Scalable data extraction from data stores

Extraction of data employing a sequence of remote function calls in form of a synchronous multi-batch call chain is provided. Sequencing of calls is enabled by generating parameters associated with the extraction of a next batch of data. The parameterized, dynamic generation of queries allows for optimization of memory utilization by batching result sets and data conversion. Each subsequent call retrieves a packet of data, picking up where the previous call left off without an overlap. Parameters are updated after each call based on extracted data, available memory, and the like.
