2.10.9
Features
EFS Volume support for @batch
This release adds support for mounting existing EFS volumes with @batch
Usage
You can specify one or multiple volumes to be mounted with the batch decorators efs_volumes= attribute. The volumes will be mounted under /mnt/volume-name by default, but you can also specify a custom mount point separated by a semicolon with the volume.
Examples
@batch(efs_volumes="fs-001")
@step
...
@batch(efs_volumes=["fs-002", "fs-003"])
@step
...
@batch(efs_volumes="fs-003:/mnt/custom-mountpoint"])
@stepSupport custom mount point for host volumes with @batch
This release also adds support for custom mount points for host volumes with @batch.
Example
@batch(host_volumes="/home:/mnt/host-homedir")
@stepImprovements
@conda and @pypi changes
@pypi can now handle dependencies with special characters in versions
Fixes a @conda bug where environments were not appending to PATH during runtime if the decorator was applied implicitly to the step. This bug affected dependencies that install a binary, causing them to not be found during runtime due to the environment missing from the PATH.
Decorator lifecycle improvement
Previously the lifecycle methods task_pre_step and task_decorate were being called consecutively on a per-decorator basis. This release changes the lifecycle so that task_pre_step is called on all decorators before any task_decorate is called.
Better checking of datastore dependencies
This release improves the way that datastore dependencies are checked, in order to avoid an issue where previously run metadata could be published to the metadata service, but the execution fails to start due to missing dependencies for pushing data to the datastore.
