This Bug is introduced by PR #7936 , which change key type of connectionMap from Long to Integer,
which cause connectionMap could not find connectContext by connectionId
if you want test storage layer vectorized, you need modify some codes to let vectorized storage layer working,
it's boring work.
now, you can just change one code (redefine the macro STORAGE_LAYER_VECTORIZED_SWITCH as 1 or 0),
this gets more convenient.
Support thread pool per disk for scanners to prevent pool performance from some high ioutil disks happening
key point:
1. each disk has a thread pool for scanners
2. whenever a thread pool of one disk runs out of local work, tasks can be retrieved from other threads(disks). This is done round-robin.
performance testing:
vec version: 25% faster than single thread pool in a high io util disk test case
normal version: 8% faster than single thread pool in a high io util disk test case
Enable to check the Java version when Doris starts, to prevent the user experience caused by the inconsistency
between the compiled version and the running version.
If the Java version is compiled and the Java version is run, it will not start, and a prompt message will be given.
1. Fix the problem of BE crash caused by destruct sequence. (close#8058)
2. Add a new BE config `compaction_task_num_per_fast_disk`
This config specify the max concurrent compaction task num on fast disk(typically .SSD).
So that for high speed disk, we can execute more compaction task at same time,
to compact the data as soon as possible
3. Avoid frequent selection of unqualified tablet to perform compaction.
4. Modify some log level to reduce the log size of BE.
5. Modify some clone logic to handle error correctly.
1. Support some function alias of mod/fmod, adddate/add_data
2. Support some function of multi args: week, yearweek
3. Fix bug of multi args function call the DATETIME type not effective in DATE type
Sometimes BE is build on a machine with SIMD instruction such as AVX2.
But the BE binary will be copied to a machine without AVX2. It will crashed without any error message.
This PR will check the required SIMD instructions and print error messages during startup.
Hive Bitmap UDF provides UDFs for generating bitmap and bitmap operations in hive tables.
The bitmap in Hive is exactly the same as the Doris bitmap.
The bitmap in Hive can be imported into Doris through spark bitmap load.
The two phase batch commit means：
During Stream load, after data is written, the message will be returned to the client,
the data is invisible at this point and the transaction status is PRECOMMITTED.
The data will be visible only after COMMIT is triggered by client.
1. User can invoke the following interface to trigger commit operations for transaction：
curl -X PUT --location-trusted -u user:passwd -H "txn_id:txnId" -H "txn_operation:commit" \
http://fe_host:http_port/api/{db}/_stream_load_2pc
or
curl -X PUT --location-trusted -u user:passwd -H "txn_id:txnId" -H "txn_operation:commit" \
http://be_host:webserver_port/api/{db}/_stream_load_2pc
2.User can invoke the following interface to trigger abort operations for transaction：
curl -X PUT --location-trusted -u user:passwd -H "txn_id:txnId" -H "txn_operation:abort" \
http://fe_host:http_port/api/{db}/_stream_load_2pc
or
curl -X PUT --location-trusted -u user:passwd -H "txn_id:txnId" -H "txn_operation:abort" \
http://be_host:webserver_port/api/{db}/_stream_load_2pc
Framework code for statistics collection,
containing only the main data structures, no implementation details.
This pr will not affect any existing code
and users will not be able to create statistics job.
1. set both `tuple_offsets` and `new_tuple_offsets` in PRowBatch for compatibility
2. set FE config `repair_slow_replica` default to false
Avoid impacting the load process after upgrading.
Eg, if there are only 2 replicas, one is with high version count. After upgrade,
that replica will be set to bad, so that the load process will be stopped
because only 1 replica is alive.
3. Fix a bug that NodeChannel may be blocked at `close_wait()`
Forget to set `add_batch_finish` flag after the last rpc finished.
4. Fix a NPE of RoutineLoadScheduler
