In the previous implementation of the metabase, the unique value of the header was assigned a bucket, the elements of which were leaves with a key-address and an empty value. This approach was relatively efficient in terms of write speed. However, a large number of buckets led to a rapid increase in the database volume (~4GB for 100K objects with unique attributes). An approach is presented with storing indexes on the value of headers in the leaves of the tree, where the keys are the unique values of the header, and the values are a serialized list of addresses (gob encoding is temporarily used for serialization). The new approach gave a good result in saving space (~350MB), however, it significantly reduced the write speed with an increase in the number of objects (~ 80x after 100K objects).
