You use the purge command to remove the unwanted indexes. Trillium uses indexes for many purposes. For example:

  • List views create a temporary index when displayed.

  • The join engine uses indexes extensively.

  • av2t indexes are used to speed-up drill downs to rows.

Most of these indexes result in files with an extension of .ndx and .nta. The indexes are automatically deleted when the task with which they are associated is complete and:

  • When a user logs out, all of the temporary indexes are deleted.

  • Join indexes are deleted when the joins job is complete.

  • The av2t indexes generally remain for as long as the entity remains.

However, there are times when an index is left behind (for example, if you kill a process before it completes).
