[jira] [Updated] (SAMZA-2688) Elasticity: introduce configs and
sub-partition concept
[ https://issues.apache.org/jira/browse/SAMZA-2688?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Lakshmi Manasa Gaduputi updated SAMZA-2688:
-------------------------------------------
Description:
Introduce config: task.elasticity.factor which defaults to 1. If elasticity factor = 1 then each task consumes the whole input SSP. If elasticity factor = X, then each task is split into X elastic tasks and each elastic task consumes 1/X th of the input SSP. Each of the 1/X th of the input SSP is referred to as the sub-SSP.
Additionally, introduce sub-SSP concept as SystemStreamParitionKeyHash where each SSP has X KeyHashes.

Introduce config: task.elasticity.factor which defaults to 1. If elasticity factor = 1 then each task consumes the whole input SSP. If elasticity factor = X, then each task is split into X virtual tasks and each virtual task consumes 1/X th of the input SSP. Each of the 1/X th of the input SSP is referred to as the sub-SSP.
Additionally, introduce sub-SSP concept as SystemStreamParitionKeyHash where each SSP has X KeyHashes.
