Apply garry's default GDAL configuration for remote COG reads.
garry_gdal_config.RdSets the GDAL config options garry's internal warp readers and
cloud-optimised remote reads want: HTTP multiplexing over HTTP/2,
automatic retries with backoff on transient HTTP errors plus request
timeouts (the cadence odc-stac uses), a capped block cache (GDAL
defaults to 5% of RAM per process, which many daemons would
multiply), single-range COG-header ingest, a skipped directory scan
and a raster-extension vsicurl allowlist for fast remote opens, and
permission to open MEM-driver datasets, which garry's internal warp
readers require. garry_daemons() calls this
on every read daemon automatically; call it yourself for host-side
discovery reads or when you drive mirai::daemons() directly. Each
option is set via set_config_option, so a value you set afterwards
wins.
Details
These are session-global GDAL settings. In particular
GDAL_DISABLE_READDIR_ON_OPEN = EMPTY_DIR speeds remote opens but can
hide sidecars (overviews, world files) for local multi-file reads in
the same session; pass gdal_config = FALSE to garry_daemons() to
skip it.
