Here it is https://issues.apache.org/jira/browse/BOOKKEEPER-879
Thank you Da: Sijie Guo [mailto:si...@apache.org] Inviato: sabato 7 novembre 2015 01:08 A: user@bookkeeper.apache.org Oggetto: Re: newbie question Enrico, so you are interested in a creation time of a ledger. that sounds a good field to carry on a ledger. I think it could be easily exposed via ledger manager, since a znode already have a creation time I believe. If not, we could think about adding a filed in ledger metadata. Do you mind creating a ticket to ask for this feature? - Sijie On Fri, Nov 6, 2015 at 1:25 PM, Enrico Olivelli <eolive...@gmail.com<mailto:eolive...@gmail.com>> wrote: Hi, honestly I think that a creation timestamp would be very useful and it does not cost very much. It would be an immutable value. Nowadays I must keep that info together with the id of the ledger, for instance in zookeeper, but if that reference gets lost there is now way to know how old a ledger is. -- Enrico Il giorno 20:57 Ven 06/Nov/2015 Sijie Guo <si...@apache.org<mailto:si...@apache.org>> ha scritto: How you manage the ledgers? Do you keep a list of ledgers? Could you delete a ledger when it is out of date? That's probably the easier way to address. As what Flavio pointed out, you might need a high level abstraction over bookkeeper, which manage ledgers, and roll ledgers and delete ledgers when it it out of date. - Sijie On Fri, Nov 6, 2015 at 10:47 AM, Maurício Santiago de Castro <mauricioscas...@hotmail.com<mailto:mauricioscas...@hotmail.com>> wrote: I tried to extend LedgerMetadata, BookKeeper and possibly LedgerHandle to introduce a timestamp to the metadata on handle creation, but I faced package protection problems so I am trying something else. For now I am playing around with it, but I am thinking about using it here<https://github.com/mauricioscastro/basex-lmdb> (https://github.com/mauricioscastro/basex-lmdb) for replicating my key/values one level above the lmdb jni client. Thanks.
