##Chirp Benchmark 3.0

Use the Chirp Python script to generate a benchmark file that is formatted as shown below:

00000000	w	{"UserMentions": "379961664;", "GeoLocation": null, "Hashtags": null, "ReplyToId": null, "UserID": 30363580, "IsFavorited": false, "CreationTime": 1377241159000, "MediaLinks": null, "URLLinks": null, "Source": "<a href=\"http://twitter.com/download/iphone\" rel=\"nofollow\">Twitter for iPhone</a>", "Place": null, "Text": "Tweet text removed as per Twitter policy", "IsRetweet": true, "RetweetsNum": null, "ID": 370802416255787008}
00000000	w	{"UserMentions": null, "GeoLocation": null, "Hashtags": null, "ReplyToId": null, "UserID": 1316308724, "IsFavorited": false, "CreationTime": 1377241159000, "MediaLinks": null, "URLLinks": "http://feedproxy.google.com/~r/reuters/rns_ent/~3/V4ic80GYhxw/story01.htm;", "Source": "<a href=\"http://blackberry.com/twitter\" rel=\"nofollow\">Twitter for BlackBerry\u00ae</a>", "Place": null, "Text": "Tweet text removed as per Twitter policy", "IsRetweet": false, "RetweetsNum": null, "ID": 370802416691982336}
00000000	rp	370802416691982336
00000000	rp	370802416691982336
00000000	rs	130288926
00000000	rp	370802416255787008

Each line contains of the tab-separated file:

• A timestamp, in milliseconds
• A command:
  • w for writes
  • rp for reads on primary key
  • rs for reads on secondary key
• A value:
  • a JSON tweet object for writes
  • one or two primary key(s)
  • one or two secondary key(s)

A visual walkthrough is available on the Chirp website.
