    • US East (N. Virginia)
    • EU (London)
  • 3 Load balancers (one per zone)
  • 9 API nodes (3 per load balancer)
  • Traffic policies on geolocation (Asia/North America/Europe/Other)

@Elmato: How did you manage to make websocket connection work with geo-location? To my knowledge websocket doesn't support redirects :-(

@xeroc: as @clockwork mentioned, it DNS level.
This is, depending on the geo-origin of the DNS request we resolve to different load balancers. Then the websocket connection is made and stays on that instance until its closed.

hi, [member=7312]ElMato[/member] [member=6601]wackou[/member] @verbaltech2 could you please check your price feeding and update the script? your feeding price is far below the reasonable figure.

the price from poloniex need to be removed.





Feed prices are back, poloniex was removed from the equation

[member=7312]ElMato[/member] can you check? it seems your feeding price in bitCNY is much higher than the real market price.

It seems that i'm having problems getting prices from btc38/okcoin/huboi

Error fetching book from btc38!
Error fetching ticker from okcoin cn!
Error fetching ticker from huobi!

Great work!!  +5%

Just one question.
Shouldn't we also have a local fork of this two repos?

https://github.com/zaphoyd/websocketpp.git
https://github.com/leutloff/diff-match-patch-cpp-stl

What happen if zaphoyd/leutloff got compromised in any way?

Technical Support / Re: New API for witness_node
« on: December 28, 2016, 01:42:00 am »
Just FYI that Steem has moved on to use a SQL database to store irreversible chain state data. More developer can benefit from using that model, as more people know SQL in comparison to C++.

Paging [member=4854]vikram[/member]
I wonder why it's not clickable. Paging [member=4854]vikram[/member]

//Edit:
It's true that it's not too hard (for me) to implement more API's and/or plugins .. but I don't have time to do it, nor discuss the details, sorry.


[member=18687]abit[/member], how steem will implement the SQL database for the irreversible state?
steemd will be pushing data to the SQL database? or an external process will be polling?

Last time i checked steem source code i didn't see any SQL plugin or something like that.

They will model every object as a table with their corresponding indexes?
Or a plain object_id->text(json) table with custom indexes as tables?

Technical Support / Re: "get_trade_history" API call
« on: December 27, 2016, 08:15:56 am »
Hello there, I'm trying to figure out exactly how to use the 'get_trade_history' database API call. The documentation seems to be a bit off for this one, since the order of the arguments displayed here http://docs.bitshares.org/api/database.html seems to be wrong.

Taking a look at the graphene code itself, I can find at /libraries/app/database_api.cpp:110 the following:

Code: [Select]
vector<market_trade> get_trade_history( const string& base, const string& quote, fc::time_point_sec start, fc::time_point_sec stop, unsigned limit = 100 )const;
But this is kind of at odds with what I actually find when querying the API, since it seems to be expecting a date format.

Connecting directly to a via wscat I get the following:

Code: [Select]
> {"id":1,"method":"call","params":[0,"get_trade_history",["BTS","EUR","20161215T0130000","20161212T233000", 100]],"jsonrpc":"2.0"}
< {"id":1,"result":[]}

And no, reverting the start and stop values doesn't seem to change anything either. Same result. Can anyone give me a hand with this?

I wrote a post to see if we can join efforts in upgrading the API of the witness_node or build a parallel solution to query the blockchain state in any possible way.
