### Question:
DebeziumMySQLDatashapeStrategy implements DebeziumDatashapeStrategy { static String convertDDLtoJsonSchema(final String ddl, final String tableName) { int firstParentheses = ddl.indexOf('('); final Matcher matcher = PATTERN.matcher(ddl.substring(firstParentheses)); final List<String> properties = new ArrayList<>(); while (matcher.find()) { final String field = matcher.group(1); final String type = getType(matcher.group(2)); properties.add("\"" + field + "\":{\"type\":\"" + type + "\"}"); } return buildJsonSchema(tableName, properties); }  @Override DataShape getDatashape(Map<String, Object> params);  }### Answer:
