Tuning performance
Learn how to plan the infrastructure of BigFix Inventory and to configure the application server to achieve optimal performance. The following guidelines are applicable in big data environments as well as in smaller environments that are running on low-performance hardware.
REST API considerations
You can use BigFix Inventory REST API to retrieve large amounts of data that is related to computer systems, software instances, and license usage in your environment. Such information can then be passed to other applications for further processing and analysis.
Optimizing response time
Starting from 10.0.2, BigFix Inventory uses HTTP streaming for JSON responses. As a result, pagination can be omitted and the whole dataset can be fetched using a single query. The pagination feature is still available and can be used. When using the pagination feature, it is recommended to retrieve the total number of records only once and then iterate over pages.

  - Options to limit size of the individual response
    Starting from 10.0.2, BigFix Inventory uses HTTP streaming in JSON responses. In HTTP response method, the HTTP Header Transfer Encoding is set to chunked and the response size is not determined. As a result, the data is available in stream as the database provides records that matches the API. With this improvement, pagination in the API is optional and all data can be fetched with a single query.

Avoiding calculation of the number of records returned

When executing an API call, use countSwitch=1 attribute to avoid calculating number of reported rows. To return total number of the rows for an API query, use countSwitch=2 and then retrieve pages of the records.

Retrieve total number of available records.

https://hostname:port/api/sam/raw_file_facts?token=token&countSwitch=2

Retrieve first 10000 records by using the limit parameter.

https://hostname:port/api/sam/raw_file_facts?token=token&countSwitch=1&limit=10000&offset=0

Retrieve next 10000 records. You can ignore the already retrieved records by using the offset parameter.
```
https://hostname:port/api/sam/raw_file_facts?token=token&countSwitch=1&limit=10000&offset=10000
```
