From f53cdab3d7627c2dc16dd0089c956676d7e50f55 Mon Sep 17 00:00:00 2001 From: Steven Fackler Date: Mon, 6 Apr 2020 17:38:59 -0700 Subject: [PATCH] Hex encode keys in compaction flush logs (#6616) Summary: The raw key bytes are currently dumped directly into the log messages, which is not ideal if the keys aren't ASCII strings. Null bytes in particular can cut off bits of the message early.
