When I upgrade IoTDB to version 0.12.3, I could not query for more than 1000 timeseries anymore. Even I modified the configuration max_deduplicated_path_num, I could still get the error: Too many paths in one query! Currently allowed max deduplicated path number is 1000. Please use slimit or adjust max_deduplicated_path_num in iotdb-engine.properties.

it is a bug in v0.12.3, and it would be fixed in v0.12.4, which will be released recently. Currently, you could uncomment this configuration: chunk_timeseriesmeta_free_memory_proportion=1: 100:200:300:400. And then, the modification of max_deduplicated_path_num would take effect.
