Model cache on Ponos agents
| This only affects the Enterprise Edition of Arkindex. |
Ponos agents will now download model versions in a models directory under data_dir. This allows each model version to be re-used in multiple tasks, which reduces bandwidth and disk space usage. Tasks can start quicker, especially when running a process with multiple chunks.
A new ARKINDEX_MODEL_DIR environment variable is provided to each task to specify the path to the model version. The previous undocumented download path of $PONOS_DATA/extra_files/model is still available, but it may be removed in future releases. Arkindex workers should be updated to use ARKINDEX_MODEL_DIR instead.
There is no automatic cleanup of the models directory. Instance administrators may safely delete it when no tasks are currently running.
The integrity of downloaded model versions can only be verified once they are first downloaded. When the directory for one model version already exists under models, it will be re-used without re-downloading and without any integrity checks. To force a re-download, delete the parent directory entirely.
