How to Sync to Manually
Step 1: Prepare the Environment
Begin by ensuring you have both CockroachDB and TiDB installed and running on your system. You can use Docker or native installations for this purpose. Make sure you have access credentials and network connectivity between the two databases.
Step 2: Export Data from CockroachDB
Use the `cockroach dump` command to export your database from CockroachDB. This command generates SQL statements for recreating the database schema and data. Run the following command in your terminal:
```bash
cockroach dump mydatabase --insecure --host= --port= --user= > mydatabase_dump.sql
```
Replace `mydatabase`, ``, ``, and `` with your actual database name, host address, port number, and username.
Step 3: Review and Modify SQL Dump
Open the `mydatabase_dump.sql` file in a text editor. Since TiDB is MySQL-compatible, you may need to modify certain SQL syntax to ensure compatibility. This might include changing data types or removing unsupported features.
Step 4: Create the Database in TiDB
Connect to your TiDB instance using a MySQL client (like `mysql` CLI), and create a new database:
```sql
CREATE DATABASE mydatabase;
```
Ensure that the database name matches the one used in your SQL dump.
Step 5: Import Data into TiDB
Use the MySQL client to import the modified SQL dump file into TiDB:
```bash
mysql -h -P -u -p mydatabase < mydatabase_dump.sql
```
Replace ``, ``, ``, and `mydatabase` with appropriate values for your TiDB setup.
Step 6: Verify Data Integrity
After the import is complete, verify that the data has been correctly transferred. You can do this by running sample queries and comparing results between CockroachDB and TiDB to ensure consistency.
Step 7: Optimize and Adjust Configurations
Review your TiDB configuration for any optimizations specific to your workload. Consider adjusting settings related to performance tuning, such as indexing, caching, and query execution plans to ensure optimal performance in the new environment.
By following these steps, you should be able to successfully migrate your data from CockroachDB to TiDB without using any third-party connectors or integrations.
