Article Introduction：Using a while loop combined with a PHP generator can efficiently process large-scale data sets to avoid memory overflow; 2. The generator returns data one by one through the yield keyword, and only generates values when needed, significantly reducing memory usage; 3. The while loop provides more refined control compared to foreach, supporting early exit, conditional judgment and runtime logic adjustment; 4. This mode is suitable for scenarios such as large file reading, database result streaming processing, such as reading logs line by line or processing user data in batches; 5. Data filtering, conversion and pipeline processing can be achieved through a combination generator to improve code reusability and flexibility; 6. This method has the advantages of low memory consumption, support early termination, and integrated current limiting mechanisms. It is an ideal for handling unlimited or massive data streams.

Article Introduction：Reasons for more efficient processing of data with Stream include memory savings, performance improvements, and support for asynchronous processing. 1. Save memory: avoid loading all data at once through blocking processing; 2. Improve performance: handle read and write operations in parallel; 3. Support asynchronous processing: suitable for non-blocking I/O operations. In the example, the file is read block by block through the Readable stream, and the Writable stream is written to the target file after being converted by the Transform stream. The entire process is low in memory and high in efficiency. In practical applications, attention should be paid to backpressure control, error handling and chain calls of multi-converting streams to ensure stable and efficient stream processing.

Article Introduction：In IoT systems, the key links in data aggregation and processing include data aggregation, edge computing and data cleaning. ① Data aggregation reduces redundant data through timed batch uploads, event triggering or statistical summary; ② Edge computing is initially processed near the device side to reduce delays and improve fault tolerance; ③ Data cleaning removes outliers, completes missing fields and unifies the format, laying the foundation for subsequent analysis. In addition, it is recommended to use message queues to buffer data, adopt a hierarchical processing structure, strengthen monitoring and pre-security mechanisms during deployment to build an efficient and stable data pipeline.

Article Introduction：Geospatial data processing is a technology that ordinary people can master. Its core lies in understanding five steps: first, clarify the data source and format, such as Shapefile, GeoJSON, KML, GPX and PostGIS; second, carry out data cleaning and pre-processing, including deduplication, unified projection, complementary attributes and checking coordinate validity; third, analyze and visualize based on business needs, such as heat map, buffer analysis, distance calculation and cluster analysis; fourth, select appropriate output formats for display or sharing, such as GeoJSON, PDF, PNG, Shapefile or CSV; fifth, attach data descriptions to ensure that others can correctly understand and use them. As long as you master these key points and practice them manually, you can be effective

Article Introduction：WebStreamsAPI is a standard interface for efficient processing of streaming data. It mainly includes three stream types: ReadableStream, WritableStream and TransformStream. It is suitable for large file uploads, real-time audio and video processing and other scenarios. The advantage is that it can process data in chunks, reduce memory usage and improve response speed. When using it, streaming operations are usually combined with FetchAPI or file reading, such as parsing JSON while downloading, or uploading files while reading. Practical applications include file upload optimization, data analysis speedup and real-time audio and video processing. Notes include checking browser compatibility, improving error handling, reasonable control of back pressure and timely shutting down flow to avoid resource leakage

Article Introduction：The key to mastering JavaStreams API is to understand its core concepts and efficient usage methods: 1. Streams are not data structures, do not store elements, and can only be consumed once, and new streams need to be created for each processing; 2. Intermediate operations (such as filters, maps) are lazy, and terminal operations (such as collect, count) trigger actual calculations; 3. Priority is given to using primitive streams such as IntStream to avoid boxing overhead, and use parallelStream with caution, which is only enabled when large data volumes and CPU-intensive tasks; 4. Use Collectors to implement complex result processing such as grouping, partitioning, summary and string connection; 5. Flat-out nested structures using flatMap; 6. Encapsulation

Article Introduction：IAsyncEnumerable is the core feature of asynchronous streaming data introduced in C#8. 1. It realizes non-blocking item-by-item enumeration through awaitforeach, which is suitable for processing large files, database queries, real-time data flows and paging APIs; 2. Compared with Task, it reduces memory usage and supports instant processing; 3. Pay attention to resource release (such as awaitusing), avoids multi-consumer competition, and synchronous blocking calls; 4. It is recommended to use it first in sequence scenarios with high overhead or latency sensitive to improve application scalability and responsiveness.
