soci-snapshotter Parallel Pull Unpack Mode

SOCI snapshotter Parallel Pull Unpack mode enhances container image pulls by enabling parallel download and unpacking of image layers. For detailed performance tuning guidance, see the SOCI Parallel Mode Performance Tuning documentation in the upstream soci-snapshotter project.

Examples
# Enable SOCI snapshotter
[settings.container-runtime]
snapshotter = "soci"

# Configure SOCI Parallel Pull Unpack settings
[settings.container-runtime-plugins.soci-snapshotter]
pull-mode = "parallel-pull-unpack"

[settings.container-runtime-plugins.soci-snapshotter.parallel-pull-unpack]
max-concurrent-downloads = 10
max-concurrent-downloads-per-image = 5
concurrent-download-chunk-size = "8mb"
max-concurrent-unpacks = 5
max-concurrent-unpacks-per-image = 3
discard-unpacked-layers = true
