    hihi... do you have notes how to relocate the Derbydb files onto persistnt storage, thus allowing for the container to be killed, recreate and the metastore it had persists. At the moment imoved the DerbyDB off to PostgreSQL but it adds weight/complexity to the build.

    I had a question here sir .... So the logical Plan which is created by Catalyst Optimizer can we called it a Linage and same goes for physical plan can we call it as DAG ?

    • @blismosacademy
      @blismosacademy 7 місяців тому

      No, lineage and logical plan are not the same. Lineage in Spark refers to the sequence of transformations that lead to the creation of a DataFrame or RDD (Resilient Distributed Dataset), whereas the logical plan is an abstract representation of the query or operations to be performed, which can be either resolved or unresolved. Yes, the DAG (Directed Acyclic Graph) is based on the physical plan, which is Spark's final execution plan.

    This finally cleared up the issues I was having understanding the abstraction layer Hive represents. I understood Hive was a collection of data in HDFS, or some other distributed file system, but I was confused on how that was, why it was and what it did to make that work. I knew the meta store played a role but I was also confused on how data even gets inserted into hive because it feels like a database so again, that abstraction was confusing. This video cleared it all up! You earned a sub. Thanks a ton.

    It's worth knowing that you can use cat > a_file_name and then type the contents of the file at the command line, like using a heredoc in a script. (I like doing this when writing short scripts as I can see the contents of the terminal as I write it, and it is a good challenge in thinking before you type.)
