Description

I don't need the LOG files which are created here e.g. /var/lib/taos/vnode/vnode4/tq/stream/0x5940669214c1bdd8-0x1d3c08c2/state/LOG as they are getting really large > 1 GB.

I think with the two options max_log_file_size/keep_log_file_num of rocksdb i could limit the size. Is there a way to set both these options?

Contributor guide

Research direction
Check the TDengine documentation for configuring rocksdb options, specifically max log file size and keep log file num. If not documented, explore the source code for how rocksdb is initialized and if these options can be passed through the configuration system.
