* [chore](release build) copy license and notice file to output folder and strip debug info from meta tool
Co-authored-by: yiguolei <yiguolei@gmail.com>
Currently, there are 2 status code in BE, one is common/Status.h,
and the other is olap/olap_define.h called OLAPStatus.
OLAPStatus is just an enum type, it is very simple and could not save many informations,
I will unify these code to common/Status.
Currently, the compiled output of BE mainly consists of two binaries:
palo_be and meta_tool, which are both around 1.6G in size.
However, the debug information is only needed for debugging purposes.
So I separate the debug info from binaries.
After BE is built, the debug info file will be saved in `be/lib/debug_info/` dir.
`palo_be` and `meta_tool`'s size decrease to about 100MB
This is optional, and default is disabled.
To enable it, use:
`STRIP_DEBUG_INFO=ON sh build.sh`
For the first, we need to make a parameter to discribe the data is local or remote.
At then, we need to support some basic function to support the operation for remote storage.
NOTE: This patch would modify all Backend's data.
And this will cause a very long time to restart be.
So if you want to interferer your product environment,
you should upgrade backend one by one.
1. Refactoring be is to clarify the structure the codes.
2. Use unique id to indicate a rowset.
Nameing rowset with tablet_id and version will lead to
many conflicts among compaction, clone, restore.
3. Extract an rowset interface to encapsulate rowsets
with different format.
* Add streaming load feature. You can execute 'help stream load;' to see more information.
Changed:
* Loading phase of a certain table can be parallelized, to reduce the load job execution time when multi load jobs to a single table.
* Using RocksDB to save the header info of tablets in Backends, to reduce the IO operations and increate speeding of restarting.
Fixed:
* A lot of bugs fixed.
