In certain cases, it is less expensive to avoid a deadlock than it is to resolve one after it has already happened.

CSC 472 Introduction to Database Systems Project Consider the hashing approach for computing aggregations. If the size of the hash table is too large to fit in memory, then the DBMS has to spill it to disk. During the Partition phase, a hash function h1 is used to split tuples into partitions on disk based on targethash key. During the ReHash phase, the DBMS can store pairs of the form (GroupByKey -> RunningValue) to computethe aggregation. Which of the following is FALSE ? Group of answer choices The Partition phase will put all tuples that match (using h1) into the same partition. To insert a new tuple into the hash table, a new (GroupByKey -> RunningValue) pair is inserted if it finds a matching GroupByKey. A second hash function (e.g., h2) is used in the ReHash phase. The RunningValue could be updated during the ReHash phase.

Deadlock only happens when mutual exclusion, hold-and-wait, no preemption and circular wait are present. Define"circular wait" and explain how it contributes, potentially, to deadlock.
