Client to bundle configuration needed for API requests.
project
Optional[str]
Project ID for the project which the client acts on behalf of. Will be passed when creating a dataset / job. If not passed, falls back to the default inferred from the environment.
credentials
Optional[google.auth.credentials.Credentials]
The OAuth2 Credentials to use for this client. If not passed (and if no _http
object is passed), falls back to the default inferred from the environment.
_http
Optional[requests.Session]
HTTP object to make requests. Can be any object that defines request()
with the same interface as requests.Session.request
. If not passed, an _http
object is created that is bound to the credentials
for the current object. This parameter should be considered private, and could change in the future.
location
Optional[str]
Default location for jobs / datasets / tables.
default_query_job_config
Optional[ google.cloud.bigquery.job.QueryJobConfig
]
Default QueryJobConfig
. Will be merged into job configs passed into the query
method.
default_load_job_config
Optional[ google.cloud.bigquery.job.LoadJobConfig
]
Default LoadJobConfig
. Will be merged into job configs passed into the load_table_*
methods.
client_info
Optional[google.api_core.client_info.ClientInfo]
The client info used to send a user-agent string along with API requests. If None
, then default info will be used. Generally, you only need to set this if you're developing your own library or partner tool.
client_options
Optional[Union[google.api_core.client_options.ClientOptions, Dict]]
Client options used to set user options on the client. API Endpoint should be set through client_options.
default_job_creation_mode
Optional[str]
Sets the default job creation mode used by query methods such as query_and_wait(). For lightweight queries, JOB_CREATION_OPTIONAL is generally recommended.
