In #5838 and #6209 we switched to a new shard key mapping format on disk. This was necessary for compatibility with numeric keys.

Support for the old format was kept to allow forward/backward compatibility. Qdrant 1.14 forces the new format and migrates the file if needed. The plan was to remove support for the old format in Qdrant 1.15.

This now removes the old format. The change will land in 1.16.0.

Tasks

• Release Mirgate from old shard key format on load #7110 in a previous minor version first! (1.15.4)
• Bump storage compatibility files, only use new shard key format
• Merge before 1.16.0 release
