-------------------------------------
Thank you, [~julianhyde]! Any chance to get it in 1.4 release?
> Pre-populated materializations
> ------------------------------

> Key: CALCITE-761
> URL: https://issues.apache.org/jira/browse/CALCITE-761
> Project: Calcite
> Issue Type: Bug
> Reporter: Julian Hyde
> Assignee: Julian Hyde
> Fix For: 1.4.0-incubating
>
> Attachments: CALCITE-761-branch.patch
>
>
> The design for materializations (materialized views) allows for them to be
> populated on demand (e.g. as an ArrayTable) the first time that the
> materialization is needed or to already exist, having been populated by the
> user.
> According to [~maryannxue] the latter case does not work. Calcite tries to
> create a new table with the same name as the current table, then makes the
> name unique by adding a digit, then goes ahead and populates it.
> We need to (a) allow such materializations to be defined in the JSON model,
> (b) document how to define them, (c) make them work, (d) add tests.
> Cc [~jamestaylor], as this is related to optimization for Phoenix secondary
> indexes.
