fix: Adjust binlog and parquet reader buffer size for import (#43495) 
1. Modify the binlog reader to stop reading a fixed 4096 rows and
instead use the calculated bufferSize to avoid generating small binlogs.
2. Use a fixed bufferSize (32MB) for the Parquet reader to prevent OOM.

Data Node

DataNode is the component to write insert and delete messages into persistent blob storage, for example MinIO or S3.

Dependency

  • KV store: a kv store that persists messages into blob storage.
  • Message stream: receive messages and publish information
  • Root Coordinator: get the latest unique IDs.
  • Data Coordinator: get the flush information and which message stream to subscribe.
