Read-only HTTP-served Zarr store.

Source: R/http_store.R
HttpStore.Rd

Implements the ZarrStore interface over HTTP(S). Used by zarr_daf() when given an http(s):// URL pointing at a .daf.zarr directory served by a static web server. Reads .zmetadata (consolidated metadata) once at open; subsequent store_exists / store_list resolve against the parsed dictionary, and chunk fetches are cached in process memory.

Usage

HttpStore(
  url = character(0),
  zmetadata = list(),
  chunk_cache = new.env(parent = emptyenv())
)

Arguments

url

Root URL of the served Zarr v2 directory.

zmetadata

Parsed consolidated .zmetadata content.

chunk_cache

Environment caching fetched chunk bytes by path.

Details

Writes hard-error: HTTP-served Zarr is read-only.
