Is possile to defragment DRE cache, when some chunks are deleted after DRE synchronization? Is there an automatic defragmentation of DRE cache? Thank you.
The DRE cache doesn't have a utility for defragmentation. The database has been improved and optimized over the life of the product to reduce the necessity for this. For catastrophic failures however, the database/cache can be deleted and repopulated with new traffic if needed.
Hope that helps,
