Summary: s3guard: implement time-based (TTL) expiry for
LocalMetadataStore
Key: HADOOP-13649
URL: https://issues.apache.org/jira/browse/HADOOP-13649
Project: Hadoop Common
Issue Type: Sub-task
Components: fs/s3
Reporter: Aaron Fabbri
Assignee: Aaron Fabbri
LocalMetadataStore is primarily a reference implementation for testing. It may
be useful in narrow circumstances where the workload can tolerate short-term
lack of inter-node consistency: Being in-memory, one JVM/node's
LocalMetadataStore will not see another node's changes to the underlying
filesystem.
To put a bound on the time during which this inconsistency may occur, we should
implement time-based (a.k.a. Time To Live / TTL) expiration for
LocalMetadataStore
