New features
| Feature | Description | References |
|---|---|---|
| File system result tables | The file system connector writes data from partitioned files in a specified file format to Object Storage Service (OSS). It creates a directory for each partition and rolls files based on a rolling policy. | Create a file system result table |
Performance optimization
| Feature | Description | References |
|---|---|---|
| Improved MaxCompute write performance | The MaxCompute connector introduces two parameters: numFlushThreads controls the number of threads used to flush data in a MaxCompute Tunnel writer buffer, and batchSize controls the flush interval for that buffer. Tuning these parameters improves write performance to MaxCompute. |
