-------------------------------------
Summary: Avoid transaction state cache refresh on co-procesor
startup
Key: TEPHRA-270
URL: https://issues.apache.org/jira/browse/TEPHRA-270
Project: Tephra
Issue Type: Improvement
Components: core
Reporter: Poorna Chandra
Assignee: Poorna Chandra
Fix For: 0.14.0-incubating
Transaction state cache, on startup, refreshes the transaction snapshot from
HDFS. The transaction state cache startup is called during HBase co-processor
startup. The refresh of the transaction snapshot can block, thus blocking the
co-processor startup.
The subsequent transaction snapshot refreshes happen in the background Also -
there is no guarantee that a snapshot will be present during the refresh on
startup. Hence it is okay not to refresh the snapshot during snapshot, but do
it in background.
