Query a Kusto database with C# and get the result as a List<T>.

This article introduces KustoBuffer, a high-performance non-blocking data buffering component designed to optimize bulk write performance to Kusto databases. The design draws on the implementation approach of ArrayDb, with its core mechanism employing a double-buffering strategy that leverages concurrent queues to decouple data writing from persistence. The system controls the write flow through engine tasks and incorporates a cooling engine mechanism, which dynamically calculates sleep time based on the amount of data in the buffer, thereby balancing write frequency against data fragmentation issues. The article provides detailed code implementations, including thread-safe buffer exchange logic, a logarithmic-function-based sleep time algorithm, and synchronization methods that ensure eventual data consistency. This solution effectively avoids lock contention in high-concurrency scenarios, improves system throughput, and prevents resource waste through fine-grained state management, offering a robust and efficient solution for large-scale data write scenarios.
