Cosmos DB Interview Questions and Answers
Question - 51 : - Does Azure Cosmos Db Table Api Offer More Consistency Levels Than Azure Table Storage?
Answer - 51 : - Yes, for information approximately how to benefit from the allotted nature of Azure Cosmos DB, see Consistency levels. Because ensures are provided for the consistency degrees, you can use them with confidence.
Question - 52 : - When Global Distribution Is Enabled, How Long Does It Take To Replicate The Data?
Answer - 52 : - Azure Cosmos DB commits the statistics durably within the neighborhood area and pushes the data to different regions right away in a be counted of milliseconds. This replication is dependent handiest at the spherical-experience time (RTT) of the datacenter.
Question - 53 : - Can The Read Request Consistency Level Be Changed?
Answer - 53 : - With Azure Cosmos DB, you may set the consistency degree at the box degree (at the table). By the use of the .NET SDK, you could exchange the level by supplying the price for Table ConsistencyLevel key inside the app.Config document. The feasible values are: Strong, Bounded Staleness, Session, Consistent Prefix, and Eventual. For more records, see Tunable statistics consistency tiers in Azure Cosmos DB. The key concept is which you can not set the request consistency degree at extra than the placing for the table. For example, you can not set the consistency level for the table at Eventual and the request consistency degree at Strong.
Question - 54 : - How Does The Table Api Handle Failover If A Region Goes Down?
Answer - 54 : - The Table API leverages the globally distributed platform of Azure Cosmos DB. To make sure that your software can tolerate datacenter downtime, enable as a minimum one greater region for the account within the Azure Cosmos DB portal Developing with multi-place Azure Cosmos DB debts. You can set the priority of the location through using the portal growing with multi-place Azure Cosmos DB bills.
You can add as many areas as you need for the account and control where it could fail over to via offering a failover precedence. Of direction, to apply the database, you want to provide an utility there too. When you accomplish that, your clients will now not revel in downtime. The modern day .NET consumer SDK is automobile homing however the other SDKs are not. That is, it is able to detect the region that's down and robotically fail over to the brand new place.
Question - 55 : - Is The Table Api Enabled For Backups?
Answer - 55 : - Yes, the Table API leverages the platform of Azure Cosmos DB for backups. Backups are made mechanically.
Question - 56 : - Does The Table Api Index All Attributes Of An Entity By Default?
Answer - 56 : - Yes, all attributes of an entity are indexed by using default.
Question - 57 : - Does This Mean I Do Not Have To Create Multiple Indexes To Satisfy The Queries?
Answer - 57 : - Yes, Azure Cosmos DB Table API presents computerized indexing of all attributes without any schema definition. This automation frees developers to attention at the software instead of on index creation and control.
Question - 58 : - Azure Cosmos Db As A Platform Seems To Have Lot Of Capabilities, Such As Sorting, Aggregates, Hierarchy, And Other Functionality. Will You Be Adding These Capabilities To The Table Api?
Answer - 58 : - The Table API affords the equal query functionality as Azure Table garage. Azure Cosmos DB also helps sorting, aggregates, geospatial query, hierarchy, and a huge variety of integrated features. We will offer extra capability inside the Table API in a future service replace.
Question - 59 : - When Should I Change Table Throughput For The Table Api?
Answer - 59 : - You ought to trade Table Throughput whilst either of the following conditions applies:
You're performing an extract, transform, and load (ETL) of information, or you want to upload a number of statistics in brief amount of time.
You want more throughput from the field on the returned cease. For instance, you notice that the used throughput is greater than the provisioned throughput, and you have become throttled.
Question - 60 : - Can I Scale Up Or Scale Down The Throughput Of My Table Api Table?
Answer - 60 : - Yes, you may use the Azure Cosmos DB portal’s scale pane to scale the throughput.
