Abstract
According to certain aspects, a computer system may be configured to obtain information indicating a plurality of groupings of data of a data source, the information indicating a number of data items included in each of the plurality of groupings; determine a first grouping of the plurality of groupings including one or more data items that have changed by comparing a first number of data items included in the first grouping and a historical number of data items included in each of the plurality of groupings; access data items included in the first grouping from the data source; compare the data items included in the first grouping to data items of a corresponding compressed local version of the first grouping of data items; extract changed data items of the first grouping; and forward the extracted changed data items to a destination system.
