| Abstract: | In this paper, we present the study of network middleware of time series database, summarize and analyze the characteristics of common network middleware. According to the high performance requirement of time series database, the key technology of network middleware is studied. The concurrent model of multiple reactor and thread pool is adopted to improve the concurrency of thread, and the multi-frame message format is proposed to realize the dynamic expansion of the message protocol. Finally, the related network middleware is realized in the PCS-9000 time series database. The middleware achieves the expected performance requirements. |
