Yes, u could delete wal file directly if u understand the risk of it (WAL: Write Ahead Log, u could search the meaning first)

However, from your case, u should better reduce the WAL TTL(Auto Delete) time or reduce the max size of WAL file, u could search it in RocksDBOptions(Normally WAL files are automatically deleted(TTL), adjusting the parameters is the best choice)
