Okay to purge trace table?
Greetings all,
We have a million entries in the trace table in one of our Accumulo
clusters and a million and a half in another. We haven't manually enabled
any tracing activities, and in looking at the entries, they seem to be
generated by Accumulo does on its own (compact, wal, getFileStatus,
minorCompactionStarted, minorCompaction, prep, commit, etc).
Does Accumulo maintain this table or do I / should I manually purge it from
time to time? If it's on us to maintain it, are there any guidelines or a
procedure for doing so?
Thanks in advance,
Terry

I added a ticket for it not being in the user manual under the 1.6
documentation umbrella ticket.

For what it's worth, you can disable the tracing altogether by leaving the 'tracers' file blank.

Does it make sense to create a JIRA ticket asking for an age-off iterator
to be the default on the trace table? Maybe set for something like two
weeks? If we don't add a default age-off iterator, where should the
documentation be changed to talk about this topic? Does the user manual
talk about the trace table?

Thanks Eric. Given my newness to Accumulo I just wanted to ensure I didn't
break anything by purging it.
I'll look at setting an age-off filter on it to avoid having to manage it
manually.
Thanks!

You could put an age-off iterator on it, or just purge it from time-to-time.
I probably should have configured the trace table with an age-off filter by
default. But for now, you need to manually manage the data.
You can use delete rows to wipe the table efficiently:
