Ivan Kelly updated BOOKKEEPER-49: --------------------------------- Fix Version/s: (was: 4.3.0) > bookkeeper - parallel async read same entry of same ledger will fail > -------------------------------------------------------------------- > > 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: > 0001-BOOKKEEPER-49-bookkeeper-parallel-async-read-same-en.patch > > > 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
