Examples with Data org.h2.store.Data used on opensource projects

Example 11 with Data

use of org.h2.store.Data in project jackrabbit-oak by apache.

the class BlobCache method addGeneration.

@Override

        // if we switch the data first,
        // we could end up with the data in store 1
        // but the metadata in store 2 - which could
        // result in a data block not found if store 1
        // is removed later on
