doris/be/src/exec/schema_scanner/schema_tables_scanner.cpp:330:24: run
Usage: ./build-thirdparty.sh [options...] [packages...]
Optional options:
-j <num> build thirdparty parallel
--clean clean the extracted data
--continue <package> continue to build the remaining packages (starts from the specified package)
Examples:
1. Specify packages to build.
Build gflags, gtest and glog by executing ./build-thirdparty.sh gflags gtest glog.
2. Continue to build the remaining packages.
Build the remaining packages (starts from sse2neon) by executing ./build-thirdparty.sh --continue sse2neon.
We can support this by add a new properties for tvf, like :
`select * from hdfs("uri" = "xxx", ..., "compress_type" = "lz4", ...)`
User can:
Specify compression explicitly by setting `"compression" = "xxx"`.
Doris can infer the compression type by the suffix of file name(e.g. `file1.gz`)
Currently, we only support reading compress file in `csv` format, and on BE side, we already support.
All need to do is to analyze the `"compress_type"` on FE side and pass it to BE.
With the default config of 90%, be may meet OOM when the load pressure is big.
when set to 80%, be works well with the same load pressure in my cluster.
The core is due to a DCHECK:
F0513 22:48:56.059758 3996895 tablet.cpp:2690] Check failed: num_to_read == num_read
Finally, we found that the DCHECK failure is due to page cache:
1. At first we have 20 segments, which id is 0-19.
2. For MoW table, memtable flush process will calculate the delete bitmap. In this procedure, the index pages and data pages of PrimaryKeyIndex is loaded to cache
3. Segment compaction compact all these 10 segments to 2 segment, and rename it to id 0,1
4. Finally, before the load commit, we'll calculate delete bitmap between segments in current rowset. This procedure need to iterator primary key index of each segments, but when we access data of new compacted segments, we read data of old segments in page cache
To fix this issue, the best policy is:
1. Add a crc32 or last modified time to CacheKey.
2. Or invalid related cache keys after segment compaction.
For policy 1, we don't have crc32 in segment footer, and getting the last-modified-time needs to perform 1 additional disk IO.
For policy 2, we need to add additional page cache invalidation methods, which may cause the page cache not stable
So I think we can simply add a file size to identify that the file is changed.
In LSM-Tree, all modification will generate new files, such file-name reuse is not normal case(as far as I know, only segment compaction), file size is enough to identify the file change.
fix some wrong downcast founded by ubsan.
```cpp
doris/be/src/olap/bloom_filter_predicate.h:43:32: runtime error: downcast of address 0x7f8ec2b691a0 which does not point to an object of type 'doris::BloomFilterColumnPredicate<doris::TYPE_DATE>::SpecificFilter' (aka 'BloomFilterFunc<(doris::PrimitiveType)11U>')

^~~~~~~~~~~~~~~~~~~~~~~
vptr for 'doris::BloomFilterFunc<(doris::PrimitiveType)12>'
```
1. TYPE_DATE/TYPE_DATETIME have same data format, so I change the cast about bloom filter to reinterpret cast.
```cpp
doris/be/src/vec/exec/format/orc/vorc_reader.h:281:17: runtime error: downcast of address 0x7f562f4c3180 which does not point to an object of type 'ColumnVector<int>'

^~~~~~~~~~~~~~~~~~~~~~~
vptr for 'doris::vectorized::ColumnDecimal<doris::vectorized::Decimal<int> >'
```
2. doris use ColumnDecimal to store decimal elements.
1. fix function define of `Retention` inconsist, this function return tinyint on `FE` and return uint8 on `BE`
2. make assert_cast support cast to derived
3. change some static cast to assert cast
4. support sum(bool)/avg(bool)
