Microsoft Azure Data FundamentalsDescribe how to work with non-relational data on AzureHard
A global online gaming platform uses Azure Cosmos DB to store player profiles, game statistics, and leaderboards. To ensure the best possible performance and lowest latency for players worldwide, the platform needs to allow data writes from any region where players are active. Which Azure Cosmos DB feature enables this capability?
- AAutomatic Failover
- BStrong Consistency
- CMulti-region writes
- DChange Feed
Show answer & explanationAnswer & explanation
Correct answer: C. Multi-region writes
Multi-region writes in Azure Cosmos DB allow applications to write data to any configured region, ensuring low-latency writes for globally distributed users. This is crucial for a gaming platform where players are active worldwide and need responsive interactions regardless of their location.
Why the other options are wrong
- A. Automatic Failover ensures high availability during regional outages, but doesn't enable writing from all regions simultaneously.
- B. Strong Consistency defines how data updates are synchronized, not where writes can originate from globally.
- D. Change Feed provides a continuous stream of new data, useful for integration, but doesn't enable global write capabilities.
Azure Cosmos DB Multi-region Writes
A feature in Azure Cosmos DB that allows applications to write data to any configured region in a globally distributed database, ensuring low-latency writes for users worldwide.
- Enables global low-latency writes
- Data can be written from any region
- Crucial for globally distributed applications
- Requires specific configuration in Cosmos DB
Memory trick: Global gaming needs 'multi-region writes' to thrill players everywhere.
