Superseded by #73790 (stacked on #62922). There, `LazyXComSequence` itself reads in chunks through `GetXComSequenceSlice`, for indexing, iteration and the async reads alike, with its own `[core] xcom_sequence_chunk_size` option (default 32) and at most one chunk held in memory. That also answers the open question here, about a prefetch size fixed to `core.parallelism` being too static. -- This is an automated message from the Apache Git Service.
