Fivetran supports MySQL database as a destination. MySQL is not typically used as a data warehouse because it is a row-based database more suited to transactional use-cases. Large analytical querying is much faster on columnar warehouses.
WARNING: MySQL database can fail to perform basic queries for even medium volumes of data and is not appropriate as a data warehouse. We support MySQL database as a test environment. If you run into these limitations, you will need to migrate to a supported destination.
Fivetran supports connecting with five different MySQL implementations:
Type transformation mappinglink
The data types in your MySQL database follow Fivetran’s standard data type storage.
We use the following data type conversions:
|Fivetran Data Type||Destination Data Type||Notes|
|INSTANT||TIMESTAMP||For MySQL version 5.7 or later, we convert INSTANT to TIMESTAMP(6). MySQL’s TIMESTAMP data type range begins with
|STRING||LONGTEXT or VARCHAR(b)||We convert STRING:
|JSON||JSON||For versions prior to MySQL version 5.7.8, we convert JSON to TEXT because previous versions don’t support JSON.|
|BINARY||LONGBLOB or VARBINARY(b)||We convert BINARY:
IMPORTANT: MySQL databases with versions less than 5.7 don’t support fractional timestamps. Fivetran skips source tables from a sync if a table has a TIMESTAMP primary key column or if you activated History Mode for the table.
Follow our step-by-step setup guides for specific instructions on how to set up your MySQL database as a destination:
Primary key creationlink
Fivetran creates primary keys for a MySQL database in either of the following scenarios:
MySQL version earlier than 5.7.7, or MariaDB version earlier than 10.2:
- If the total number of primary keys provided by the source is less than 16, and the sum of the byte length of String primary keys is less than 191.
MySQL version 5.7.7 and later, or MariaDB version 10.2 and later:
- If the total number of primary keys provided by the source is less than 16, and the sum of the byte length of String primary keys is less than 768.
Data load costslink
Whether you are self-hosting MySQL or using a managed service, you will not be charged extra when we load data into your database.
