Apache Parquet VS TranscriptAPIYT

• Columnar Storage
  Apache Parquet uses columnar storage, which allows for efficient retrieval of only the data you need, reducing I/O and improving query performance on large datasets.
• Compression
  Parquet files support efficient compression and encoding schemes, resulting in significant storage savings and less data to transfer over the network.
• Compatibility
  It is compatible with the Hadoop ecosystem, including tools like Apache Spark, Hive, and Impala, making it versatile for big data processing.
• Schema Evolution
  Parquet supports schema evolution, allowing changes to the schema without breaking existing data, which helps in maintaining long-lived data pipelines.
• Efficient Read Performance for Aggregations
  Due to its columnar layout, Parquet is highly efficient for processing queries that aggregate data across columns, such as SUM and AVERAGE.

Possible disadvantages

• Write Performance
  Writing data to Parquet can be slower compared to row-based formats, particularly for small inserts or updates, due to the overhead of encoding and compression.
• Complexity in File Management
  Managing and partitioning Parquet files to optimize performance can become complex, particularly as datasets grow in size and complexity.
• Not Ideal for All Workloads
  Workloads that require frequent row-level updates or involve small queries might be less efficient with Parquet due to its columnar nature.
• Learning Curve
  The need to understand the nuances of columnar storage, encoding, and compression can pose a learning curve for teams new to Parquet.
