The SearchMetrics source supports both Full Refresh and Incremental syncs. You can choose if this connector will copy only the new or updated data, or all rows in the tables and columns you set up for replication, every time a sync is run.
If there are more endpoints you'd like Airbyte to support, please create an issue.
Full Refresh Sync
Incremental - Append Sync
The SearchMetrics connector should not run into SearchMetrics API limitations under normal usage. Please create an issue if you see any rate limit issues that are not automatically retried successfully.
