In order to ingest data from an arbitrary source in a set of sources, a computer system accesses predefined configuration instructions. Then, the computer system generates a dynamic data-ingestion pipeline that is compatible with a Hadoop file system based on the predefined configuration instructions. This dynamic data-ingestion pipeline includes a modular arrangement of operators from a set of operators that includes: an extraction operator for extracting the data of interest from the source, a converter operator for transforming the data, and a quality-checker operator for checking the transformed data. Moreover, the computer system receives the data from the source. Next, the computer system processes the data using the dynamic data-ingestion pipeline as the data is received without storing the data in memory for the purpose of subsequent ingestion processing.

Computer systems and methods for estimating the number of client computers actively coupled to a server computer system in real-time are discussed herein. Specifically, systems and methods are discussed for a server computer system receiving heartbeat messages from a plurality of client computers and generating an estimate of the number of client computers actively coupled to the server computer system in real-time without locks, such as a database table lock. A heartbeat message from a client computer need not include a client or user identifier. In an embodiment, the memory footprint/overhead is O(l), and may be a single whole number greater than zero, such as a 64-bit unsigned integer. Systems and methods are also discussed herein to calculate and reduce the expected error of the estimated number of active clients.
