  • Q3. Is Redis single-threaded or multi-threaded?
  • Ans. 

    Redis is single-threaded.

    • Redis is single-threaded, meaning it can only execute one command at a time.

    • This design choice allows Redis to be extremely fast and efficient for certain use cases.

    • However, it also means that Redis may not be the best choice for highly concurrent workloads.

  • Q4. What sort of data types can be used as keys in Python?
  • Ans. 

    Data types that can be used as keys in Python include strings, integers, floats, tuples, and custom objects.

    • Strings are commonly used as keys in Python dictionaries.

    • Integers and floats can also be used as keys.

    • Tuples can be used as keys if they only contain immutable elements.

    • Custom objects can be used as keys if they are hashable.

    • Examples: {'name': 'John'}, {1: 'apple'}, {(1, 2): 'tuple'}

  • Answered by AI
  • Q5. What types of indexing exist in SQL?
  • Ans. 

    Types of indexing in SQL include clustered, non-clustered, unique, and composite indexes.

    • Clustered index physically reorders the table based on the index key

    • Non-clustered index creates a separate structure for the index

    • Unique index ensures that all values in the index column are unique

    • Composite index uses multiple columns for indexing
