For[Spark Load]
1 support decimal andl largeint
2 add validate logic for char/varchar/decimal
3 check data load from hive with strict mode
4 support decimal/date/datetime aggregator
When Doris create a database, the database of data quota and replica quota is initialized by configuration(Config.default_db_data_quota_bytes and Config.default_db_replica_quota_bytes).
In other words, I convert FeConstants.default_db_data_quota_bytes to Config.default_db_data_quota_bytes
Config.default_db_data_quota_bytes can be change in configuration file.
When fe replay rollup job(v1) with deleted table, it will throw null pointer exception and exit.
This commit ignore this error and print a warning log to avoid fe exit.
Fixed#4571

Fix stale path delete checking logic.
When current main path is version missing, then delete checking logic is always core dumped. So we fix the checking logic to tolerate current main version missing.
After tablet level metrics is supported, the http metrics API may response
a very large body when a BE holds a large number of tablets, and cause heavy
network traffic.
This patch introduce http content compression to reduce network traffic.
Many tables are so large that need seperate partitions with "HOUR" time unit.
But now dynamic partition doesn't support "HOUR" time unit and it was marked as "TODO".
So I support the feature and it works.
Add tracing broker log. When fe get filestatus for distributing load task to broker,
the broker maybe get empty files and not give correct error code.
Add this log to easy track which broker process filestatus operation and we can get the error log.
BE can not graceful exit because some threads are running in endless
loop. This patch do the following optimization:
- Use the well encapsulated Thread and ThreadPool instead of std::thread
and std::vector<std::thread>
- Use CountDownLatch in thread's loop condition to avoid endless loop
- Introduce a new class Daemon for daemon works, like tcmalloc_gc,
memory_maintenance and calculate_metrics
- Decouple statistics type TaskWorkerPool and StorageEngine notification
by submit tasks to TaskWorkerPool's queue
- Reorder objects' stop and deconstruct in main(), i.e. stop network
services at first, then internal services
- Use libevent in pthreads mode, by calling evthread_use_pthreads(),
then EvHttpServer can exit gracefully in multi-threads
- Call brpc::Server's Stop() and ClearServices() explicitly
We store all table ids involved in the Load Job in TransactionState.
However, for Hadoop Load job, table ids are set incorrectly.
This caused the WAITING_TXN phase to not correctly wait for the completion
of the previous load transaction when doing the alter table,
which caused some data version loss problems.
Fix segment group add zone map bug when schema change.
(1) WrapperField null point check
(2) in DUP_KEYS, let _zone_maps index consistent with _schema column index
we can create odbc_table use SQL like
```
CREATE EXTERNAL TABLE `baseall_oracle` (
`k1` decimal(9, 3) NOT NULL COMMENT "",
`k2` char(10) NOT NULL COMMENT "",
`k3` datetime NOT NULL COMMENT "",
`k5` varchar(20) NOT NULL COMMENT "",
`k6` double NOT NULL COMMENT ""
) ENGINE=ODBC
PROPERTIES (
"host" = "192.168.0.1",
"port" = "8086",
"user" = "happenlee",
"password" = "doris",
"database" = "doris",
"table" = "baseall",
"driver" = "Oracle 19 ODBC driver",
"type" = "oracle"
);
```
Now we only support Oracle and MySQL Database and this feature default turned off by conf enable_odbc_table.
Main CL:
1. Copy the code from BE to implement the `str_to_date()` function in FE.
2. `str_to_date("2020-08-08", "%Y-%m-%d %H:%i:%s")` will return `2020-08-08 00:00:00` instead of `2020-08-08`.
It is possible to report "Illegal column/field reference'table2.DORIS_DELETE_SIGN' of semi-/anti-join"
when executing a semi/anti join statement on a table with hidden columns.
This is because the filter conditions of semi/anti join cannot added in the where statement.
Now we add delete flag related where predicate in OlapScanNode level.
The parameter 'part' of parse_url function does not support lower case, and parse protocol not right.
And This function does not support parse 'port'.
This PR tries to make parse_url function case insensitive and support parse 'port'.
The issue: #4451
(1) fix recover persistent stale rowsets bug from multi-single version rowset in stale rowsets
(2) delete_expired_inc_rowsets check consistent version convert to [0, max_version]
1. Analyze what mode of cache can be used by query
2. Query cache before executing query in StmtExecutor
3. Two cache mode, sqlcache and partitioncache, are implemented
The param of rand() function should be literal, but current compiler ignore to
validate the literal param of rand function, it is validated in execution step.
This PR make it validated in compile step, and make it more earlier to find the usage error of rand() function.
Sometimes we want to detect the hotspot of a cluster, for example, hot scanned tablet, hot wrote tablet,
but we have no insight about tablets in the cluster.
This patch introduce tablet level metrics to help to achieve this object, now support 4 metrics on tablets: `query_scan_bytes `, `query_scan_rows `, `flush_bytes `, `flush_count `.
However, one BE may holds hundreds of thousands of tablets, so I add a parameter for the metrics HTTP request,
and not return tablet level metrics by default.
In DistributedPlanner, do not add the unnecessary Exchanges.
For case 1, we only need to judge that the table's distribute hash keys is a subset of the aggregate keys.
For case 2, we should judge two conditions:
- partition keys are also hash keys.
- the table's distribute hash keys is a subset of the aggregate keys.
1. When WITH_MYSQL is off, load error hub does not suport MySQL load error hub,
we should check its return value.
2. misjudge the return value of `change_row_block` in schema_change.cpp
