Introduce a SQL syntax for creating inverted index and related metadata changes.
```
-- create table with INVERTED index
CREATE TABLE httplogs (
ts datetime,
clientip varchar(20),
request string,
status smallint,
size int,
INDEX idx_size (size) USING INVERTED,
INDEX idx_status (status) USING INVERTED,
INDEX idx_clientip (clientip) USING INVERTED PROPERTIES("parser"="none")
)
DUPLICATE KEY(ts)
DISTRIBUTED BY RANDOM BUCKETS 10
-- add an INVERTED index to a table
CREATE INDEX idx_request ON httplogs(request) USING INVERTED PROPERTIES("parser"="english");
```
Support running transactional insert operation with new scan framework. eg:
admin set frontend config("enable_new_load_scan_node" = "true");
begin;
insert into tbl1 values(1,2);
insert into tbl1 values(3,4);
insert into tbl1 values(5,6);
commit;
Add some limitation to transactional insert
Do not support non-literal value in insert stmt
Fix some issue about array type:
Forbid cast other non-array type to NESTED array type, it may cause BE crash.
Add getStringValueForArray() method for Expr, to get valid string-formatted array type value.
Add useLocalSessionState=true in regression-test jdbc url
without this config, the jdbc driver will send some init cmd each time it connect to server, such as
select @@session.tx_read_only.
But when we use transactional insert, after begin command, Doris do not support any other type of
stmt except for insert, commit or rollback.
So adding this config to let the jdbc NOT send cmd when connecting.
Support common table expression(CTE) in Nereids：
- Just implemented inline CTE, which means we will copy the logicalPlan of CTE everywhere it is referenced;
- If the name of CTE is the same as an existing table or view, we will choose CTE first;
1.
In the "explain" result of SQL, the table name in `ScanNode` should be full qualified with dbname.
And for olap scan node, the selected index name should not be "null".
2.
Remove `tpch_sf1_p1/tpch_sf1/nereids/` in regression test, it will be fixed later.
Previous logic of reverse function might not be strong enough to handle illegal character. For example, one one byte size character would be mistaken as one utf-8 character which occupies more than one byte space. And unfortunately exceeding the buffer space during future process.
Support delete from partitioned table without partition specified in [DELETE] stmt.
## Usage
If it is a partitioned table, you can specify a partition.
If not specified, Doris will infer partition from the given conditions.
In two cases, Doris cannot infer the partition from conditions:
1) the conditions do not contain partition columns;
2) The operator of the partition column is `not in`.
When a partition table does not specify the partition,
or the partition cannot be inferred from the conditions,
the session variable `delete_without_partition` needs to be `true`
to make delete statement be applied to all partitions.
## Test case
Test case is added in `regression-test/suites/delete_p0/test_delete_from_partition.groovy`,
user can delete from partitioned table without partition specified now.
Issue Number: close#12574
This pr adds `NewJsonReader` which implements GenericReader interface to support read json format file.
TODO:
1. modify `_scann_eof` later.
2. Rename `NewJsonReader` to `JsonReader` when `JsonReader` is deleted.
