Introduction

Incremental data collection is a data collection method used to update and maintain existing data to reflect the latest changes in a data source. This method differs from a full collection, which captures all data from the beginning, whereas an incremental collection captures only the changes that have occurred since the last collection.

Applicable Scene

Incremental data collection is suitable for scenarios that require real-time or near real-time data synchronization, such as financial transactions or social media updates. Compared to full collection, incremental collection reduces the bandwidth required to send data, reducing storage costs. For applications that require regularly updated data, incremental collection can reduce data retrieval time and resource costs.

Pros: Incremental data collection reduces the amount of data sent and speeds up collection and transmission times. Data can also reflect changes in near real-time while reducing bandwidth and storage costs.

Cons: Incremental retrieval requires an initial full retrieval, which can result in longer delays. You must also monitor data source changes and efficiently implement incremental retrieval processes that may require additional programming and configuration.
