Connectorname: MySQL
host: Hostname or IP address of the server
port: Server running port
username: Username
password: Password
database: Database
drivername: mysql+pymysql

Configure the Bold Data Hub to connect MySQL

Configuration Parameters

Parameters Description
Host: Specify the hostname of the MySQL server.
Port: Specify the port number of the MySQL server (default is 3306).
Username: Provide the username to authenticate with the MySQL server.
Password: Provide the password to authenticate with the MySQL server.
Database: Specify the name of the MySQL database from which data will be extracted.
Driver Name: Specify the driver name for connecting to MySQL (e.g., mysql+pymysql).
Select: Tablename(s): Specify the table name list to load tables from the MySQL server.
Metadata: (Optional) Replication Method: Specify the replication method for the table(s). Options include FULL or INCREMENTAL.
Replication Key: Specify the replication key for incremental replication. This key helps in identifying new or updated records.
Replication Value: Specify the replication value to start the incremental replication from a particular point.
  1. Update the details required in the template and Click Save, choose the desired destination to save the pipeline.

MySQL Data Hub- BoldBI

  1. Creating a Pipeline in Bold Data Hub automatically creates a Data Source in Bold BI. The Bold BI Data Source is a live data source to the destination database used in Bold Data Hub. For more information on the relationship between Bold Data Hub Pipeline and the associated Data Sources in Bold BI , please refer to Relationship between Bold Data Hub Pipeline and Associated Data Sources in Bold BI

Schedule Bold Data Hub Job

  1. To configure interval-based scheduling, click on the schedules tab and select the created pipeline and click on the schedule icon and configure it.

Metadata Properties

In the metadata section, define the mode of data refresh. There are two modes: INCREMENTAL and FULL_TABLE. It only supports DateTime datatype columns.

INCREMENTAL

This mode fetches data from the date column mentioned in the replication key from the start date as mentioned in the replication value. Once it is scheduled, the replication value is updated automatically from the imported data.

metadata:
  TableName:
    replication_method: INCREMENTAL
    replication_key: Column name
    replication_value: column value that data starts from

FULL_TABLE

This mode fetches data from the date column mentioned in the replication key from the start date as mentioned in the replication value. Once it is scheduled, the replication value is updated based on the interval_type and interval_value from the imported data. For ex set interval_type as ‘year’ and intervalue value as ‘1’.In first schedule, will fetch the record from Jan 1, 2000 to Dec 31, 2000. In next schedule, will fetch the record from Jan 1, 2001 to Dec 31, 2001 and so on.

metadata:
  TableName:
    replication_method: FULL_TABLE
    replication_key: Column name
    replication_value: column value that data starts from
    interval_type: days/hours/minutes/year/month
    interval_value: integer value to add in interval type
