Description

Add a new method to ISql API:

Task<IgniteDbDataReader> ExecuteReaderAsync(ITransaction? transaction, SqlStatement statement, params object?[]? args)

• IgniteDbDataReader inherits from System.Data.Common.DbDataReader, providing a standard interface to work with query results.
• DbDataReader API is an efficient way to retrieve query results without object mapping. It can be implemented in a high-performance allocation-free way. This is a good alternative to allocation-heavy IResultSet<IIgniteTuple>.
