#18015 enables stream load profile log, however be will encounter rpc fail when loading tpch data(see #18291). This is because when `is_report_success` is true, be will reportExecStatus to fe, but fe cannot find QueryInfo in `coordinatorMap`, thus it will return error to be.
1. Introduce hadoop libhdfs
2. For Linux-X86 platform, use the hadoop libhdfs
3. For other platform, use libhdfs3, because currently we don't have hadoop libhdfs binary for other platform

Remove page cache regular clear
Now the page cache is turned off by default. If the user manually opens the page cache, it can be considered that the user can accept the memory usage of the page cache, and then can consider adding a manual clear command to the cache.
fix memory gc cancel top memory query
jemalloc prof is not enabled by default
Follow #17586.
This PR mainly changes:
Remove env/
Remove FileUtils/FilesystemUtils
Some methods are moved to LocalFileSystem
Remove olap/file_cache
Add s3 client cache for s3 file system
In my test, the time of open s3 file can be reduced significantly
Fix cold/hot separation bug for s3 fs.
This is the last PR of #17764.
After this, all IO operation should be in io/fs.
Except for tests in #17586, I also tested some case related to fs io:
clone
concurrency query on local/s3/hdfs
load error log create and clean
disk metrics
See #17764 for details
I have tested:
- Unit test for local/s3/hdfs/broker file system: be/test/io/fs/file_system_test.cpp
- Outfile to local/s3/hdfs/broker.
- Load from local/s3/hdfs/broker.
- Query file on local/s3/hdfs/broker file system, with table value function and catalog.
- Backup/Restore with local/s3/hdfs/broker file system
Not test:
- cold & host data separation case.
Read IO would be a problem when reading inverted index from disk.
Using read buffer to reduce IO.
Set use buffer flag to be true when reading internal bytes in compound reader for inverted index.
Fix MacOS mem_limit parse result is 0.
Fix GC after env Init, otherwise, when the memory is insufficient, BE will start failure.

1. change PipelineTaskState to enum class
2. remove some row-based code on FoldConstantExecutor::_get_result
3. reduce memcpy on minmax runtime filter function(Now we can guarantee that the input data is aligned)
4. add Wunused-template check, and remove some unused function, change some static function to inline function.
Modify the default value of mem_limit to auto. auto means process mem limit is equal to max(physical mem * 0.9, 6.4G).
6.4G is the maximum memory reserved for the system.
fix heap-use-after-free
The OrcReader has a internal FileInputStream, If the file is empty, the memory of FileInputStream will leak.
Besides, there is a Statistics instance in FileInputStream. FileInputStream maybe delete if the orc reader
is inited failed, but Statistics maybe used when orc reader is closed, causing heap-use-after-free error.
Potential memory leak
When init file scanner in file scan node, the file scanner prepare failed, the memory of file scanner will leak.
We set LIBHDFS3_CONF env in start_be.sh, so libhdfs3 will try to read this hdfs-site.xml,
if file does not exist, it will throw error. But Doris does not handle this error, cause BE crash.
This CL mainly changes:
Modify start_be.sh to only set LIBHDFS3_CONF if hdfs-site.xml exist.
Refactor the HDFSCommonBuilder so that it can return error correctly.
Add BE IP info in status, so that we can get ip from error msg like:
ERROR 1105 (HY000): errCode = 2, detailMessage = [INTERNAL_ERROR]failed to init reader for file 000.snappy.orc, err:
[INTERNAL_ERROR][172.21.0.101]failed to init HDFSCommonBuilder, please check check be/conf/hdfs-site.xml
The logic of prefer compute node is wrong, which causing the external table query can only assign up to 3 backends.
This CL refactor this logic and also change some FE config:
prefer_compute_node_for_external_table
If set to true, query on external table will prefer to assign to compute node.
And the max number of compute node is controlled by min_backend_num_for_external_table.
If set to false, query on external table will assign to any node.
min_backend_num_for_external_table
Only take effect when prefer_compute_node_for_external_table is true.
If the compute node number is less than this value, query on external table will try to get some mix node
to assign, to let the total number of node reach this value.
If the compute node number is larger than this value, query on external table will assign to compute node only.
Add a special counter for memtracker, faster, but relaxed ordering and not accurate in real time
Track thread create and destroy memory, which was previously removed due to performance loss and added back
BloomFilter in MoW table may consume lots of memory, and it's life cycle is same as segment. This patch try to improve the efficiency of recycling segment cache, to release the memory in time.
Sense io error.
Retry query when io error.
Greylist: When finds one disk is completely broken, or the diff of tablet number in BE and FE meta is too large,reduce the query priority of the BE.
Fix Redhat 4.x OS /proc/meminfo has no MemAvailable, disable MemAvailable to control memory.
vm_rss_str and mem_available_str recorded when gc is triggered, to avoid memory changes during gc and cause inaccurate logs.
join probe catch bad_alloc, this may alloc 64G memory at a time, avoid OOM.
Modify document doris_be_all_segments_num and doris_be_all_rowsets_num names.
Fulltext index is the inverted index of the specified tokenizer, before this pr, fulltext index only can evaluate match predicate, this pr to support evaluate equal predicate and list predicate.
mainly include:
- brpc service adds two types of thread pools. The number of "light" and "heavy" thread pools is different
Classify the interfaces of be. Those related to data transmission are classified as heavy interfaces and others as light interfaces
- Add some monitoring to the thread pool, including the queue size and the number of active threads. Use these
- indicators to guide the configuration of the number of threads
There are 2 kinds for scanner thread pool, local and remote.
Local is for local file read, specially for olap scanner.
Remote is for other external data source, such as file scanner, jdbc scanner.
This PR mainly changes:
For olap scanner, use cold or hot rowset to decide whether to use local or remote pool.
For other scanner, user remote pool by default.
Add a new BE config doris_max_remote_scanner_thread_pool_thread_num, default is 512,
indicate the max thread number of the remote scanner thread pool
This will alleviate the problem of interaction between olap queries with load job and external queries.
The element in InvertedIndexSearcherCache is inverted index searcher, which is a file descriptor of inverted index file, so InvertedIndexSearcherCache is actually cache file descriptor of inverted index file.
If open file descriptor limit of the Linux system is set too small and config inverted_index_searcher_cache_limit is too big, during high pressure load maybe cause "Too many open files".
So, when insert inverted index searcher into InvertedIndexSearcherCache, need also check whether reach file_descriptor_number limit for inverted index file.
Support IPV6 in Apache Doris, the main changes are:
1. enable binding to IPV6 address if network priority in config file contains an IPV6 CIDR string
2. BRPC and HTTP support binding to IPV6 address
3. BRPC and HTTP support visiting IPV6 Services
Use FE cluster token to auth stream load.
This auth is only open for be, and fe auth still only support http basic auth.
I will use this auth for mysql load to build a no-auth stream load from fe to be.
And this will avoid double auth in mysql load.
More information to see the design doc.
Add cache for inverted index query match bitmap to accelerate common query keyword, especially for keyword matching many rows.
Tests result:
- large result: matching 99% out of 247 million rows shows 8x speed up.
- small result: matching 0.1% out of 247 million rows shows 2x speed up.
Issue Number: close#16351
Dynamic schema table is a special type of table, it's schema change with loading procedure.Now we implemented this feature mainly for semi-structure data such as JSON, since JSON is schema self-described we could extract schema info from the original documents and inference the final type infomation.This speical table could reduce manual schema change operation and easily import semi-structure data and extends it's schema automatically.
