How to deal with the `fail to acquire a pending write request` error when executing stream processing plug-in in Apache IoTDB?


About the stream processing plug-in in Apache IoTDB, are there any configuration file or parameters that needs attention? I am now getting an error when executing the plug-in: Ratis request failed: Failed to acquire a pending write request for RaftClientRequest. Anyone know why did I get this error when using stream processing, and how to deal with this error?


Solution

  • Your data writing request in Apache IoTDB is too large and needs to be appropriately reduced. You can consider adjusting config_node_ratis_log_appender_buffer_size_max from 16M to 32M or 64M in the confignode of iotdb-common.properties directory.
