above shows we need to separate the prevention strategy in dedicate
interface (which even has one implementation _Wait-Die_). Another
implementation will be released by necessary.
