For rate aggregations, we buffer raw input data points until all slices are processed. Buffers can be periodically flushed when the slice changes, since each slice contains all data points for a shard within a specific time range. This approach helps reduce memory pressure. However, if the number of slices is smaller than the number of active drivers, it will not help. We should partition the data into multiple reasonably sized slices. I will follow up with this change soon.
