> @HowardQin Hi, if the user is using the lzo before doris 2.0, and then upgrade to this version, there already some data , does it could upgrade successfully? orc::lzoDecompress() can only decompress files compressed by lzop with level 1 to 6, so it's not 100% compatible with liblzo2.a. If old data in segment compressed using lzo with level above 6, this can be a problem, but I do not have enough info. however, currently, doris does not have any code about decompressing lzo data in segment, there's only lzo-decompress logic for loading lzop compressed files. it seems we have already unsupported reading lzo data in segment. -- This is an automated message from the Apache Git Service.
