we are doing project using php and cassandra? if any already finished project using PHP and CASSANDRA available means that will help ful for reference. is there is any sample project available? and facebook uses cassandra. so how can we get some inputs from facebook experience and tools? is facebook maintain as opened?
A:
facebook uses cassandra ONLY for the keywords extracted from your messages for a search index so you can find your messages faster. the only reason they can use cassandra for this is that it doesnt matter if data gets lost. which is the biggest problem of cassandra because it's not ACID compatible. they do NOT use it as a database.
cassandra is really advanced - just by asking this i know you will go crazy with the non existing documentation nor any good examples - rather look into mongodb, couchDB.

where to start. statements that are wrong in the answer above, 1, they use it as a database. 2, data does not "get lost" (hint eventual consistency). 3, plenty of documentation (e.g the riptano blog/documentation, and ofcourse the apache cassandra wiki). look into mongo or couch, i rest my case.
