------------------------------
Summary: Optimize transaction data saved to Elasticsearch
Key: SCB-1503
URL: https://issues.apache.org/jira/browse/SCB-1503
Project: Apache ServiceComb
Issue Type: Improvement
Components: Saga
Affects Versions: pack-0.6.0
Reporter: Lei Zhang
The current transaction data push to the memory queue and then stored in the ES
in batches. For better performance, we can set larger value for
`alpha.feature.akka.transaction.repository.elasticsearch.batchSize` (default
value is 100). But it will cause data loss in the queue when JVM crashes. If
you have high-reliability requirements for your data, To avoid data loss, set
batchSize to 0. But there will be performance issues
Maybe we can use Kafka instead of memory queue
