[EP-tech] Antwort: Re: upgrading IRStats to IRStats2

Dear Matthew,

this is from our last nightly IRStats2 process_stats log, it might give you an estimate of how long a full statistics evaluation would run:

Access: it took 117 secs to parse 5665 records ( average = 48.42 records/sec )
Access: 3071 records kept out of 5665 ( ratio = 54.21% )

I can't comment on your initial question, though. No experience here with IRStats.

(Idea: I would try to compare the irstats2_* and irstats_* database tables on a small test repo to find out whether the old irstats tables could be converted).

Best regards,

Martin

I should also note that our ‘access’ table is multiple jiggle-bytes in size, with hundreds of millions of records, so we’re not overly keen on running a full IRStats regen. We’re currently working on strategies to archive old records from the access table.

Subject: upgrading IRStats to IRStats2
 
Hi folks, sorry if this has been covered elsewhere but I haven’t seen mention of it. One of our repositories was recently updated to 3.3, however we’re still running the old IRStats (v1). We’re eager to update to IRStats2, however we’re not sure what process to go through, nor what risks are involved.
 
Is there any advice on upgrading IRStats to IRStats2?
 
Cheers
