---------------------------------
Summary: Add asynchronous (non-blocking) methods to LEventStore
Key: PIO-182
URL: https://issues.apache.org/jira/browse/PIO-182
Project: PredictionIO
Issue Type: Improvement
Components: Core
Affects Versions: 0.13.0
Reporter: Naoki Takezoe
The current implementation of {{LEventStore}} has only synchronous (blocking)
methods. Since they use {{ExecutionContext.Implicit.global}}, its parallelism
is limited up to the number of processors. This means engine server's
parallelism is also limited if we use these methods in prediction logic.
To solve this problem, {{Future}} version of these methods should be added to
{{LEventStore}} and also current blocking methods should be modified to take
{{ExecutionContext}} (as an implicit parameter).
