-----------------------------------
Summary: Limit the number of flush/merge threads
Key: ASTERIXDB-2813
URL: https://issues.apache.org/jira/browse/ASTERIXDB-2813
Project: Apache AsterixDB
Issue Type: Improvement
Components: STO - Storage
Reporter: Chen Luo
Assignee: Chen Luo
Currently, AsterixDB uses one thread to execute each flush and merge operation.
This may result in a large number of I/O threads in some cases, e.g., when
writing to many datasets at the same time.
A better solution is to enforce some limit on the number of flush and merge
threads. When there is no thread available, a newly created flush or merge
operation should be delayed.
