Adar Dembo updated KUDU-2615: ----------------------------- Fix Version/s: (was: 1.9.0) > Add more tools for dealing with the WAL > --------------------------------------- > > Key: KUDU-2615 > URL: https://issues.apache.org/jira/browse/KUDU-2615 > Project: Kudu > Issue Type: Improvement > Components: log > Affects Versions: 1.8.0 > Reporter: Will Berkeley > Assignee: Will Berkeley > Priority: Major > > There's only one tool for dealing with WALs, the dump tool, which lets you > see what's in the WAL by reading it like a Kudu server would and then dumping > it as debug strings. > We could probably use a few more, though. This JIRA serves as a tracking JIRA > for new WAL tools and as a parent JIRA for some existing WAL tool JIRAs. > Tools we could add or enhancements we could make: > * 'kudu wal dump --debug' with batch offsets. This would have been useful to > me a couple times when I've done WAL surgery. > * 'kudu wal dump repair' maybe with truncate capability (KUDU-1503) or the > capability to 'punch out' an entry. > * A 'kudu wal compare' tool that can compare two WALs and show their > differences, so the WALs of two replicas of the same tablet could be compared. > * A 'kudu wal edit' tool that can edit some kinds of wal entries-- the use > case for this is editing the hostports of peers in config change operations > (KUDU-2396). -- This message was sent by Atlassian JIRA (v7.6.14#76016)
