1.9.4

One client

• Release 1.9.4 introduces the enable.streaming.client.optimization option, which is enabled by default.
• With this client optimization, only one client is created for multiple topic partitions per Kafka connector. This feature can reduce client runtime and lower migration cost by creating larger files.
• Note that in a high throughput scenario (for example, 50 MB/s per connector), we recommend that you disable this property if you see an increase in latency or costs.
