Last week, OpenAI revealed their new toy ChatGPT. Suddenly, my social network is overwhelmed with all sorts of ChatGPT conversations. Regardless of how weird the questions are, ChatGPT always sounds convincing, even though sometimes it's just nonsense. Below I start a conversation asking ChatGPT the database I should choose for my next software project. I picked this topic because:
- Comparing different databases always causes heated debate. I am curious how the state-of-the-art AI handles this.
- I know this domain decently well, so I could escape from the ChatGPT persuasive trap (hopefully).
Scripts
Me: I want to start a new software project, which database should I choose, MySQL, PostgreSQL, Mango, SQLite or others?
ChatGPT: There are many factors to consider when choosing a database for your software project, including the type of project you are building, your budget, and the level of performance and scalability you need. MySQL, PostgreSQL, MongoDB, and SQLite are all popular database options, each with their own strengths and weaknesses.
Me: Tell me the strengths and weaknesses among them
ChatGPT: MySQL is a widely-used, open-source relational database management system (RDBMS) that is known for its ease of use and strong performance. One of its main advantages is that it supports a wide range of applications, from small websites to large, complex systems. However, MySQL is not always the best choice for high-performance applications, and it does not support some advanced database features such as document-level data handling and native graph data storage.
PostgreSQL is another popular open-source RDBMS that is known for its reliability, stability, and support tore wide range of data types. It is often used in mission-critical applications, and it supports advanced features such as data replication and concurrency without read locks. However, PostgreSQL can be more complex to set up and manage than some other database options, and it may not be the best choice for applications that require very high performance.
MongoDB is a popular open-source NoSOL database that is known for its flexibility and scalability. It is often used in applications that require the ability to store and query large volumes of unstructured data, and it supports advanced features such as distributed data storage and indexing. However, MongoDB can be more complex to use than some other database options, and it may not be the best choice for applications that require ACID (atomic, consistent, isolated, durable) transactions.
SQLite is a widely-used, open-source RDBMS that is known for its lightweight design and good performance. It is often used in embedded applications, such as mobile apps, and it does not require a separate server process to operate. However, SQLite does not support advanced database features such as data replication and distributed data storage, and it may not be the best choice for applications that require high levels of performance or scalability.
Ultimately, the best database for your project will depend on your specific requirements and goals. It's a good idea to research and compare different database options carefully before making a decision.
Me: OK, I will go with PostgreSQL, which cloud provider should I choose, AWS, GCP or Microsoft Azure
ChatGPT: All three of the major cloud providers-- Amazon Web Services (AWS), Google Cloud Platform (GCP), and Microsoft Azure -- offer support for PostgreSQL. Each of these platforms has its own strengths and weaknesses, so the best choice for you will depend on your specific needs and requirements.
AWS offers a fully managed version of PostgreSQL called Amazon RDS for PostgreSQL, which makes it easy to set up, operate, and scale a PostgreSQL database in the cloud. AWS also offers a range of other services and tools that can be used in conjunction with PostgreSQL, such as Elastic Load Balancing for high availability and Amazon Redshift for data warehousing.
GCP offers a fully managed version of PostgreSQL called Cloud SOL for PostgreSQL, which makes it easy to set up, operate, and scale a PostgreSQL database in the cloud. GCP also offers a range of other services and tools that can be used with PostgreSQL, such as BigQuery for data analytics and Cloud Pub/Sub for event-driven architecture.
Microsoft Azure offers a fully managed version of PostgreSQL called Azure Database for PostgreSQL, which makes it easy to set up, operate, and scale a PostgreSQL database in the cloud. Azure also offers a range of other services and tools that can be used with PostgreSQL, such as Azure Synapse Analytics for data warehousing and Azure Cosmos DB for globally distributed data.
In summary, all three of these cloud providers offer robust support for PostgreSQL and a range of other services that can be used in conjunction with a PostgreSQL database. The best choice for you will depend on your specific needs and requirements, as well as any existing investments you may have in a particular cloud platform. It's a good idea to research and compare the offerings from each provider carefully before making a decision.
Me: What are the available regions and respective prices for each cloud vendor?
ChatGPT: I'm sorry, but I am not able to browse the internet, so I cannot provide you with information about the available regions and prices for each cloud provider. I am a large language model trained by OpenAl, and my knowledge is based on the text that has been fed to me. I am not able to access real-time information or browse the internet like a human.
Luckily, ChatGPT is not capable of answering this, otherwise, our DB Cost website would be wasted.
Me: If I want to combine OLTP and OLAP together, what's your recommendation? (Poke some recent development in the database industry)
ChatGPT: If you want to combine online transaction processing (OLTP) and online analytical processing (OLAP) in your database, one option is to use a hybrid transactional/analytical processing (HTAP) database. HTAP databases are designed to support both OLTP and OLAP workloads simultaneously, allowing you to perform real-time analytics on your transactional data without having to replicate or move the data to a separate OLAP system.
There are several HTAP databases available, including MemSQL, NuoDB, and ClustrixDB. These databases combine the performance and scalability of in-memory architectures with the reliability and durability of disk-based storage, making them well-suited for applications that require real-time analytics on high-volume, transactional data.
Another option is to use a data warehousing solution, such as Amazon Redshift, Google BigQuery, or Microsoft Azure Synapse Analytics. These solutions allow you to load and store your transactional data in a separate, optimized environment for analytics, while still providing real-time access to the data for reporting and other business intelligence needs.
Ultimately, the best approach for combining OLTP and OLAP in your database will depend on your specific requirements and goals. It's a good idea to research and compare different solutions carefully before making a decision.
Me: I want a free, HTAP, Serverless, MySQL and PostgreSQL compatible database, what do you recommend? (Being intentionally unreasonable and want to see how ChatGPT would respond)
ChatGPT: I'm sorry, but it is unlikely that you will be able to find a free, HTAP, serverless, MySQL and PostgreSQL compatible database. Hybrid transactional/analytical processing (HTAP) databases are designed to support both online transaction processing (OLTP) and online analytical processing (OLAP) workloads simultaneously, and they typically require specialized hardware and software to operate. Additionally, MySQL and PostgreSQL are both widely-used, open-source relational database management systems (RDBMS), and it is unlikely that any free database solution would be compatible with both of them.
If you are looking for a free database solution, you may want to consider using SQLite, which is a lightweight, open-source RDBMS that does not require a separate server process to operate. SQLite is often used in embedded applications, such as mobile apps, and it is capable of supporting small to medium-sized datasets. However, it does not support advanced database features such as distributed data storage and indexing, and it may not be suitable for applications that require high levels of performance or scalability.
Alternatively, you could consider using a cloud-based database solution, such as Amazon Web Services (AWS) Aurora Serverless, which is a fully managed, serverless, MySQL and PostgreSQL compatible database. AWS Aurora Serverless can automatically scale up or down based on your workload, allowing you to pay only for the compute and storage resources you use. However, AWS Aurora Serverless is not a HTAP database, and it is not free. It is offered on a pay-as-you-go basis, with pricing based on the amount of storage, compute, and I/O resources you use.
In summary, while it is possible to find free database solutions, it is unlikely that you will be able to find a free, HTAP, serverless, MySQL and PostgreSQL compatible database. The best solution for your needs will depend on your specific requirements and goals, as well as your budget and level of technical expertise. It's a good idea to research and compare different options carefully before making a decision.
Me: OK, what if I only need either MySQL or PostgreSQL compatible? (Soften the requirement a bit)
ChatGPT: If you only need a database that is compatible with either MySQL or PostgreSQL, you may want to consider using a cloud-based database solution, such as Amazon Web Services (AWS) Aurora, Google Cloud SQL, or Microsoft Azure Database for MySQL or PostgreSQL. These solutions are fully managed, scalable, and compatible with the MySQL and PostgreSQL open-source databases, respectively. They allow you to set up, operate, and scale a MySQL or PostgreSQL database in the cloud without having to manage the underlying infrastructure yourself.
AWS Aurora is a fully managed, scalable, MySQL and PostgreSQL compatible database that is offered on a pay-as-you-go basis. It can automatically scale up or down based on your workload, allowing you to pay only for the compute and storage resources you use. AWS also offers a serverless version of Aurora called Aurora Serverless, which can automatically scale up or down based on demand, and does not require you to provision any capacity in advance.
Google Cloud SQL is a fully managed, scalable, MySQL and PostgreSQL compatible database that is offered on a pay-as-you-go basis. It allows you to set up, operate, and scale a MySQL or PostgreSQL database in the cloud, and it offers high availability and disaster recovery options to protect your data.
Microsoft Azure Database for MySQL and PostgreSQL are fully managed, scalable, MySQL and PostgreSQL compatible databases that are offered on a pay-as-you-go basis. They allow you to set up, operate, and scale a MySQL or PostgreSQL database in the cloud, and they offer a range of options for managing and securing your data.
In summary, if you only need a database that is compatible with either MySQL or PostgreSQL, there are many cloud-based options available. These solutions are fully managed, scalable, and compatible with the open-source MySQL and PostgreSQL databases, respectively. They allow you to set up, operate, and scale a MySQL or PostgreSQL database in the cloud without having to manage the underlying infrastructure yourself. The best option for you will depend on your specific requirements and goals, as well as your budget and level of technical expertise. It's a good idea to research and compare different solutions carefully before making a decision.
Me: But those are for OLTP, while I ask for an HTAP, serverless database. (Keep pressing again)
ChatGPT: I'm sorry, but the cloud-based database solutions mentioned earlier, such as Amazon Web Services (AWS) Aurora, Google Cloud SQL, and Microsoft Azure Database for MySQL or PostgreSQL, are not hybrid transactional and analytical processing (HTAP) databases. They are designed to support online transaction processing (OLTP) workloads, and they do not support online analytical processing (OLAP) workloads.
HTAP databases are designed to support both OLTP and OLAP workloads simultaneously, allowing you to perform real-tints analytics on your transactional data without having to replicate or move the data to a separate OLAP system. However, HTAP databases are not typically offered as a fully managed, serverless solution in the cloud. They require specialized hardware and software to operate, and they are typically deployed on-premises or in a private cloud.
If you are looking for a free, HTAP, serverless database, it is unlikely that you will be able to find one. HTAP databases are complex, high-performance systems that require specialized hardware and software to operate, and they are not typically offered as a free or serverless solution. If you need a HTAP database, you may want to consider using a commercial HTAP database solution, such as MemSQL, NuoDB, or ClustrixDB. These solutions are not free, but they offer a fully managed scalable, HTAP database that can be used on-premises or in a private cloud.
In summary, the cloud-based database solutions I mentioned earlier, such as AWS Aurora, Google Cloud SQL, and Azure Database for MySQL or PostgreSQL, are not HTAP databases. They are designed to support OLTP workloads, and they do not support OLAP workloads. It you are looking tore free, HTAP, serverless database, it is unlikely that you will be able to find one. You may want to consider using a commercial HTAP database solution instead.
Me: Alright, good try. You are spared.
ChatGPT: Thank you for your understanding. As a large language model trained by OpenAl, my goal is to provide accurate and helpful information to the best of my ability. I am not able to browse the internet or access real-time information, so I may not always be able to provide detailed or up-to-date answers to your questions. If you have any further questions, please don't hesitate to ask. I will do my best to help.
Overall Impression
I am impressed.
ChatGPT can understand and engage the conversation like a real human. For such a technical question, ChatGPT's answer is mostly sane, albeit a bit out-dated. e.g. When asking for the HTAP databases, it mentions MemSQL (which has already been rebranded to SingleStore) and dissolved NuoDB, ClustrixDB, but ignores the starlet like TiDB. This is understandable as ChatGPT confesses that its knowledge cutoff is September 2021, after I ask it to brief the AWS re:Invent 2022 happened just days ago.
I believe the knowledge freshness gap will be shortened dramatically in the coming years, just like the data analysis industry, where those analysis taking days and weeks before now just take minutes if not instant.
ChatGPT's tone is also convincing and diplomatic. e.g. When talking about MongoDB, it says
it may not be the best choice for applications that require ACID (atomic, consistent, isolated, durable) transactions.
It didn't say MongoDB doesn't support ACID (which would be incorrect). In real database debate, such subtle mistake will cost the whole battle.
As ChatGPT progresses, I expect it could give database suggestions as good as any database veterans. And we may all retire at that point regardless of whether willingly or not.
