[jira] [Updated] (IGNITE-18478) .NET: Thin 3.0: Add ExecuteReader to SQL API
[ https://issues.apache.org/jira/browse/IGNITE-18478?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Pavel Tupitsyn updated IGNITE-18478:
------------------------------------
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>`.
