Text query with persistence

[dkarachentsev]

Hi guys,

We have Apache Lucene based full text search that creates in-memory
indexes. It's a nice feature, but it seems absolutely useless with
persistence as indexes are dropped on node restart.

Probably we need a configuration flag and\or API call to rebuild them,
or persist somehow.

Do we have plans/ticket for that? Or maybe some tricky way to recreate
indexes?

Thanks!

Hi Dmitriy,

We do have a ticket for this [1], however, I am not sure it will be
completed any time soon.

As for the rebuilding indexes at the node startup, we already have an
internal routine for this (see GridQueryIndexing#rebuildIndexesFromHash).
The only thing we need to implement is skipping of regular indexes update
during the full-text index rebuild and maybe provide an API so that a user
can trigger this.
