["Enrico Olivelli (JIRA)" <ji...@apache.org>]

Enrico Olivelli commented on BOOKKEEPER-922:
--------------------------------------------

IMHO it would be better to add support for a generic custom data field. Which may hold a Map<byte[],byte[]> value which could in turn be useful for queries

> We have introduced ctime into ledger metadata through https://issues.apache.org/jira/browse/BOOKKEEPER-879.
> In the same token we would like to introduce createrId also. This can be a 128 bit UUID. Caller can write tools to group ledgers by createrId, in the future we can even enhance this to run queries based on createrId.
