wshao08 opened a new pull request #2063: URL: https://github.com/apache/iotdb/pull/2063
A merge lock has already been added locking the whole Last query procedure, however, this procedure may take a long time. This PR refactor the Last query execution process, separating it into multiple stages: 1. Get Last result by accessing cache. 2. Hold merge lock and obtain query resource. 3. Scan TsFiles to get Last value. Now only the stage 2 will be locked. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
