This is a "modern" log writer, i.e.
it doesn't care what type a log_item on an error log event is; as long as it's one of the wellknown classes (string, float, int), it can and will write it.
By default, each line will contain one log event, in a format somewhat similar to that emitted by "journalctl -o json" on platforms that use systemd's journal:
{ "prio" : 2, "err_code" : 3581, "msg" : "Parser saw: SET @@global.log_error_filter_rules= DEFAULT", "err_symbol" : "ER_PARSER_TRACE", "label" : "Note" } { "prio" : 2, "err_code" : 3581, "subsystem" : "parser", "SQL_state" : "XX999", "source_file" : "sql_parse", "function" : "dispatch_command", "msg" : "Parser saw: SELECT \"logging as traditional MySQL error log and as JSON"", "time" : "1970-01-01T00:00:00.000000Z", "thread" : 0, "err_symbol" : "ER_PARSER_TRACE", "label" : "Note" }
Pretty-print (with indents and line-breaks between key/value pairs), or one event per line? jq for example doesn't mind, but we play it safe by defaulting to the latter; this is also the format that "journalctl -o json" renders on platforms that use systemd's journal.
