================
Comment at: clang-tools-extra/clangd/index/dex/Iterator.cpp:41
     assert(!reachedEnd() && "DOCUMENT iterator can't advance() at the end.");
+    if (peek() >= ID)
+      return;
----------------
Maybe add a short comment that this gives performance boost?
Otherwise this looks redundant when reading the code
