This statement is used to specify the compression algorithm to be used for storing data in a Parquet file. In this case, the compression algorithm is LZO (Lempel–Ziv–Oberhumer), which is a lossless data compression algorithm known for its fast decompression speed. Using LZO compression can help reduce the amount of storage space needed for Parquet files while still maintaining fast query performance.
