Apache seems to have 100 databases and data processing projects under its umbrella. Is there a cheat-sheet on what they do (and sometimes how they differ) and how popular they are?

Yeah, only few are actually used widely with enough feature support.

It can be divided into a few categories: 1. OLTP, thing that requires frequent updates HBase, CouchDB 2. Distributed key-value store Cassandra 3. OLAP, analytical, batch Hive, Impala 4. ETL, stream processing Spark 5. OLAP, analytical, low-latency Druid

There are a bunch of other auxiliary projects that makes deploying those things at scale feasible, such as ZooKeeper, HDFS what not....
