22 * @file src/dht/plugin_dhtlog_mysql_dump.c
23 * @brief MySQL logging plugin to record DHT operations to MySQL server,
24 * but write all queries to file instead of the actual server
25 * so that they can be imported later. The idea is that connecting
26 * to the MySQL server X times can be really problematic, but hopefully
27 * writing to a single file is more reliable.
