> Key: BOOKKEEPER-1055
> URL: https://issues.apache.org/jira/browse/BOOKKEEPER-1055
> Project: Bookkeeper
> Issue Type: Improvement
> Reporter: Matteo Merli
> Assignee: Matteo Merli
> Priority: Minor
> Fix For: 4.5.0
>
>
> On each request client and bookies are exchanging the ledger masterKey, which
> is a 20 bytes MAC digest of the ledger password.
> For each request there is a considerable overhead in allocating byte arrays
> when parsing the add/read requests.
> If the client is a passing an empty password, we should optimize the data
> path to skip all allocations (related to the masterKey) and instead rely on a
> static byte array.
