    The questionably named Cloudera Navigator Optimizer

    I only have mixed success at getting my clients to reach out to me for messaging advice when they’re introducing something new. Cloudera Navigator Optimizer, which is being announced along with Cloudera 5.5, is one of my failures in that respect; I heard about it for the first time Tuesday afternoon. I hate the name.

    Metamarkets’ back-end technology

    This is part of a three-post series:

    By “get data read to be put into Druid” I mean:

    That metadata is what goes into the MySQL database, which also retains data about shards that have been invalidated. (That part is needed because of the MVCC.)

    By “build the data segments” I mean:

    When things are being done that way, Druid may be regarded as comprising three kinds of servers: Read more
