MySQL to StarRocks Example

Here we use an example to introduce how to use Apache InLong creating MySQL -> StarRocks data synchronization.

Deployment

Install InLong

Before we begin, we need to install InLong. Here we provide two ways:

• Docker Deployment (Recommended)
• Bare Metal Deployment

Add Connectors

Download the connectors corresponding to Flink version, and after decompression, place sort-connector-starrocks-[version]-SNAPSHOT.jar in /inlong-sort/connectors/ directory.

Install StarRocks

Please refer to the Installation Tutorial on the StarRocks official website

Cluster Initialize

When all containers are successfully started, you can access the InLong dashboard address http://localhost, and use the following default account to log in.

User: admin
Password: inlong

Register StarRocks DataNodes

Click [DataNodes] -> [Create] on the page to register StarRocks DataNodes.

note

• Please do not fill in http:// for LOAD URL, just fill in IP:PORT.

Create Task

Create Data Streams Group

Click [Synchronization] → [Create] on the page and input the Group ID, Stream ID and Full database migration:

Create Data Source

In the data source, click [New] → [MySQL] to configure the source name, address, databases and tables information.

note

• When the read mode is selected as Full + Incremental, the existing data in the table will also be collected, but not in the Incremental mode.
• The table white list format is <dbName>.<tableName> and supports regular expressions.

Create Data Sink

In the data sink, click [New] → [StarRocks] to configure the sink name, database name, table name and created StarRocks data node.

Approve Data Stream

Click [Approval] -> [MyApproval] -> [Approval] -> [Ok].

Back to [Synchronization] page, wait for [success].

Test Data

Send Data

#!/bin/bash
# MySQL info
DB_HOST="mysql"
DB_USER="root"
DB_PASS="inlong"
DB_NAME="test"
DB_TABLE="source_table"
# Insert data in a loop
for ((i=1; i<=1000; i++))
do
    # Generate data
    id=$i
    name="name_$i"
    # Build an insert SQL
    query="INSERT INTO $DB_TABLE (id, name) VALUES ($id, '$name');"
    # Execute insert SQL
    mysql -h $DB_HOST -u $DB_USER -p$DB_PASS $DB_NAME -e "$query"
done

Modify the variables in the script according to the actual environment, and add a total of 1000 pieces of data to the source_table:

Verify Data

Enter StarRocks, check data in sink_table.
