The discussion revolves around various methods for copying SQLite databases efficiently between computers. Users highlighted the use of the SQLite session extension for change tracking and suggested that using incremental rsync might be faster than sending SQL statements. Different users shared opinions on the drawbacks, such as the need for optimization processes (e.g., running 'VACUUM') following the execution of SQL statements. Several pointed out the potential for on-the-fly compression with rsync and the advantages of using DuckDB, which can export to Parquet format for smaller file sizes. Concerns about data integrity during transfers and strategies to optimize the synchronization process were mentioned.
