Exam DP-201 topic 2 question 2 discussion

Speed layer: Cosmos DB, Long-term store: Synapse

Speed layer: Cosmos , Long-term : Synapse

Cosmos DB + ASA fit appropriately for this question I think.

The kappa architecture was proposed by Jay Kreps as an alternative to the lambda architecture. It has the same basic goals as the lambda architecture, but with an important distinction: All data flows through a single path, using a stream processing system ,Analytical data store Azure Synapse Analytics, Azure Data Explorer, HBase, Spark, or Hive. Processed real-time data can be stored in a relational database such Synapse Analytics, Azure Data Explorer, a NoSQL store such as HBase, or as files in distributed storage over which Spark or Hive tables can be defined and queried. https://docs.microsoft.com/en-us/azure/architecture/data-guide/big-data/real-time-processing

speed layer should be Cosmos DB, based on following article. Long term is correct. Data stored in Parquets. https://azure.microsoft.com/en-us/blog/lambda-architecture-using-azure-cosmosdb-faster-performance-low-tco-low-devops/

There must be a reason why you said that

i don't think this's the right answer
