第三,SQLite does the same autocommit, but uses fdatasync(2) on Linux, which skips syncing file metadata when compiled with HAVE_FDATASYNC (the default). This is roughly 1.6 to 2.7 times cheaper on NVMe SSDs. SQLite’s per-statement overhead is also minimal: no schema reload, no AST clone, no VDBE recompile. The Rust reimplementation does all three on every call.
此外,}The line above converts a named column reference to XN_ROWID when it matches the table’s INTEGER PRIMARY KEY column. The VDBE then triggers a SeekRowid operation instead of a full table scan, which makes the whole thing proportional to logN.,更多细节参见whatsapp
