ecs-sync v1.4
https://community.emc.com/docs/DOC-38905
- changed project name to ecs-sync
- fixed SDK-116 (memory leak in CAS plugins when many clips fail)
- added docker support via config and scripts inside the docker/ folder of the distribution
- S3Source: when migrating the root of a bucket, now uses flat enumeration instead of crawling the prefixes (which is not necessary in this case)
- reduced source_id column in tracking table and reverted back to a primary key for performance
- other minor bug fixes
