Reads and, for any non-NULL argument, sets the DAF_PACKED_* / DAF_HTTP_MAX_COALESCE_GAP_KB globals in DataAxesFormats. These control how packed = TRUE storage is chunked, compressed, and cached.

Usage

daf_packed_options(
  compression = NULL,
  compression_level = NULL,
  target_chunk_kb = NULL,
  local_cache_kb = NULL,
  http_cache_kb = NULL,
  http_max_coalesce_gap_kb = NULL
)

Arguments

compression

Compression codec name, e.g. "blosc_zstd_bitshuffle" or "gzip_shuffle" (a Julia Symbol).

compression_level

Integer compression level.

target_chunk_kb

Target chunk size in binary KB.

local_cache_kb

Local decoded-chunk cache size in binary KB.

http_cache_kb

HTTP decoded-chunk cache size in binary KB.

http_max_coalesce_gap_kb

Max gap (binary KB) to coalesce HTTP range reads.

Value

The values in effect before this call, as a named list (visibly when all arguments are NULL, invisibly when setting).
