ASF GitHub Bot updated HDDS-3479:
---------------------------------
Labels: newbie pull-request-available (was: newbie)
> Use SCMMetadataStore instead of low level DBStore
> -------------------------------------------------
>
> Key: HDDS-3479
> URL: https://issues.apache.org/jira/browse/HDDS-3479
> Project: Hadoop Distributed Data Store
> Issue Type: Improvement
> Reporter: Marton Elek
> Priority: Major
> Labels: newbie, pull-request-available
>
> Suggested by Nanda in https://github.com/apache/hadoop-ozone/pull/700
> Context: we have a low-level DBStoreBuilder with separated DB definition
> (SCMDBDefinition). But as we have a higher level wrapper class
> (scmMetadataStore) It seems to be more reasonable to use ScmMetadataStore
> everywhere inside SCM
> (Currently It's called SCMMetadataStoreRDBImpl but it's proposed to remove
> R(DB) from the name as it's no more RocksDB specific)
> bq. If we are going with renaming and using it, it's better to use
> SCMMetadataStoreRDBImpl in all the places rather than
> DBStoreBuilder.createDBStore(conf, new SCMDBDefinition()
> bq.
> Instead of this:
> {code}
> DBStore dbStore = DBStoreBuilder.createDBStore(conf, new SCMDBDefinition());
> Table<PipelineID, Pipeline> pipelineTable =
> SCMDBDefinition.PIPELINES.getTable(dbStore);
> dbStore.close();
> {code}
> we can use this:
> {code}
> SCMMetadataStore scmMetadataStore = new SCMMetadataStoreRDBImpl(conf);
> Table<PipelineID, Pipeline> pipelineTable =
> scmMetadataStore.getPipelineTable();
> scmMetadataStore.close();
> {code}
