What is a potential downside of using a single partition key for all data in a Cassandra table?

Creation of a hotspot

Reduced data redundancy

Improved query performance

Increased consistency level requirements

None

Using a single partition key for all data can create a hotspot, as all data will be stored on a single node, leading to uneven load distribution and potential performance bottlenecks.

Which strategy is recommended for token allocation in a Cassandra cluster with varying node capacities?

Use virtual nodes (vnodes)

Assign equal tokens to all nodes

Manually assign tokens based on node capacity

Use a single token per node

None

Using virtual nodes (vnodes) is recommended in clusters with varying node capacities because it allows for automatic and even distribution of data, accommodating nodes of different sizes without manual intervention.
