Kunal Khatua updated DRILL-6076: -------------------------------- Labels: (was: ready-to-commit) > Reduce the default memory from a total of 13GB to 5GB > ----------------------------------------------------- > > Key: DRILL-6076 > URL: https://issues.apache.org/jira/browse/DRILL-6076 > Project: Apache Drill > Issue Type: Task > Reporter: Kunal Khatua > Assignee: Kunal Khatua > Priority: Critical > Fix For: 1.13.0 > > Original Estimate: 24h > Remaining Estimate: 24h > > Currently, the default memory requirements for Drill are about 13GB, with the > following allocations: > * 4GB Heap > * 8GB Direct Memory > * 1GB CodeCache > * 512MB MaxPermSize > Also, with Drill 1.12.0, the recommendation is to move to JDK8, which makes > the MaxPermSize as irrelevant. > With that, the default requirements total to 13GB, which is rather high. This > is especially a problem for scenarios where people are trying out Drill and > might be using this in a development environment where 13GB is too high. > When using the public [test > framework|https://github.com/mapr/drill-test-framework/] for Apache Drill, it > was observed that the framework's functional and unit tests passed > successfully with memory as little as 5GB; based on the following allocation: > * 1GB Heap > * 3GB Direct Memory > * 512MB CodeCache > * 512MB MaxPermSize > Based on this finding, the proposal is to reduce the defaults from the > current settings to the values just mentioned above. The drill-env.sh file > already has details in the comments, along with the recommended values that > reflect the original 13GB defaults. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
