Firestore Increment - Counters that Scale

[stockiten]

firestore increment is 100% what I need currently for my project !!!! Thanks for sharing mate

Maaaan, that count animation at 0:45 is dope!!

[troythompson]

Right on time Jeff. Firebase should be paying you

I am so happy to have this, I can now pull out the functions code that I am using to do my inc/dec functions! Please more videos like this!!!!

[bioburden]

Wow, that's nice that it now reduces the need for a cloud function. Awesome stuff!

[DSodienye]

Awesome. I have been waiting for this feature for ages. Kudos Jeff. Thanks firebase for updating your SDK.

[rodyguzman]

Nice feature but, what would prevent an user to modify the aggregation value if you put that logic in the client? I can't think of a rule to prevent that (considering that the aggregation value is variable)

[patrickmullot]

Another cool video from Jeff! Nicely done!

[Methodician]

Yes to more quick video! This fit into my wait at the but stop. Also: increment is an awesome update! Thanks for keeping us informed.

[alexbackflip]

Is sharding (distributed counters) still needed with this method if dealing with frequent updates? Or is there some added backend technology to support additional increment/decrement updates?

behind jef there is a team is obliged !! it's not possible to make tutorials as beautiful

I've come to the conclusion that the best way to do counting is to forego firestore and just use the realtime database for your counter data. Which ensures that you always have a 100% accurate number in the counter.

Even if you don't need a 100% accurate counter, it also means the code is much simpler

[harpymaslow]

You rock ! Thx Jeff. I've moved all my aggregated datas (counters and stuff) to RTDB because of that

[matthiasgehrmann]

nice tip, thank you very much. and yes, this kind of 'quick tip video' is a great format and i would love to see more of these in the future :)

[hooligansofts]

Now thats a great feature and a good video as always! One quick question tho
Should we use it in a cloud function or in the frontend, as I guess it may be possible for the client to manipulate the increment value on the frontend.

[narcodico]

Finally they made this possible. Now they should definitely make something like multiple array-contains possible in a query. Does a solution even exist for this kind of requirement ?

[nepalesecreator]

Man excatly the same problems that i had in mind !! Each and every is solved thenks !!!

Normally if I’m doing a count, I just save each individual increment or decrement in the database and add it. Normally it’s pretty quick up to a few million rows. I use that method when information needs to be stored with the Increment as well. For example, IPaddress

This is going to be a big help! Thanks for giving us the nuts and bolts to get going with it :)

Are there any concurrent write issues with fieldvalue.increment? If you send increments in batches from multiple clients at the same time to the same document, will it fail to update correctly? I find my own counts are off occasionally (very rarely, but sometimes).
