There are two methods for retrieving entities and reporting data with the Search Ads 360 Reporting API.
This guide primarily focuses on streaming data from
SearchAds360Service
. Here are high-level distinctions
for the two data retrieval methods:
SearchAds360Service.SearchStream | SearchAds360Service.Search | |
---|---|---|
Suitable for production code | Yes | Yes |
Service | SearchAds360Service |
SearchAds360Service |
Scenario | Fetching objects and reports | Fetching objects and reports |
Response | Stream of SearchAds360Row objects |
Pages of SearchAds360Row objects |
Response's fields | Only those specified in the query | Only those specified in the query |
Daily limits | See API limits and quotas. | See API limits and quotas. |
SearchStream versus Search
While Search
can send multiple paginated
requests to download the entire report,
SearchStream
sends a single request
and initiates a persistent connection with the Search Ads 360 Reporting API regardless of report size.
For SearchStream
, data packets start to download immediately with the entire
result cached in a data buffer. Your code can start reading the buffered data
without having to wait for the entire stream to finish.
By eliminating the round-trip network time required to request each individual
page of a Search
response, depending on your app, SearchStream
can offer
improved performance over paging, especially for bigger reports.
Example
Take a report that consists of 100,000
rows for example. The following
table breaks down the accounting differences between the two methods.
SearchStream | Search | |
---|---|---|
Page size | Not Applicable | 10,000 rows per page |
Number of API requests | 1 request | 10 requests |
Number of API responses | 1 continuous stream | 10 responses |
Performance factors
In general, we recommend SearchStream
over Search
for the following reasons.
For single page reports (under 10,000 rows): No significant performance differences between the two methods.
For multiple page reports:
SearchStream
is typically faster since multiple roundtrips are avoided and reading/writing from disk cache is less of a factor.
Rate limits
Daily limits for both methods adhere to the standard API limits and quotas. A single query or report is counted as one operation regardless of the result being paged or streamed.
