Latest Patents

One of Ji Hoon Jang's latest patents is titled "Change-aware snapshot replication." This invention provides techniques and solutions for improved snapshot replication. Typically, an initial replica obtained using snapshot replication is periodically updated. However, the update process can unnecessarily consume computing resources if data in a source data object has not changed with respect to data in a replica data object. The disclosed techniques check to determine whether a snapshot replica is out of date before obtaining a new snapshot. These checks can be performed on manual request or triggered by events, such as receiving a query that accesses the replica data object or according to a schedule. Information for current and prior versions of the remote data object can be compared to determine whether a replica is out of date, such as digest values of contents of the remote data object or timestamps associated with the remote data object.

Another notable patent is "Native multi-tenant row table encryption." This invention includes systems and methods for determining a first encryption key associated with a data page of a row store database table stored in volatile memory. The process involves encrypting the body of the data page using the first encryption key and storing an encrypted data page comprising the header and the encrypted body in a persistent storage system.
