> Sql. Introduce script parser service
> ------------------------------------
>
> Key: IGNITE-20764
> URL: https://issues.apache.org/jira/browse/IGNITE-20764
> Project: Ignite
> Issue Type: Improvement
> Reporter: Pavel Pereslegin
> Assignee: Pavel Pereslegin
> Priority: Major
>
> 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 second implementation, which, in addition to the total number of
> dynamic parameters (for validation), returned a list of parsing results for
> each statement (with the correct number of dynamic parameters). of the script
