Brief introductionThe Binascii module contains a number of binary representations that are used to convert binary and various ASCII encodings. These features are not typically used directly, but instead are encapsulated modules such as UU, Base64, or BinHex. The Binascii module contains faster, lower-level features written in C that are typically used by advanced modules.
Features: binary and ASCII conversion.
Type: standard module

Issue 1 Java ApI performs append write: Cannot write
Problem Description:① The current data node cannot be written, the ② append file needs to be requested again.

We can't just output this, because the CRC code is chaotic.If I use "echo $contents" here, the compressed data

If the support is X-gzip, then the head below will be replaced with Z-gzip

any number of slave nodes, which are used to replace the primary node when the primary node is disconnected or the node fails.
The following is the algorithm that is responsible for mapping keys to slots:
Hash_slot = CRC16 (key) mod 16384
The following parameters are used by the algorithm:
