<p dir="auto">Last month we published an article telling you about some of the upcoming <a href="https://steemit.com/steemit/@steemitdev/upcoming-changes-to-api-steemit-com" target="_blank" rel="nofollow noreferrer noopener" title="This link will take you away from hive.blog" class="external_link">changes to the public API that we host at <code>api.steemit.com. Today we would like to announce one additional item to those set of changes. These changes will all go live as soon as 7 days from now (2019-01-10 16:00:00 UTC). If you are an app developer who relies on <code>api.steemit.com to support your app this can be considered additional time to both review the original set of changes and also to test your apps against these changes.
<p dir="auto"><h3>get_account_votes<p>
<p dir="auto">The <code>get_account_votes method returns all votes made by an account since the beginning of time on the blockchain. For some accounts, this single call can return upwards of 20MB of data. Because of this, <code>get_account_votes is an extremely inefficient way to regularly poll for vote history data and disk-backed instances cannot respond quickly enough to this method. For these reasons we will discontinue support for this method in our public API. In our review of utilization, we found that this method is not used very often and is not required by many apps.
<p dir="auto"><h1>The Replacement<p>
<p dir="auto">For the few apps that do need this type of data, there is a much more efficient way to obtain it. The newer <code>database_api.list_votes method allows you to specify a limit for votes returned and also allows you to start at a particular post. Documentation for this method has been recently added to our developer portal and is <a href="https://developers.steem.io/apidefinitions/#database_api.list_votes" target="_blank" rel="nofollow noreferrer noopener" title="This link will take you away from hive.blog" class="external_link">available here.
<p dir="auto"><h3>Next Steps<p>
<p dir="auto">If you are a Steem app developer who relies on our public API, you should review our <a href="https://steemit.com/steemit/@steemitdev/upcoming-changes-to-api-steemit-com" target="_blank" rel="nofollow noreferrer noopener" title="This link will take you away from hive.blog" class="external_link">previous post about the upcoming API changes and pay special attention to whether you are using the soon-to-be-deprecated <code>get_account_votes method. Our <a href="https://developers.steem.io" target="_blank" rel="nofollow noreferrer noopener" title="This link will take you away from hive.blog" class="external_link">developer portal continues to be an excellent reference and feel free to ask any questions you may have in the comments.

Anybody can answer how this will impact the common users?
Or any practical benefits it may have in the user experience?
~not a coder,just inlove with steem
It shouldn't affect the ordinary user experience at all. Basically we have given developers the ability to be much more specific about what information they pull from the Steem blockchain. Until the changes go through, some developers don't pull any specific information from the blockchain, they just basically take a whole bunch of data and then only use the data they need. But this is a very inefficient process that has contributed to the size of nodes with no real benefit. So we're making extra sure that all developers still have the ability to pull whatever information they need from the blockchain–so their apps don't suffer–while getting rid of the ability to pull so much data all at once for no good reason.
The only meaningful change is that this will help reduce the size and cost of running Steem nodes, which will make it easier for anyone to run their own node, theoretically leading to increased decentralization.
Great work in finding efficiencies. Any estimate of the reduction in RAM requirements for a full node from these changes?

This should be helpful to exchanges as well, no? If steem is expensive for exchanges to make a wallet, gonna be tough to get and keep it listed...
Thanks, anything that will make improvements to the steem under the hood will always be welcome to us.
I really appreciate @andrarchy the way you explain many technical details of the steem blockchain to the masses.
Godspeed.

I really hope it comes to the day that even an ordinary PC can host a Steem private node. Great job in the bearish market guys.
Is there a reason for the blackout in communication from everyone at @steemit?
It would help if at least you could make a public statement @andrarchy.
It would also help if you could discuss the Power Downs by @ned and @steemit.
Otherwise it will look like the @steemit team is abandoning ship, without informing the Steem community about it.
I personally would be happy if @ned is using his funds to start Destiny, a Steem-based Dapp that offers SMT's and equal votes for all of it's users, and is based on verified identities as opposed to anonymous accounts.
i doubt changes to the api impact common users unless the people maintaining their neo-programs don't follow up ... good to see the notice there, thanks @steemitdev
HOW CAN I BLOCK SOMEONE ON DTUBE? WHERE CAN PEOPLE CONTACT SUPPORT TEAM FOR STEEMIT AND DTUBE???
Awesome update!

<p dir="auto">What can be an alternative for this? I haven't made a full Hivemind sync yet (~19M blocks synced). Should I be streaming the blockchain for this?get_account_votesto display posts upvoted by major community accounts such as @curie and @photofeed (https://alpha.1ramp.io/community/curie).Hi!, Did you find an alternative?
For now, I am using account history for the profile and filtering the votes. But this is very inefficient as I need to iterate through a lot of non-vote entries in order to collect a sufficient number of votes.
<p dir="auto">Here's an example using <a href="https://github.com/holgern/beem" target="_blank" rel="noreferrer noopener" title="This link will take you away from hive.blog" class="external_link"><code>beem - <pre><code>from beem.account import Account acc = Account('singhpratyush') for entry in acc.history_reverse(): if entry['type'] == 'vote' and entry['voter'] == acc.name: # Do something with entry <p dir="auto">The entry would look something like this - <pre><code>{'account': 'singhpratyush', 'timestamp': '2019-01-10T15:21:48', 'type': 'vote', '_id': 'c3ebc9b2f2ce5b561d1a6c2873372020ff74e90c', 'author': 'ahmadnayan', 'trx_in_block': 34, 'voter': 'singhpratyush', 'trx_id': '453bdef21336689414e142dbf033e08848679d91', 'block': 29336541, 'op_in_trx': 0, 'weight': 10000, 'permlink': 'n9b6astn4ljaqw00x9lfckegyks65v81o585hg0fqfu01h1a7xw0zvzfpw0ft3hc20190110213037', 'index': 3404, 'virtual_op': 0}Hey, I did use that a lot! It was pretty usefull. 💔
I don't get along with this new method, it seems buggy. So far I've not been able to retrieve the data the same way I used to do. I try to download the votes made by an account when specific authors and permlinks are given but then many votes are missing. When I switch the limit from 30 to 200, for instance, the latest query doesn't include the full data that the first one retrieved. Some votes are missing between them and even some votes actually made by the account are never being retrieved by this method. It reminds me of the
get_postsmethod. I 'm reporting this, otherwise, I need support. 😕Yes, that endpoint is not working as expected. I opened this issue on Github - https://github.com/steemit/steem/issues/3223. It may provide you with some additional information.
Here's a not-so-good method to do it - https://busy.org/steemit/@steemitdev/additional-public-api-change#@singhpratyush/re-mosqueteros-re-singhpratyush-re-steemitdev-additional-public-api-change-20190111t092148496z.
Oh, thanks. I'll take a look.
I cant update my profile image or anything, it always revers back to the previous after saving. Whom to report this issue ?
hey there,
We noticed at the time of rollout of changes (as of Jan 10) that the post's rshares data is now returning undefined
Is this an intended behaviour?
We are for example pulling post data using
steem.api.getDiscussionsByCreatedand then accessing post'spost.vote_rsharesThis is only no longer working on api.steemit.com and api.steemitdev.com
Would be great if you can provide some insights or look into this.
Thanks!
wtf is going on with steem and steemit accounts on twitter ?
they are not working.
