Interface ConnectorHints

Backend characteristics that tune how the pipeline issues reads.

interface ConnectorHints {
coalesceGap?: number;
prefetch?: number;
}

coalesceGap?: number

Byte ranges separated by at most this many bytes are merged into one read. Large for high-latency backends (HTTP, S3), small for local disk.

prefetch?: number

Size of the first read of a file. It covers the header and, because the index follows the header root-first, the top levels of the spatial index.
