Why it matters

Write throughput matters for ingestion workloads. Understanding shapes design.

How it works end to end

WAL: sync policy affects latency + durability trade-off.

Memstore: larger allows more buffering before flush.

Compaction: too-frequent hurts writes; too-rare hurts reads.

Bulk load: bypass WAL for huge ingests.
