AWS Services are all based on SOA architectures that can be called when needed
For real-time streaming of Big data, AWS offers both legacy and full host scenarios
The legacy scenario is EC2 Deployment Flume (Capture), Kafka (data Dump), Storam (Stream processing)
The full host scenario is
java.io uses design patterns such as adapter pattern decoration mode to solve the socket and input-output problems of character streams.
A byte stream can only be processed at a time, in order to more easily manipulate the data, it adds a socket flow.
Problem Introduction:
Why is the buffer stream more efficient than ordinary file-byte throttling?
