- The Appender can be used to load bulk data into a DuckDB database. It is available in the C, C++, Go, Java, Julia, Node.js, Python, and Rust clients. This page describes how the Appender behaves across clients and shows a minimal example in
...R)"); Appender appender(con, "people"); appender.AppendRow(1, "Mark"); Rows can also be individually constructed using the BeginRow , EndRow , and Append methods. This is done internally by AppendRow , and hence has the same performance characteristics:...appender.BeginRow(); appender.Append<int32_t>(2); appender.Append<string>("Hannes"); appender.EndRow(); For more information, see the C++ cl...ient . Java (JDBC) An appender is created from a DuckDBConnection with createAppender() , and rows are built with beginRow() , append() , and endRow() .
