In System Settings - Time To Live settings, there are two sections, "Local" and "Indexing".
What are the differences?
Can you explain an use case that requires these independent settings?
Can we get a line in the help "Setting the default sliding window size for real-time trending" to document this?
Local indicates the Time To Live values that will be used for data on the SQL / Cassandra main database.
Indexing indicates the Time To Live values that will be used on the Elasticsearch database (if installed).
Some extra things to note: it's currently not possible to store trend data in the indexing database, so configuring trending TTL values there will not affect anything.
To configure how long the real time trend data is kept in the database, the Local>Trending>Realtime field should be used.
