Zap is set of fast and memory efficient collector data structures that are used during scans to collect results that are categorized into two groups:
- Ephemeral Lifetime Collectors: data collected during a scan, and used during the scan, but not passed back as the results/range of the scan function
- Scan Lifetime Collectors: data collected during a scan and passed back as the part of the results/range of the scan function.
- Cubes
- Shrubs
Because scans are inner loop operations on potentially enormous datasets, collectors are designed to be extremely fast and memory efficient (low GC pressure).
