SLS to DQL Skill
Use this skill to convert Alibaba Cloud SLS queries into GuanceDB DQL and to explain conversion status or diagnostics.
Use Cases
- Convert a single SLS query to DQL.
- Validate whether an SLS query can be safely converted.
- Explain why a query is unsupported.
- Evaluate a batch of real SLS queries.
- Produce Markdown reports for conversion results.
Built-in Resources
- Entry point:
./sls2dql/bin/sls2dql
- Example script:
./sls2dql/scripts/run_sls2dql.sh
- Quick start:
./sls2dql/references/USER_QUICKSTART_zh.md
- User guide:
./sls2dql/references/USER_GUIDE_zh.md
Mandatory Rules
- Always pass
--namespace.
- For search-only queries without SQL
FROM, also pass --source.
- Use
--mode strict by default.
- Use
--mode allow-approximate only when the user accepts approximate semantics.
- Always report conversion status:
exact, approximate, or unsupported.
- For batch work, prefer
report or batch instead of manually stitching results.
Common Commands
./sls2dql/bin/sls2dql version
./sls2dql/bin/sls2dql convert --namespace L --query "SELECT count(*) AS pv FROM access_log"
./sls2dql/bin/sls2dql convert --namespace L --source access_log --query "status:500 AND service:api"
./sls2dql/bin/sls2dql validate --namespace L --query "status:500 | SELECT count(*) AS pv FROM access_log"
./sls2dql/bin/sls2dql explain --namespace L --query "* | SELECT count(*) AS pv FROM access_log GROUP BY host"
Output Requirements
State the command or mode used, whether namespace, source, and index were provided, and the final conversion status. Return final DQL only when the converter produced executable DQL.
