beem is a almost complete python library for steem. It is well tested with 286 unit tests and a coverage of around 77%. The library is now in beta state and its latest version is 0.19.14.

Batch api calls on AppBase

Batch api calls are possible now with AppBase. If you call a Api-Call with add_to_queue=True it is not submitted but stored in rpc_queue. When a call with add_to_queue=False (default setting) is started, the complete queue is sended at once to the node. The result is a list with replies.

from beem import Steem
stm = Steem("https://api.steemitstage.com")
stm.rpc.get_config(add_to_queue=True)
stm.rpc.rpc_queue
[{'method': 'condenser_api.get_config', 'jsonrpc': '2.0', 'params': [], 'id': 6}]
result = stm.rpc.get_block({"block_num":1}, api="block", add_to_queue=False)
len(result)
2

Websocket performance

The websocket performance for getting 24h on Blockchain data could be increased by using threads.
28790 Blocks are fetched from wss://steemd.pieve.science in 18 minutes and 22 seconds.

Using the script from https://github.com/pibara-utopian, 24h Blockchain data could be processed in 11 minutes and 23 seconds. In both cases 16 threads were used.
