A new query is added
LOAD PARQUET FROM.... New libraryarrowis added which is built throughlibsfolder functionality. Loading parquet files uses a prefetcher thread which operates in column batches and from such column-wise oriented data, assembles rows which the main execution thread at the end just pulls. That's how we hide the cost of assembling rows from column-oriented data. To avoid copying allocated data from the background thread to the main thread, we make use of thread-safe memory resource. A new data queue is added which is used as a shared resource between the prefetcher and the main thread.The class
utils::Datesupports instantiation now using the number of days and the number of microseconds passed since UNIX epoch.
