ORC-1615: Fix Broken hyperlinks (#17) ### What changes were proposed in this pull request? The PR aims at fixing broken hyperlinks in the ORC Format specification ### Why are the changes needed? The changes are need to avoid 404 errors ### How was this patch tested? Manually verified
ORC is a self-describing type-aware columnar file format designed for Hadoop workloads. It is optimized for large streaming reads, but with integrated support for finding required rows quickly. Storing data in a columnar format lets the reader read, decompress, and process only the values that are required for the current query. Because ORC files are type-aware, the writer chooses the most appropriate encoding for the type and builds an internal index as the file is written. Predicate pushdown uses those indexes to determine which stripes in a file need to be read for a particular query and the row indexes can narrow the search to a particular set of 10,000 rows. ORC supports the complete set of types in Hive, including the complex types: structs, lists, maps, and unions.
This project includes ORC specifications and the protobuf definition. Apache ORC Format 1.0.0
is designed to be used for Apache ORC 2.0+
