Fivetran supports MySQL database as a destination.

NOTE: Fivetran supports MySQL as both a database connector and 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.

Supported implementationslink

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
BOOLEAN	BOOLEAN
SHORT	SMALLINT
INT	INTEGER
LONG	BIGINT
BIGDECIMAL	DECIMAL
FLOAT	REAL
DOUBLE	DOUBLEPRECISION
LOCALDATE	DATE
LOCALDATETIME	DATETIME
INSTANT	TIMESTAMP	For MySQL version 5.7 or later, we convert INSTANT to TIMESTAMP(6). MySQL's TIMESTAMP data type range begins with `1970-01-01 00:00:01.000000` and ends with `2038-01-19 03:14:07.999999`. We convert an epoch TIMESTAMP of `1970-01-01 00:00:00` to `1970-01-01 00:00:01` because there are often primary keys with this value. We convert an epoch TIMESTAMP beyond `2038-01-19 03:14:07.999999` to `null` because primary keys rarely have such values and futuristic dates capped at 2038 can be misleading.
STRING	LONGTEXT or VARCHAR(b)	We convert STRING: If a primary key column, if `bytelength` is present, and if the MySQL version is prior to 5.7.7: If the composite primary key length is greater than 191 bytes, to LONGTEXT If the composite primary key length is less than 191 bytes, to VARCHAR(b) If a primary key column, if `bytelength` is present, and if the MySQL version is 5.7.7 or later: If the composite primary key length is greater than 768 bytes, to LONGTEXT If the composite primary key length is less than 768 bytes, to VARCHAR(b) If a primary key column and if `bytelength` is not present, to LONGTEXT If not a primary key column, to LONGTEXT
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: If a primary key column, if `bytelength` is present, and if the MySQL version is prior to 5.7.7: If the composite primary key length is greater than 191 bytes, to LONGBLOB If the composite primary key length is less than 191 bytes, to VARBINARY(b) If a primary key column, if `bytelength` is present, and if the MySQL version is 5.7.7 or later: If the composite primary key length is greater than 768 bytes, to LONGBLOB If the composite primary key length is less than 768 bytes, to VARBINARY(b) If a primary key column and if `bytelength` is not present, to LONGBLOB If not a primary key column, to LONGBLOB

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.

Setup guidelink

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.
