Ok. The LogReader command has a mechanism to filter which tablet is displayed. If the walog has alot of data in it, may need to use this. Also, be aware that only 5 mutations are shown for a "many mutations" objects in the walog. The -m options changes this. May want to see more when deciding if the info in the log is important. > > On Tue, Jun 12, 2018 at 10:14 AM, Keith Turner <ke...@deenlo.com> wrote: >> >> Is the message you are seeing "COMPACTION_FINISH (without preceding >> COMPACTION_START)" ?
