> --------------------------------------------------------------------

> Key: BOOKKEEPER-49
> URL: https://issues.apache.org/jira/browse/BOOKKEEPER-49
> Project: Bookkeeper
> Issue Type: Bug
> Components: bookkeeper-client
> Affects Versions: 4.0.0, 4.1.0
> Reporter: Sijie Guo
> Assignee: Sijie Guo
> Attachments:

>
> all ledgers shared a PerChannelBookieClient.
> PerChannelBookieClient put all the read requests in a
> ConcurrentHashMap<CompletionKey, ReadCompletion> map called readCompletions,
> which is indexed by CompletionKey. If two read requests have same entryId and
> same ledgerId, they have the same CompletionKey, the latter one will
> overwrite the previous one. So a read request's callback will not be invoked.
> we may need to chain the callbacks for same completion keys.
