Bulk Uploads into KV stores are slow - so Terrapin allows KV access over immutable HDFS files. Very typical use case for recommendation systems etc. We face similar problems with latencies on HBase (At Groupon). So this solution seems interesting. Would be good to have comparison of other solutions Pinterest tried before building this. eg. loading data into Cassandra instead of HBase etc. In nutshell - very specific use case - but the one which comes across very often
