Optimizing solution -
Previously, due to copying the entire DATABASE during a begin(), the memory usage was getting doubled which was in-efficient.
To optimize, this change introduces two maps -
deletedKey
anddeletedValue
which keep track of deleted keys and corresponding occurrences ofupserted keys
in the current transaction.get()
- now recursively searches for the key till root nodeset()
- Before set a value, check with get() if the value exists and then handle the upsert.commit()
- Deep merges each map as we go up till the root node.
