* Support TRUNCATE TABLE stmt
User can use TRUNCATE TABLE stmt to empties a table
or partitions completely.
Unlike DELETE, it will drop the tablets directly, and
without any performance impact.
* Fix bugs that new partition should use new ID
* Use equals() to compare Integer
* Fix compile bug
* Fix bug on single range parititon
* Check table's state again after creating partition
* Avoid 'No more data to read' error when handling stream load rpc
1. Catch throwable of all stream load rpc.
2. Avoid setting null string as error msg of rpc result status.
* Change setError_msgs to addToError_msgs
1. Only collect all error replicas if publish task is timeout.
2. Add 2 metrics to monitor the success of failure of txn.
3. Change publish timeout to Config.load_straggler_wait_second
1. Use the data size save in tablet's header to calculate the disk used capacity.
2. Decrease the default interval of disk and tablet report, from 10 min to 1 min.
Step1: updateBeIdTaskMaps, remove unavailable BE and add new alive BE
Step2: process timeout tasks, if a task has already been allocated to BE but not finished before DEFAULT_TASK_TIMEOUT, it will be discarded.
At the same time, the partitions belong to old tasks will be allocated to a new task. The new task with a signature will be added in the queue of needSchedulerRoutineLoadTask.
Step3: process all needSchedulerRoutineLoadTasks, allocate task to BE. The task will be executed by BE.
* Fix bug of #307
There is a bug to use symbolic link directory as storage root path.
It is a problem that whether the path is canonical
In DownloadAction, checking fails by comparing canonical path with non-canonical path.
So fix the bug by convert all path to canonical path before comparison
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
