By analyzing the technical characteristics of time series database and the storage and processing requirements of massive seismic data,in this paper a seismic waveform data storage and processing system based on time series database is designed and implemented. After developing,testing and application comparing,we found that the new seismic time series database system has the advantages of high availability,large real-time storage throughput,high historical data compression rate,and fast distributed processing speed,which can efficiently solve the storage and processing difficulties caused by rapid growth of seismic waveform data.
