Sijie Guo commented on BOOKKEEPER-879:
--------------------------------------
[~eolivelli] that's cool.
re 1): maybe follow the filesystem standard, calling it 'ctime'.
re 2): you could extend metadata by adding field in LedgerMetadataFormat, which
is protobuf based format. check
bookkeeper-server/src/main/proto/DataFormats.proto
re 3): the encoding is done by UTF_8, no? "new String(.., UTF_8)" and
"getBytes(UTF_8)". Do you know which line doesn't do this? If no, we should fix
it. feel free to create a ticket for that.
> Record ledger creation time
> ---------------------------

> Key: BOOKKEEPER-879
> URL: https://issues.apache.org/jira/browse/BOOKKEEPER-879
> Project: Bookkeeper
> Issue Type: New Feature
> Components: bookkeeper-client, bookkeeper-server
> Affects Versions: 4.3.1
> Reporter: Enrico Olivelli
>
> I think that a creation timestamp would be very useful and it does not cost
> very much. It would be an immutable value.
> Nowadays (on 4.3.1) 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.
> I think that this timestamp should be captured on client while calling
> createLedger or asyncCreateLedger.
> In addition to this very common field maybe it would be useful to add a
> custom byte[] field named "custom client data" in order to let the client
> 'describe' the ledger without the need of extra data on Zookeeper.
