A Solution Architect is designing a migration strategy from on-prem MySQL to Amazon Aurora.
An assessment of features compatibility must be performed.
Which engine is used by Amazon Aurora and must be taken into consideration during this analysis?
Click on the arrows to vote for the correct answer
A. B. C. D.Answer: A.
Option A is CORRECT because Amazon Aurora only supports InnoDB MySQL compatible storage engine.
Option B is incorrect because Amazon Aurora does not support the MyISAM storage engine.
Option C is incorrect because MySQL 5.4 is a MySQL version.
Amazon Aurora supports features in MySQL 5.6 and 5.7.Further, versions prior to MySQL 5.5 used MyISAM storage engine, not compatible with Amazon Aurora.
Option D is incorrect because XtraDB is a storage engine for MariaDB.Reference:
https://aws.amazon.com/rds/aurora/faqs/Amazon Aurora is a cloud-native relational database service offered by AWS. It is designed to offer high performance, high availability, and scalability while minimizing overhead and cost. Aurora is compatible with MySQL and PostgreSQL databases, but it uses a proprietary distributed storage system, which provides significant performance improvements over the traditional MySQL architecture. Aurora supports InnoDB as its default storage engine, and it is recommended to be used for optimal performance.
Therefore, the correct answer to this question is A. InnoDB.
InnoDB is a transactional storage engine for MySQL that offers row-level locking, which provides better concurrency and performance in multi-user environments. InnoDB is the default storage engine for MySQL, and it is designed to provide ACID (atomicity, consistency, isolation, and durability) compliance for transactions. Amazon Aurora uses InnoDB as its default storage engine, and it offers several performance enhancements over the traditional InnoDB implementation, including parallel query processing and distributed storage.
MyISAM is another storage engine for MySQL that offers a simpler architecture and faster read performance than InnoDB, but it lacks transactional support, which makes it less suitable for applications that require data consistency and integrity. MyISAM is not supported by Amazon Aurora.
MySQL 5.4 is a version of the MySQL database management system that was released in 2010. It is not relevant to this question, as it is not related to the compatibility of Amazon Aurora with MySQL databases.
XtraDB is a drop-in replacement for the InnoDB storage engine that is designed to offer better performance, scalability, and reliability than the standard InnoDB implementation. XtraDB is not supported by Amazon Aurora, as it is a third-party storage engine that is not compatible with the proprietary distributed storage system used by Aurora.
In conclusion, when assessing feature compatibility between an on-premises MySQL database and Amazon Aurora, it is important to take into consideration the fact that Aurora uses InnoDB as its default storage engine.
