Limits: Benefits shrink for compute/write-heavy workloads and depend on useful prefetch distance and batching concurrency. CoroBase expresses each transaction as a coroutine and interleaves transactions to batch memory accesses and issue software prefetches while retaining the transaction API.

Language/runtime continuations can hide latency while preserving readable transactional control flow. CoroBase: Coroutine-Oriented Main-Memory Database Engine workloads=read-intensive and mixed OLTP on a 48-core server; baselines=conventional main-memory execution; metrics=transaction throughput; scalability; results=close to 2x on read-intensive workloads Can main-memory OLTP hide pointer-chasing stalls without rewriting the database around manual continuations? lab Use coroutines to interleave independent requests around predictable long-latency accesses.

Question: Can main-memory OLTP hide pointer-chasing stalls without rewriting the database around manual continuations? Context: Modern in-memory engines are often memory-latency bound, but conventional batching complicates transaction code. Method: CoroBase expresses each transaction as a coroutine and interleaves transactions to batch memory accesses and issue software prefetches while retaining the transaction API. Evaluation: workloads=read-intensive and mixed OLTP on a 48-core server; baselines=conventional main-memory execution; metrics=transaction throughput; scalability; results=close to 2x on read-intensive workloads Interpretation: Language/runtime continuations can hide latency while preserving readable transactional control flow. Reusable lesson: Use coroutines to interleave independent requests around predictable long-latency accesses. Applicability: Main-memory databases with pointer-heavy read paths. Limits: Benefits shrink for compute/write-heavy workloads and depend on useful prefetch distance and batching concurrency. not_recorded corobase coroutine oriented main memory database engine c4a28018# d97b2ca3bf2576fa7b8632a40b56332b 3000 canonical-paper-v2-c4a28018 2026-07-18T05:15:33Z 2461239.7191319 S3ResearchAgent Yongjun He et al., "CoroBase: Coroutine-Oriented Main-Memory Database Engine", PVLDB 2021. paper Verification: full_text; confidence=high.
