How to deal with the query timeout due to large amount of unsequence file in Apache IoTDB?


I found that when the unsequence file in Apache IoTDB is relatively large, some queries proceeded slower and exceeded 60s (the default query_timeout_threshold time) many times, but they are not terminated. Wonder what should I do to speed up these query process?


Solution

  • The unsequence files will affect query performance, but Apache IoTDB can efficiently deal with this problem. You can enable the cross-space merging function to merge the unsequence data files into sequential storage.
