Streaming Chain Issues

@Chris.Iemma

I can disable the warning log on the console by enabling file logging.

import refinitiv.data as rd
from refinitiv.data.discovery import Chain
config = rd.get_config()
config.set_param("logs.transports.file.enabled", True)
config.set_param("logs.transports.file.name", "refinitiv-data-lib.log")
config.set_param("logs.level", "ERROR")


rd.open_session(app_key='<app key>')


rics = Chain("0#MSFT*.U")
rics.constituents

It takes times to get all chain elements because this method subscribes to real-time chain RICs from Real-Time feed to get all chain elements and there are 3076 chain elements for these chain RICs.

Typically, each chain RIC can provide 14 chain elements. Therefore, it needs to subscribe to around 220 chain RICs to get all chain elements.

The client can try another function, such as rd.discovery.search. For example:

df = rd.discovery.search(
    view=rd.discovery.Views.EQUITY_QUOTES,
    filter="startswith(RIC,'MSFT') and endswith(RIC,'0.U')",
    top=5000,
    select="DocumentTitle, BusinessEntity, RIC, AssetType, AssetState"
)

df
