Header file for the Json_diff class.
The Json_diff class is used to represent a logical change in a JSON column, so that a replication master can send only what has changed, instead of sending the whole new value to the replication slave when a JSON column is updated.

The result of applying JSON diffs on a JSON value using apply_json_diff().
enum_json_diff_status apply_json_diff | ( | const Json_diff & | diff, |
Json_dom * | dom | ||
) |
Apply one JSON diff to the DOM provided.
diff | The diff which contains the path to apply it and the new value. |
dom | The DOM to apply the diff to. |
std::optional< ReadJsonDiffResult > read_json_diff | ( | const unsigned char * | pos, |
size_t | length | ||
) |
Read one JSON diff from a buffer.
pos | The position to start reading from in the buffer. When the function returns, it will be set to the position right after the last byte read. |
length | The maximum number of bytes to read from the buffer. |
|
static |
