Ques. 3): In Amazon Neptune, what are IOs and how are they calculated?

To cut expenses and make sure resources are available for serving read/write traffic, Amazon Neptune was built to do away with pointless IO activities. Only when pushing transaction log records to the storage layer in order to make writes persistent, write IOs are used. 4KB units are used to measure write IOs. One IO operation, for illustration, would be the 1024-byte transaction log record. However, in order to reduce I/O consumption, the Amazon Neptune database engine can batch together concurrent write operations whose transaction log is less than 4KB. Amazon Neptune doesn't push updated database pages to the storage layer like traditional database engines do, which reduces IO usage even further.

Ques. 6): How is the fault tolerance of my database to disc failures improved by Amazon Neptune?

Your database volume is automatically divided into 10GB parts and distributed over several discs by Amazon Neptune. Your database volume is replicated six times, over three availability zones, for each 10GB piece. Without compromising database write availability or read availability, Amazon Neptune is built to transparently withstand the loss of up to two copies of data at once. Additionally self-healing is Amazon Neptune storage. Disks and data blocks are automatically checked for faults on a constant basis.

Ques. 7): How can the availability of a single Amazon Neptune database be improved?

Amazon Neptune Replicas are an option. The primary instance and Amazon Neptune Replicas share the same underlying storage. To increase fault tolerance in the event of a primary DB Instance failure, any Amazon Neptune Replica can be promoted to become primary without causing any data loss. Simply add 1 to 15 replicas to your database to boost availability, and Amazon Neptune will automatically choose them for failover main selection in the event of a database failure.

AWS Elastic Block Store (EBS) Interview Questions and Answers

Ques. 8): How long does failover take? What happens during failover?

Amazon Neptune handles failover automatically so that your applications can resume database operations as soon as feasible without needing to call in a manual administrator.

When failing over, Amazon Neptune flips the canonical name record (CNAME) for your database's primary endpoint to a healthy replica, which is then promoted to become the new primary, if you have an Amazon Neptune Replica in the same or a different Availability Zone. Failover normally takes 30 seconds to complete from beginning to end. Additionally, during failover, the read replicas endpoint doesn't need any CNAME modifications.

Neptune will first try to establish a new DB Instance in the same Availability Zone as the original instance if you don't already have one (i.e., a single instance). Neptune will try to build a new DB Instance in a different Availability Zone if it is unable to do so. Failover normally takes less than 15 minutes to execute from beginning to end.

Ques. 10): Can I use RDF/SPARQL and Apache TinkerPop Gremlin on the same Neptune instance?

Yes, each Neptune instance offers both a SPARQL 1.1 Protocol REST endpoint and a Gremlin Websocket Server. Since the data is divided between the stacks, neither Gremlin nor RDF traversals are possible. This is meant to provide you the opportunity to try them out and evaluate which one works best for your application. Due to the shared nature of the resources on a single instance in production, Amazon advises clients to limit their access to an instance to either Gremlin or SPARQL.

AWS Aurora Interview Questions and Answers

Ques. 13): My photos can I share with another AWS account?

Yes. You can take database snapshots with Neptune that you can subsequently utilise to restore a database from. AWS accounts can be shared, and the owner of the receiving account can utilise the shared snapshot to restore a database that contains your data. Anybody can restore a database containing your (public) data if you decide to make your snapshots public. This functionality allows you to securely store backups of all your data in a second account in case your primary AWS account is ever compromised, communicate data between your multiple environments (production, dev/test, staging, etc.) that each have their own AWS accounts, and more.

AWS Database Interview Questions and Answers

AWS ActiveMQ Interview Questions and Answers

Ques. 14): How does Amazon Neptune speed up database recovery time?

Unlike other databases, Amazon Neptune does not need to replay the redo log from the most recent database checkpoint, which generally takes place after 5 minutes, to ensure that all changes have been made before rendering the database usable for operations following a database crash. In most cases, this cuts down database restart times to under 60 seconds. When the database process is restarted, Amazon Neptune removes the buffer cache and makes it immediately accessible. This saves you from having to restrict access while the cache is being refilled in order to prevent brownouts.

AWS CloudFormation Interview Questions and Answers

AWS GuardDuty Questions and Answers

Ques. 15): Is it possible to choose some replicas as failover targets before others?

Yes. Each instance in your cluster might have a different promotion priority tier assigned to it. Amazon Neptune will upgrade the replica with the highest priority to the primary instance if the primary instance fails. The replica that is the same size as the primary instance will be promoted if there is a tie between two or more replicas in the same priority tier.

AWS(Amazon Web Services) Interview Questions and Answers

AWS Cloud Interview Questions and Answers

Ques. 1): What performance can I expect from Amazon Timestream?

Answer:

Amazon Timestream offers near real-time latencies for data ingestion. Amazon Timestream’s built-in memory store is optimized for rapid point-in-time queries, and the magnetic store is optimized to support fast analytical queries. With Amazon Timestream, you can run queries that analyze tens of gigabytes of time-series data from the memory store within milliseconds, and analytical queries that analyze terabytes of time-series data from the magnetic store within seconds. Scheduled queries further improve query performance by calculating and storing the aggregates, rollups, and other real-time analytics used to power frequently accessed operational dashboards, business reports, applications, and device-monitoring systems.

As your applications continue to send more data, Amazon Timestream automatically scales to accommodate their data ingestion and query needs. You can store exabytes of data in a single table. As your data grows over time, Amazon Timestream uses its distributed architecture and massive amounts of parallelism to process larger and larger volumes of data while keeping query latencies almost unchanged.

AWS Cloud Practitioner Essentials Questions and Answers

AWS EC2 Interview Questions and Answers

Ques. 4): Can I use Amazon Timestream to automatically roll up, combine, or preprocess my data?

Answer:

For calculating and storing aggregates, rollups, and other real-time analytics required to power frequently viewed operational dashboards, business reports, applications, and device monitoring systems, Amazon Timestream's scheduled queries provide a fully managed, serverless, and scalable solution.

To calculate aggregates, rollups, and other real-time analytics on your incoming data, you just describe the real-time analytics queries with scheduled queries. Amazon Timestream then periodically and automatically runs these queries and reliably stores the query results into a different table. Your dashboards, reports, programmes, and monitoring tools can then be configured to just query the destination tables rather than the much larger source tables that hold the incoming time-series data. This leads to performance and cost reductions by an order of magnitude because the destination tables contain much less data than the source tables, thereby offering faster and cheaper data access and storage.

AWS Fargate Interview Questions and Answers

Ques. 6): What are data from time series?

Answer:

A time series is a collection of data points that are collected over a period of time to track changing events. Examples include changes in stock prices over time, temperature readings over time, and an EC2 instance's CPU usage over time. Each data point in a time-series consists of an event that changes over time, one or more attributes, and a timestamp. This data is utilised to spot abnormalities, find chances for improvement, and gain insights into the functionality and health of an application. DevOps engineers, for instance, might be interested in data that tracks changes in infrastructure performance metrics, manufacturers might be interested in IoT sensor data that tracks equipment changes throughout a facility, and online marketers might be interested in clickstream data that records a user's website navigation over time. Time series data must be cost-effectively collected in close to real-time, produced in extremely high volumes from a variety of sources, and stored in a way that makes it easy to organise and analyse.

When data is saved, Amazon Timestream divides it into sections based on time and other factors, speeding up data access with a specially designed index. Additionally, by providing an in-memory storage for recent data, a magnetic store for historical data, and by allowing configurable rules to automatically migrate data from the memory store to the magnetic store as it reaches a specific age, Amazon Timestream automates the lifecycle management of data. As a result, you can quickly and effectively use SQL to extract insights from your data using Amazon Timestream's purpose-built adaptive query engine, which can seamlessly access and integrate data across storage tiers without requiring you to identify the data location. Finally, Amazon Timestream makes it simple for you to integrate Amazon Timestream into your time series solutions by integrating easily with your choice data collecting, visualisation, analytics, and machine learning services.

AWS Solution Architect Interview Questions and Answers

AWS Glue Interview Questions and Answers

Ques. 11): How do I handle data about upcoming or delayed arrivals?

Answer:

Data with a timestamp in the past is referred to as late arrival data. Data with a timestamp in the future is referred to as future data. Both types are accessible and storable via Amazon Timestream.

Simply enter the information to be stored as late arrival data into Amazon Timestream, and the service will choose whether to write it to the memory store or the magnetic store depending on the timestamp and the specified data retention for the memory and magnetic stores.

Model your data as a multi-measure record with the future timestamp represented as a measure inside the record if you want to store future data.
