Configuration
The Client API library constructor supports a number of options that can be provided as part of the optional 'opts' hash map to these methods:
-
initialize
(apikey, opts={}) (constructor) -
Client.authenticate
(user, password, opts={}) (class method) -
Client.server_status
(opts={}) (class method)
Endpoint
Add the :endpoint
key to the opts to provide an alternative endpoint to make
the API calls to. Examples are an alternate API endpoint or a static IP address
provided by Treasure Data on a case-by-case basis.
The default endpoint is:
https://api.treasuredata.com
and configure communication using SSL encryption over HTTPS; the same happens every time the provided endpoint is prefixed by 'https'.
E.g.
opts.merge({:endpoint => "https://api-alternate.treasuredata.com"})
The endpoint can alternatively be provided by setting the TD_API_SERVER
environment variable. The :endpoint
option takes precedence over the
TD_API_SERVER
environment variable setting.
For communication through a Proxy, please see the Proxy option below.
Connection, Read, and Send Timeouts
The connection, read, and send timeouts can be provided via the
:connect_timeout
, :read_timeout
, :send_timeout
keys respectively.
The values for these keys is the number of seconds.
E.g.
opts.merge({:connect_timeout => 60,
:read_timeout => 60,
:send_timeout => 60})
SSL
The :ssl
key specifies whether SSL communication ought to be used when
communicating with the default or custom endpoint.
This option is ignored if the endpoint (default or custom) URL specifies the scheme (e.g. the protocol, https or http) in which case SSL enabled/disabled is inferred directly from the URL scheme.
E.g.
# SSL is enabled as specified by the :ssl option
opts.merge({:endpoint => "api.treasuredata.com", :ssl => true})
# the ssl option is ignored in this case
opts.merge({:endpoint => "https://api.treasuredata.com", :ssl => false})
# You can disable verification
opts.merge({:endpoint => "https://api.treasuredata.com", :verify => false})
# You can use your own certificate
opts.merge({:endpoint => "https://api.treasuredata.com", :verify => "/path/to/cert"})
Proxy
If your network requires accessing our endpoint through a proxy (anonymous or
private), the proxy settings can be specified through the :http_proxy
option.
E.g.
# anonymous proxies
opts.merge({:http_proxy => "http://myproxy.com:1234"})
opts.merge({:http_proxy => "myproxy.com:1234"})
# private proxies
opts.merge({:http_proxy => "https://username:password@myproxy.com:1234"})
opts.merge({:http_proxy => "username:password@myproxy.com:1234"})
The proxy settings can alternatively be provided by setting the HTTP_PROXY
environment variable. The :http_proxy
option takes precedence over the
HTTP_PROXY
environment variable setting.
Additional Header(s)
The Ruby client configures the communication with the Treasure Data REST API endpoints using the required HTTP Headers (including authorization, Date, User-Agent and Accept-Encoding, Content-Length, Content-Encoding where applicable) basing on what method call is made.
The user can specify any additional HTTP Header using the :headers
option.
E.g.
opts.merge({:headers => "MyHeader: myheadervalue;"})
To specify a custom User-Agent please see the option below.
Additional User-Agent(s)
Add the :user_agent
key to the opts hash to provide an additional user agent
for all the interactions with the APIs.
The provided user agent string will be added to this default client library user
agent TD-Client-Ruby: X.Y.Z
where X.Y.Z is the version number of this Ruby
Client library.
E.g.
opts.merge({:user_agent => "MyApp: A.B.C"})
which sets the user agent to:
"MyApp: A.B.C; TD-Client-Ruby: X.Y.Z"
Retry POST Requests
Add the :retry_post_requests
key to the opts hash to require that every
failed POST request is retried for up to 10 minutes with an exponentially
doubling backoff window just as it happens for GET requests by default.
Note that this can lead to unwanted results since POST request as not always idempotent, that is retrying a POST request by lead to the creation of duplicated resources, such as the submission of 2 identical jobs on failures.
As for GET requests, the retrying mechanism is triggered on 500+ HTTP error codes or the raising of exceptions during the communication with the remote server.
E.g.
opts.merge({:retry_post_requests => true})
to enable retrying for POST requests.
Testing Hooks
The client library implements several hooks to enable/disable/trigger special behaviors. These hooks are triggered using environment variables:
-
Enable debugging mode:
$ TD_CLIENT_DEBUG=1
Currently debugging mode consists of:
- show request and response of
HTTP
/HTTPS
GET
REST API calls; - show request of
HTTP
/HTTPS
POST
/PUT
REST API calls.
- show request and response of
