- the workload is interpreted as: when the first node receives the second byte stream sent by multiple sender nodes, if the position indication information length of each structure in the second byte stream sent by multiple sender nodes is different, Then the first node can use the method of supplementing the bytes assigned as zero to supplement the byte length of the position indication information of each structure in each second byte stream to M, so that the first node only needs to process the position of length M Indication information, that is, only one function for processing position indication information of length M needs to be generated.
- the NM bytes after the position indication information of each structure in the second byte stream are discarded, so that the length of the position indication information of each structure in the second byte stream is the same as the configuration of the first node
- the position in the information indicates that the length of the information is equal, so that the first node can process the second byte stream.
- the length of the position indication information in the second byte stream is greater than the length of the position indication information in the configuration information of the first node, which means that the version number of the third node is higher than the version number of the first node, and the second The NM bytes after the position indication information of each structure in the byte stream are discarded, which only deletes the version logic higher than the first node, and does not affect the version logic of the first node itself.
- the position indication information of each structure records the fixed length data of each structure and the variable length data of each structure in the data information.
- the position index can extract the fixed-length data and variable-length data of each structure in parallel according to the position indication information of each structure, which improves the efficiency of data deserialization.
