The current entity id order > returns entities strictly in the lexicographical order, and as such it > returns the earliest entities first. This may not be the most natural return > order. A more natural return/sort order would be from the most recent > entities. > To solve this, we would like to add what we call the "entity prefix" in the > row key for the entity table. It is a number (long) that can be easily > provided by the client on write. In the row key, it would be added before the > entity id itself. > The entity prefix would be considered mandatory. On all writes (including > updates) the correct entity prefix should be set by the client so that the > correct row key is used. The entity prefix needs to be unique only within the > scope of the application and the entity type. > For queries that return a list of entities, the prefix values will be > returned along with the entity id's. Queries that specify the prefix and the > id should be returned quickly using the row key. If the query omits the > prefix but specifies the id (query by id), the query may be less efficient. > This JIRA should add the entity prefix to the entity API and add its handling > to the schema and the write path. The read path will be addressed in > YARN-5585. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
