+- Service discovery;
+- Connection pool, buffer pool, byte pool;
+- Backoff retry;
+- Concurrently batch send;
+- Send synchronously;
+- Send asynchronously;
+- Close gracefully;
+- Hookable debug log;
+- Heartbeat;
+- Metrics;
+- Snappy compress;
+- Additional column;
+- Server offline re-balance;
