[PATCH v1 17/25] structured-logging: add aux-data for index size

From: git@jeffhostetler.com <git@jeffhostetler.com>
Date: Jul 13, 2018, 16:56 UTC
Message-ID: <20180713165621.52017-18-git@jeffhostetler.com>
In-Reply-To: <20180713165621.52017-1-git@jeffhostetler.com>

From: Jeff Hostetler <jeffhost@microsoft.com>

Teach do_read_index() and do_write_index() to record the size of the index in aux-data. This will be reported in the "cmd_exit" event.
