Cosmo Update Asset Size and Date

The Cosmo Update Asset Size and Date Action node updates the file size and modification date of an asset in the Cosmo database.

The node reads the actual media file from the storage system and compares its properties with the database values (filesize and lastModified). If differences are detected, the database entries are updated accordingly.

All database entries referencing the same file path are updated simultaneously.

This node is especially useful for workflows involving dynamically growing or modified files.

Input Parameters

Asset Path Full file path of the asset whose information should be updated.

The asset lookup is performed using the Unix path representation. Ensure that path mappings and stored paths in the database are consistent.

Behavior

  • Reads the file size and modification date directly from the file system

  • Updates the filesize and lastModified fields in the Cosmo database

  • Updates all asset instances referencing the same path

  • Does not modify the media file itself

  • Supports asynchronous execution

hashtag
Typical Use Cases

  • growing recording files (e.g., ongoing capture or ingest)

  • restored media from backup

  • file replacement with newer media

  • storage migration or manual copy operations

  • verification workflows after transfers

hashtag
Benefits

  • keeps database information consistent with real storage

  • prevents incorrect online/offline or outdated file states

  • avoids manual database maintenance

  • improves reliability of downstream workflows

Practical Note

Cosmo normally trusts the information stored in its database. This node is the way to tell Cosmo: “Check the disk again — the file has changed.”

Without running this node, Cosmo may still display outdated size or date information even though the media file itself has been modified.
