Archiving and restoration of distributed database log records

A record archiving method, comprising:

• receiving a request to generate an archive of a record stored by a distributed database;
• in response to the request to generate an archive of the record, archiving the record based at least in part on one or more operations performed using a degree of parallelism in accordance with a concurrency parameter and a hash function applied to at least a portion of the record, wherein the record is archived with information indicative of a stored position of the record in a hierarchy of storage entities of the distributed database;
• obtaining a request to retrieve the archived record;
• in response to the request to retrieve the archived record, applying the hash function to the portion of the archived record to generate a hash value;
• identifying a storage entity to obtain the archived record based on the hash value;
• retrieving the archived record;
• and
• storing the retrieved archived record on the storage entity.

A record replay method for a distributed database, the method comprising:

• obtaining a request to replay a plurality of records stored in an archive associated with computer storage;
• in response to the request, mapping a record of the plurality of records to a shard of a distributed database at least based on a mapping mechanism associated with the record and a hash function applied to at least a portion of the record, the shard of the distributed database selected based at least in part on applying the hash function to at least the portion of the record to generate a hash value used to identify the shard of the distributed database, and wherein the mapping mechanism is defined at least based on a level of concurrency;
• and
• storing the record in the shard.
