Migration from Berkeley DB to Leveldb in Ethereum
In 2013, a new version of Bitcoin Core was launched, which introduced several improvements, including Berkeley DB migration to Leveldb. At that time, migration was seen as an opportunity to update our storage mechanism and improve general performance.
According to the launch notes from Bitcoin.org, Leveldb is a fast, open-source store, in memory, which offers excellent scalability and reliability. Unlike traditional databases such as Berkeley DB, who use disk for operations, LeveldB stores data in memory, which makes it much faster and more efficient.
Why choose Leveldb?
Then why did we decide to migrate from Berkeley DB? Here are some reasons:
* Performance : As mentioned above, Leveldb is significantly faster than traditional databases such as Berkeley DB. This means that our network can manage increased transactions volumes without having performance problems.
* Scalability : Leveldb’s memory storage mechanism facilitates the expansion of the database as multiple knots join the network. We did not want to introduce any complexity or new addictions to slow down our adoption.
* Security : By removing a disk-based storage solution, we can ensure that our data is encrypted at rest and in transit, providing an additional layer of security.
Implementation
To migrate from Berkeley DB to Leveldb, we have implemented the following changes:
- We replaced Berkeley DB backdly with Leveldb database.
- I have updated the
DB.Cfile to use the new LeveldB interface.
- We have changed the
blockchain.HHa to use the new LeveldB configuration.
Benefits
Migration had a positive impact on our network:
* Improved performance
: Increased speed of data access and storage is visible in our test environments.
* Increased scalability : Migration away from Berkeley DB, we managed to manage more transactions without experiencing performance problems.
* Improved security : Our data encrypted and transit data provide an additional layer of protection against potential threats.
In conclusion, the migration from Berkeley DB to Leveldb was a successful movement. We are sure that this change will continue to benefit from our network as we expand and grow.
