📄️ Data-Time Partitioning
Arc organizes Parquet files by the data's timestamp rather than ingestion time, enabling proper backfill of historical data and optimal query performance.
📄️ Write-Ahead Log (WAL)
Arc's Write-Ahead Log (WAL) provides zero data loss guarantees on system crashes.
📄️ File Compaction
Arc's automatic compaction system merges small Parquet files into larger, optimized files for dramatically faster queries.
📄️ Query Caching
Arc implements multiple caching layers to optimize query performance, particularly for dashboard and monitoring use cases where the same queries are executed repeatedly.
