It is a premium storage service that Azure provides for a globally distributed, low
latency, highly responsive, and always online Database. Has scalability and
throughput in mind. - CORRECT ANSWER-What is Cosmos DB
Key-Value
Column Family
Documents
Graph Approaches - CORRECT ANSWER-What are the 4 ways you can store your
data in Cosmos DB?
SQL, Cassandra, Table, Gremlin, and MongoDB - CORRECT ANSWER-What are
the current APIs that can access CosmosDB?
It is the core and default API for accessing data in CosmosDB. You can query JSON
objects using SQL syntax, Uses Javascript. This is a Data Structure based on
Documents. - CORRECT ANSWER-What is SQL API?
,It is like the evolution of Azure Table Storage. It has High Performance, low
latency, and highly scalable features. Can migrate from Azure table storage with
no code modifications. You can define your own indexes. This is a data structure
based on Documents. - CORRECT ANSWER-What is Table API
This is a wire protocol Apache Data Base. How this is implemented means you do
not have to worry about operations or performance management tasks related to
managing this DB. Can migrate from a Cassandra DB to this DB merely by
changing the connection string. Compatible with CQLv4 wire protocol. This is a
Column Based DB that stores info in a Key-Value approach. - CORRECT
ANSWER-What is Cassandra API?
This is a NoSQL DB with a Document based Structure. CosmosDB enables a wire
protocol to connect but this API must be version 3.2 or higher. - CORRECT
ANSWER-What is MongoDB API?
Based on Apache TinkerPop Graph transversal language. This uses a Graph
structure. This stores entities but also:
1. Vertices - (entity such as person, device or event)
2. Edges - Relationships between vertices
3. Properties - each of the attributes that are assigned to a vertex or edge. -
CORRECT ANSWER-What is Gremlin API?
, No you can only choose one. - CORRECT ANSWER-Can you use multiple APIs in a
single CosmosDB account?
When you divide a CosmosDB container into smaller pieces, each piece is a logical
partition. All items stored on this partition share the same partition key. -
CORRECT ANSWER-What is a logical partition for Cosmos DB
A group of replicas of data that is physically stored on servers. Azure manages this
group of replicas. Can contain one or more Logical partitions. - CORRECT
ANSWER-What is a physical partition for CosmosDB?
20GB - CORRECT ANSWER-By default what is the storage limit for a logical
partition?
It is when you select a partition key with few possible values and the partition
receives most of the requests reaching the throughput limit. - CORRECT
ANSWER-What is a "hot" partition?
100 request units per second (R/Us) - CORRECT ANSWER-What is the min
throughput for DB's
400 request units per second (R/Us) - CORRECT ANSWER-What is the min
throughput for Containers?
