Migrate objects metadata from StreamMeta to StreamInfo #46

Open mniewrzal opened 2 years ago

mniewrzal commented 2 years ago

After metainfo refactoring metadata column from objects table is storing marshaled StreamMeta which contains StreamInfo. StreamMeta is duplicating data that we have directly in objects table so we need to do live migration and:

go over all objects in DB
unmarshal Metadata to StreamMeta and get StreamInfo
Update Metadata with only StreamInfo
Migrated from https://storjlabs.atlassian.net/browse/PG-201

It looks that we can save ~70 bytes per object.

We need to remember that StreamMeta contains metadata key and nonce and its also need to be migrated to table column.
