Only the first record with a currentTransaction that is +in the list of transactions to read is returned, which corresponds to +the last visible update to a row.</p> + +<p>To support streaming ingest, we add two additional features. ORC files +may have additional footers written in to their body that is parsable +as a complete ORC file that only includes the records already +written. As the file is later extended the preliminary file footer +becomes dead space within the file. Secondly, a side file named +â*_flush_lengthâ is a small file that contains a set of 8 byte +values. The last complete 8 byte value is the end of the last +preliminary footer. </p> + +<p>Two properties are added to the metadata for ORC files to speed up the +processing of the ACID tables. In particular, when a task is reading +part of the base file for a bucket, it will use the first and last +rowIds to find the corresponding spots in the delta files.
