We closed a few of them as Won’t Fix. But the issues that were crippling were - There is no way to replay an orphaned log and together with https://issues.apache.org/jira/browse/TS-2629 https://issues.apache.org/jira/browse/TS-2062 https://issues.apache.org/jira/browse/TS-2101 https://issues.apache.org/jira/browse/TS-2781 https://issues.apache.org/jira/browse/TS-910 this becomes completely crippling (it filled up our disks). > > the current ATS logging a ugly but very good in performance thinking log > system, the SAC is a dedicated commercial server to offer log collation > service, due to that we are now open sourced, that is a good idea removing > the duplicated SAC codes.

No one has said anything about the logging infrastructure itself. In fact, I do not think it’s ugly, I think it’s very good. This has nothing to do with that, logging will work as it does. > > yes, logging has some ugly bugs, but collation should not that bad after > Yunkai’s work, and it does not bother you if you just logging to local disk > and collection with the other systems, right? Yes, it did bother us, because the misbehavior around orphaned logs are crippling. > > please consider keep this feature, I am very happy that a simple collation > works for me out of box. > > sure you may find someone will take interest in supporting it, only if it is > still there. So, I take it that 1) You use this feature? 2) You will support this feature, and work on the code? I could probably be convinced to give this feature another year “probation”, but only under the conditions that you answered “yes” to both questions above. If so, I’ll file a Jira on the biggest issue, that orphaned logs are abandoned with no way to get inserted again. Anyone else have any thoughts on this? — Leif
