Pavel Pereslegin updated IGNITE-20764:
--------------------------------------
Description:
At the moment, there is only one implementation ({{ParserServiceImpl}}) of the
{{ParserService}}, which is not entirely suitable for parsing scripts for
several reasons:
1. According to the {{ParserService}} interface, it returns the result of
parsing only single statement.
2. The service only counts the total number of dynamic parameters per script
(and not for the statement).
3. The cache implementation is designed to cache single expression.
To implement the script execution logic (IGNITE-20443), it is recommended to
add a new method (or second implementation), which will return a list of
parsing results for each statement (with the correct number of dynamic
parameters). of the script
