Apache Parquet VS Second Computer

• 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.

• Enhanced Focus
  Second Computer provides a dedicated device, minimizing distractions compared to multitasking on a single computer.
• Improved Productivity
  By separating tasks across two devices, users can maintain workflow organization and potentially increase productivity.
• Simplified Workflow
  Having a second computer allows for a more streamlined workflow where users can dedicate each device to specific tasks.
• Backup Solution
  A second computer acts as a backup system, ensuring users can continue working if one device encounters issues.

Possible disadvantages

• Increased Costs
  Purchasing and maintaining a second computer can be costly, involving expenses for hardware, software, and potential repairs.
• Complex Setup
  Setting up and managing two computers can be complex, requiring time and effort to configure and synchronize data across devices.
• Space Requirements
  Having an additional computer may require more physical space, which can be a constraint in small work environments.
• Maintenance Challenges
  With two computers, there are increased maintenance demands, including software updates and hardware upkeep for both devices.

• Can you build observability ingestion on S3 alone — no Kafka, no disks, no coordination layer?

  Apache Iceberg fits these requirements well. Iceberg stores data as immutable Apache Parquet files and adds them through atomic commits, so readers always see a consistent snapshot. A separate metadata layer prunes files by their... - Source: dev.to / 3 months ago

  Depends on the domain. There's a bunch of sciences using large datasets served up efficiently using static file formats, e.g., https://zarr.dev/ and https://parquet.apache.org/. - Source: Hacker News / 3 months ago

• What Are Table Formats and Why Were They Needed?

  The data files themselves are still standard Parquet or ORC. The table format adds a metadata layer on top that gives those files the properties of a database table. - Source: dev.to / 5 months ago
