1. In the past, we use a BE table named `analysis_jobs` to persist the status of analyze jobs/tasks, however there are many flaws such as, if BE crashed analyze job/task would failed however the status of analyze job/task couldn't get updated. 2. Support `DROP ANALYZE JOB [job_id]` to delete analyze job 3. Support `SHOW ANALYZE TASK STATUS [job_id] ` to get the task status of specific job 4. Restrict the execute condition of auto analyze, only when the last execution of auto analyze job finished a while ago could be executed again 5. Support analyze whole DB
Usage
These scripts are used to make tpc-h test. follow the steps below:
1. build tpc-h dbgen tool.
./bin/build-tpch-dbgen.sh
2. generate tpc-h data. use -h for more infomations.
./bin/gen-tpch-data.sh -s 1
3. create tpc-h tables. modify conf/doris-cluster.conf to specify doris info, then run script below.
./bin/create-tpch-tables.sh
4. load tpc-h data. use -h for help.
./bin/load-tpch-data.sh
5. run tpc-h queries.
./bin/run-tpch-queries.sh
NOTICE: At present, Doris's query optimizer and statistical information functions are not complete, so we rewrite some queries in TPC-H to adapt to Doris' execution framework, but it does not affect the correctness of the results. The rewritten SQL is marked with "Modified" in the corresponding .sql file.
A new query optimizer will be released in subsequent releases.
