-----------------------------
Summary: Time / Temporal Based Ratis Snapshots
Key: RATIS-1583
URL: https://issues.apache.org/jira/browse/RATIS-1583
Project: Ratis
Issue Type: New Feature
Components: common
Reporter: Nick Z
Currently Ratis only supports triggering snapshots after a certain number of
transactions. However, in some use-cases it is more suitable to use a function
of time rather than a specific number of transactions. This is especially true
if the use-case is bursty or low-volume whereby snapshots may a specific number
may not be met. In these cases it would actually be preferable to have a
combination of time and / or a specific number of transactions. For example -
trigger a snapshot if 60 seconds has passed or 1000 transactions have occurred.
In fact Kafka has a similar concept when flushing a producers message buffer.
This feature request would be especially useful in the context of Apache Ozone.
See the conversation here about how delete operations are delayed when the
number of Ratis transactions hasn't been met :
