-----------------------------------
Summary: API command to delete oldest collections in a time routed
alias
Key: SOLR-11900
URL: https://issues.apache.org/jira/browse/SOLR-11900
Project: Solr
Issue Type: Sub-task
Security Level: Public (Default Security Level. Issues are Public)
Components: SolrCloud
Reporter: David Smiley
Assignee: David Smiley
Fix For: 7.3
For Time Routed Aliases, we'll need an API command to delete the oldest
collection(s). Perhaps the command action name is
DELETE_COLLECTION_OF_ROUTED_ALIAS (yes that's long). And input is of course
the routed alias name, plus a mandatory "before" which is a standard time input
that Solr accepts that will likely include date math. Thus if you used
before="NOW/DAY-90DAYS" then your guaranteed to have the last 90 days worth of
data. If a collection overlaps past what "before" is computed to be then it
needs to stay. The pattern might match any number of collections, perhaps
none. But in all cases, the most recent collection must be retained -- the
time routed aliases must at all times refer to at least one collection.
The underlying steps will be to first update the alias, and then delete the
collection(s). It ought to return the collections that get deleted.
