Summary: S3Guard: add support for other MetadataStores
Key: HADOOP-16875
URL: https://issues.apache.org/jira/browse/HADOOP-16875
Project: Hadoop Common
Issue Type: Wish
Affects Versions: 3.2.1
Reporter: Rafael Acevedo
Hi all,
Are there any plans to add other MetadataStore implementations for S3Guard?
DynamoDB costs are too high when the read capacity/write capacity are high.
Maybe a Postgres/MySQL implementation is simple enough to implement and offer
strong consistency.
Another idea is to implement a Cassandra/Scylla MetadataStore(for better write
scalability), but we should pay attention to consistency.
Any thoughts?
