-----------------------------------
Summary: Relax durability
Key: BOOKKEEPER-934
URL: https://issues.apache.org/jira/browse/BOOKKEEPER-934
Project: Bookkeeper
Issue Type: Improvement
Reporter: Jia Zhai
Assignee: Jia Zhai
I am thinking adding a new flag to bookkeeper#addEntry(..., Boolean sync). So
the application can control whether to sync or not for individual entries.
- On the write protocol, adding a flag to indicate whether this write should
sync to disk or not.
- On the bookie side, if the addEntry request is sync, going through original
pipeline. If the addEntry disables sync, complete the add callbacks after
writing to the journal file and before flushing journal.
- Those add entries (disabled syncs) will be flushed to disks with subsequent
sync add entries.
There is already a discussion in mail thread, here this ticket could gather
ideas, and provide the discussion materials
