Class definition of ByteBuffer duplicates between olap/byte_buffer.h and util/byte_buffer.h.
All of the two classes has a function names as remaining().
Some place which want to call remaining() of util/byte_buffer.h is linked to the other remaining() function of olap/byte_buffer.h
* Modify partition's version name to what it means.
1. committedVersion(Hash) -> visibleVersion(Hash)
2. currentVersion(Hash) -> committedVersion(Hash)
3. add some comment to make the code more readable
* Check if editlog is null in CatalogIdGenerator
To avoid unit test failure
* Support for custom build toolchains
ISSUE #297
Locate the header file path of DORIS_GCC_HOME, add them to the CPLUS_INCLUDE_PATH environment variable.
So clang can find it.
* Compatible with custom toolchain for clang
ISSUE #297
1. Find default header file paths of DORIS_GCC_HOME and set as enviroment variable CLANG_COMPATIBLE_FLAGS.
2. Explicitly add these paths to CLANG_INCLUDE_FLAGS.
* Change PaloMetrics' name and Catalog's Id generator
1. Remove 'Palo' prefix of class Metric.
2. Add a new CatalogIdGenerator to replace the old AtomicLong, to avoid too many edit logs.
3. Add a new histogram to monitor write letency of edit log write.
* modify next id logic
* fix a bug that Metric is not init before using HISTO_EDIT_LOG_WRITE_LATENCY
* fix a problem
Add path info of replica in catalog
Also fix a bug that when calling check_none_row_oriented_table,
store is null, it cannot be used to create table.
Instead, OLAPHeader can be used to get storage type information.
* Reduce UT binary size
Almost every module depend on ExecEnv, and ExecEnv contains all
singleton, which make UT binary contains all object files.
This patch seperate ExecEnv's initial and destory to anthor file to
avoid other file's dependence. And status.cc include debug_util.h which
depend tuple.h tuple_row.h, and I move get_stack_trace() to
stack_util.cpp to reduce status.cc's dependence.
I add USE_RTTI=1 to build rocksdb to avoid linking librocksdb.a
Issue: #292
* Update
Currently, the cardinality, avgRowSize, numNodes stat info in OlapScanNode is none, So the broadcastCost and partitionCost are both wrong and Doris couldn't auto choose a best join strategy.
So we should make the statistical information in OlapScanNode more precise.
Allow User specify the null ordering
NULLS FIRST: specifies that NULL values should be returned before
non-NULL values.
NULLS LAST: specifies that NULL values should be returned after
non-NULL values.
