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.
