-------------------------------------
Summary: Mailbox reindexing should run faster
Key: JAMES-3175
URL: https://issues.apache.org/jira/browse/JAMES-3175
Project: James Server
Issue Type: Improvement
Components: elasticsearch, mailbox
Affects Versions: 3.5.0
Reporter: Benoit Tellier
On one of Linagora owned plateform, reindexing of 500M emails is conducted at
a speed of 11K email / hour.
This means given our dataset 5 years to conduct the reindexing.
We should speed that up.
The reindexing is performed sequentially, without reactor, and we are paying a
heavy price with all sorts of latencies, interaction is performed with 1 store
at a time (cassandra, elasticSearch, swift are involved), no parallelism is
leveraged.
All steps of reindexing should be done in a reactive fashion.
Acceptance criteria: Performance improvment measured
