What are the cons of using unbuffered queries in Dapper?

  • Slower Access: Since data is loaded one row at a time, it may take longer to access all the data compared to a buffered query where all the data is loaded into memory at once.
  • Connection Duration: The connection to the database remains open until all data has been read, potentially keeping the connection open longer than with a buffered query, particularly with large result sets.
  • Complexity: Handling unbuffered queries can be slightly more complex than handling buffered queries, particularly in scenarios where you need to manage the open connection for a longer period.
  • Partial Data: If an error occurs midway through an unbuffered read, you may end up with only a portion of the expected data.
  • Memory Management: While unbuffered queries are more memory-efficient for large data sets, for small data sets, the overhead of managing the "streaming" of data could potentially use more resources than simply loading all the data into memory.
