Question

What is the advantage of using latching for concurrency control in adaptive indexing?

a.

Latching provides fine-grained control over data access.

b.

Latching is less efficient than full-fledged database locks.

c.

Latching is heavyweight and resource-intensive.

d.

Latching results in a lightweight concurrency control mechanism.

Posted under Big Data Computing

Answer: (d).Latching results in a lightweight concurrency control mechanism. Explanation:The advantage of using latching for concurrency control in adaptive indexing is that it results in a lightweight concurrency control mechanism. Latching is less resource-intensive compared to full-fledged database locks and is suitable for managing concurrent access to pieces of data during read queries in adaptive indexing.
