1. Add a new dynamic partition property `create_history_partition`.
If set to true, Doris will create all partitions from `start` to `end`.
2. Add a new FE config `max_dynamic_partition_num`
To limit the number of partitions created when creating one table.
MemTracker can provide memory consumption for us to find out which
module consume more memory, but it's just a current value, this patch
add metrics for some large memory consumers, then we can find out
which module consume more memory in timeline, it would be useful to
troubleshoot OOM problems and optimize configs.
* [Enhance] Make MemTracker more accurate (#5515)
This PR main about:
1. Improve the readability of MemTrackers' name
2. Add the MemTracker of:
* Load
* Compaction
* SchemaChange
* StoragePageCache
* TabletManager
3. Change SchemaChange to a Singleon
* revise some code for Code Review
* change the name of mem_tracker
* keep reader_context have the same lifetime of rowset_reader in schema change.
* change vlog notice to log(warning) in schema change
* update gcc to gcc 10 and support c++17
update brpc to 0.9.7
update boost to 1.73
remove third-party boost 1.54 for mysql
* update cmake version
* ignore jdk version
* remove unused patch
* avoid use SYS_getrandom call
* [Enhance] Sort directories by available space when do trash sweep
In the case when one disk is about to be full, we want to sweep trash
data on this disk as quickly as possible. The currently trash sweep
function is to remove trashed files order by path's name, however, disk
data directories may have some large different available space because
of the load balance algorithm, this patch improve it to remove files by
directories' available space.
* add log
Some invalid config value may cause BE work in an unexpected behavior,
this patch aim to support config validating when BE bootstrap and update BE's config by API
to reject invalid value.
This is a work to accomplish PR #4423

In the previous broker load, multiple OlapTableSinks would send data to the same LoadChannel,
and because of the lock granularity problem, LoadChannel could only process these requests serially,
which made it impossible to make full use of cluster resources.
This CL modifies the related locks so that LoadChannel can process these requests in parallel.
In the test, with a size of 20G, the load speed of 334 million rows of data in 3 nodes has been
increased from 9min to 5min, and after enabling 2 concurrency, it can be increased to 3min.
Also modify the profile of load job.
1. Add BlockColumnPredicate support OR and AND column predicate in RowBlockV2
2. Support evaluate vectorization delete predicate in storage engine not in Reader in SegmentV2
Support conditional filtering of original data in broker load and routine load
eg:
```
LOAD LABEL `label1`
(
DATA INFILE ('bos://cmy-repo/1.csv')
INTO TABLE tbl2
COLUMNS TERMINATED BY '\t'
(event_day, product_id, ocpc_stage, user_id)
SET (
ocpc_stage = ocpc_stage + 100
)
PRECEDING FILTER user_id = 1381035
WHERE ocpc_stage > 30
)
...
```
In version 0.13, we support a more efficient compaction logic.
This logic will maintain multiple version paths of the tablet.
This can avoid -230 errors and can also support incremental clone.
But the previous incremental clone uses the incremental rowset meta recorded in `incr_rs_meta`.
At present, the incremental rowset meta recorded in `incr_rs_meta` and the records
in `stale_rs_meta` are duplicated, and the current clone logic does not adapt to the
new multi-version path, resulting in many cases not triggering incremental clone.
This CL mainly modified:
1. Removed `incr_rs_meta` metadata
2. Modified the clone logic. When the clone is incremented, it will try to read the rowset in `stale_rs_meta`.
3. Delete a lot of code that was previously used for version compatibility.
At present, the application of vlog in the code is quite confusing.
It is inherited from impala VLOG_XX format, and there is also VLOG(number) format.
VLOG(number) format does not have a unified specification, so this pr standardizes the use of VLOG
ThreadSanitizer, aka TSAN, is a useful tool to detect multi-thread
problems, such as data race, mutex problems, etc.
We should detect TSAN problems for Doris BE, both unit tests and
server should pass through TSAN mode, to make Doris more robustness.
This is the very beginning patch to fix TSAN problems, and some
difficult problems are suppressed in file 'tsan_suppressions', you
can suppress these problems by setting:
export TSAN_OPTIONS="suppressions=tsan_suppressions"
before running:
`BUILD_TYPE=tsan ./run-be-ut.sh --run`
#4995
**Implementation of Separated Page Cache**
- Add config "index_page_cache_ratio" to set the ratio of capacity of index page cache
- Change the member of StoragePageCache to maintain two type of cache
- Change the interface of StoragePageCache for selecting type of cache
- Change the usage of page cache in read_and_decompress_page in page_io.cpp
- add page type as argument
- check if current page type is available in StoragePageCache (cover the situation of ratio == 0 or 1)
- Add type as argument in superior call of read_and_decompress_page
- Change Unit Test
#5146
Add histogram metrics into util/metrics.h. The data structure of histogram is implemented in util/histogram.h,
which could also be used in other situations that in need of histogram. Unit tests added as well.
There are some long loops and sleeps in unit tests, it will cost a
very long time to run all unit tests, especially run in TSAN mode.
This patch speed up unit tests by shortening long loops and sleeps,
on my environment all unit tests finished in 1 minite. It's useful
to do basic functional unit tests.
You can switch to run in this mode by adding a new environment variable
'DORIS_ALLOW_SLOW_TESTS'. For example, you can set:
export DORIS_ALLOW_SLOW_TESTS=1
and also you can disable it by setting:
export DORIS_ALLOW_SLOW_TESTS=0
When partition cache is not cached continuely, range query may fail.
For example, partition key 20201011 and 20201013 is cached,
but rang query is between 20201011 and 20201013, the query will not hit the cache.

This is a udaf for approximate topn using Space-Saving algorithm. At present, we can only calculate
the frequent items and their frequencies in a certain column, based on which we can implement similar
topN functions supported by Kylin in the future.
I have also added a test to calculate the accuracy of this algorithm. The following is a rough running result.
The total amount of data is 1 million lines and follows the Zipfian distribution, where Element Cardinality
represents the data cardinality, 20X, 50X.. The value representing space_expand_rate is 20,50, which is
used to set the counter number in the space-saving algorithm
```
zf exponent = 0.5
Element cardinality 20X 50X 100X
1000 100% 100% 100%
10000 100% 100% 100%
100000 100% 100% 100%
500000 94% 98% 99%
zf exponent = 0.6，1
Element cardinality 20X 50X 100X
1000 100% 100% 100%
10000 100% 100% 100%
100000 100% 100% 100%
500000 100% 100% 100%
```
Mistakenly use the string '_engine_data_path' as the path, actually the storage engine is not open,
so option/path is needless. Cleanup it to avoid any doubt about the file path management.
