If it&#x27;s just a few streams at high frequency, my take would be to bucket it (eg every second or something) and stick it on your favorite database.  You could use postgres arrays, the json columntype, or frankly just a blob in those rows containing all the data for a second.<p>You can then write some simple postgres queries to create the views your talking about and won&#x27;t have to mess with any of the &quot;look what I wrote last week&quot; &quot;databases&quot;.
