Re^2: HoA create from array using map, more efficient?

Thanks BrowserUK, will try the alternate construction method...

>> Is that really a possibility?

Yes, sure, if other team members on the platform create snapshots and volumes during operations, by some other method (not my scripting), and use different/partial tags or none at all..

If you're calling me paranoid, I'll take that as a compliment :):)

If you're calling me paranoid I'd place your knowledge of the possibility that "Yes, sure, if other team members ... create snapshots by some other method" under the same category as "actual experience, or documentation", so no, you're not paranoid. Though I'd have to suggest that it might be better to ensure, (mandate; by providing a library to generate the tags), that they do not use some other method, than to look for work-arounds for the possibility that they do. If they do not include a timestamp, how are you going to "decide which objects are old enough to delete"? Using defensive programming to handle the possibility in production -- and paying the inevitable costs for doing so, which on a platform where you are paying directly for cpu usage directly affects your bottom line -- is a poor substitute for weeding out such errors(), during pre-production testing. (if you mandate the tag format, non-compliance becomes an error.) Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error. "Science is about questioning the status quo. Questioning authority". In the absence of evidence, opinion is indistinguishable from prejudice.	[reply]
