Log plugin related bug

local function remove_stale_objects(premature)
    if premature then
        return
    end

    for key, batch in ipairs(buffers) do
        if #batch.entry_buffer.entries == 0 and #batch.batch_to_process == 0 then
            core.log.warn("removing batch processor stale object, conf: ",
                          core.json.delay_encode(key))
            buffers[key] = nil
        end
    end

    stale_timer_running = false
end

why use "ipairs" here to polling, the "ipairs" whill pass the map, is it a bug? Should use "pairs"?

The buffer is an array-like table, so use ipairs to fetch each of them.

I debug it, and found it is map-like table, it's key and value is set in the function _M.log(conf, ctx)
