Kudu vs Microsoft SQL Server: What are the differences?
Introduction: Here are the key differences between Kudu and Microsoft SQL Server.
Storage Model: Kudu stores data in columnar format, optimized for fast analytics queries, while Microsoft SQL Server stores data in row-based format, suitable for transactional workloads.
Query Language: Kudu uses Apache Impala for querying data, which supports SQL-like queries for faster data retrieval, whereas Microsoft SQL Server uses T-SQL, a powerful query language with a wide range of functionalities.
Scalability: Kudu is designed for horizontal scalability, allowing users to easily add more nodes to increase performance and capacity, whereas Microsoft SQL Server's scalability is limited by the capacity of a single server.
Real-Time Processing: Kudu is well-suited for real-time processing and stream processing applications, with features like Write-Ahead Logging (WAL) for durability and reliability, while Microsoft SQL Server is more focused on traditional batch processing.
Data Consistency: Kudu provides strong consistency guarantees with its MVCC (Multi-Version Concurrency Control) implementation, ensuring that the data is always in a consistent state, whereas Microsoft SQL Server offers different levels of isolation depending on the transaction requirements.
Integration with Ecosystem: Kudu seamlessly integrates with the Apache Hadoop ecosystem, allowing for easy integration with tools like Apache Spark, Apache Hive, and Apache Flume, while Microsoft SQL Server has its ecosystem of tools and services, making it easier to work with other Microsoft products.
In Summary, Kudu and Microsoft SQL Server differ in terms of storage model, query language, scalability, real-time processing capabilities, data consistency, and integration with different ecosystems.
I am a Microsoft SQL Server programmer who is a bit out of practice. I have been asked to assist on a new project. The overall purpose is to organize a large number of recordings so that they can be searched. I have an enormous music library but my songs are several hours long. I need to include things like time, date and location of the recording. I don't have a problem with the general database design. I have two primary questions:
- I need to use either MySQL or PostgreSQL on a Linux based OS. Which would be better for this application?
- I have not dealt with a sound based data type before. How do I store that and put it in a table? Thank you.
Hi Erin,
Honestly both databases will do the job just fine. I personally prefer Postgres.
Much more important is how you store the audio. While you could technically use a blob type column, it's really not ideal to be storing audio files which are "several hours long" in a database row. Instead consider storing the audio files in an object store (hosted options include backblaze b2 or aws s3) and persisting the key (which references that object) in your database column.
Hi Erin, Chances are you would want to store the files in a blob type. Both MySQL and Postgres support this. Can you explain a little more about your need to store the files in the database? I may be more effective to store the files on a file system or something like S3. To answer your qustion based on what you are descibing I would slighly lean towards PostgreSQL since it tends to be a little better on the data warehousing side.
Hi Erin! First of all, you'd probably want to go with a managed service. Don't spin up your own MySQL installation on your own Linux box. If you are on AWS, thet have different offerings for database services. Standard RDS vs. Aurora. Aurora would be my preferred choice given the benefits it offers, storage optimizations it comes with... etc. Such managed services easily allow you to apply new security patches and upgrades, set up backups, replication... etc. Doing this on your own would either be risky, inefficient, or you might just give up. As far as which database to chose, you'll have the choice between Postgresql, MySQL, Maria DB, SQL Server... etc. I personally would recommend MySQL (latest version available), as the official tooling for it (MySQL Workbench) is great, stable, and moreover free. Other database services exist, I'd recommend you also explore Dynamo DB.
Regardless, you'd certainly only keep high-level records, meta data in Database, and the actual files, most-likely in S3, so that you can keep all options open in terms of what you'll do with them.
Hey Erin! I would recommend checking out Directus before you start work on building your own app for them. I just stumbled upon it, and so far extremely happy with the functionalities. If your client is just looking for a simple web app for their own data, then Directus may be a great option. It offers "database mirroring", so that you can connect it to any database and set up functionality around it!
Hi Erin,
- Coming from "Big" DB engines, such as Oracle or MSSQL, go for PostgreSQL. You'll get all the features you need with PostgreSQL.
- Your case seems to point to a "NoSQL" or Document Database use case. Since you get covered on this with PostgreSQL which achieves excellent performances on JSON based objects, this is a second reason to choose PostgreSQL. MongoDB might be an excellent option as well if you need "sharding" and excellent map-reduce mechanisms for very massive data sets. You really should investigate the NoSQL option for your use case.
- Starting with AWS Aurora is an excellent advise. since "vendor lock-in" is limited, but I did not check for JSON based object / NoSQL features.
- If you stick to Linux server, the PostgreSQL or MySQL provided with your distribution are straightforward to install (i.e. apt install postgresql). For PostgreSQL, make sure you're comfortable with the pg_hba.conf, especially for IP restrictions & accesses.
Regards,
I recommend Postgres as well. Superior performance overall and a more robust architecture.
