-------------------------------------------------------------
[~chetanm], can you please review the [script|^IndexImportScript.groovy].
I've verified that this works for a import of single index (although, the code
should work in general... I just tested with one) on an AEM setup with oak
1.6.1.
Notable difference from oak-run IndexImporter in 1.8 branch:
* purges {{:data}} and {{:status}} before import
* only imports {{:data}} node
* indexes all indices in a single temp lane
TODO:
* verify with import of oob-reindex-of-multiple-indices
* verify with older branches
** IndexDefinition ctor in 1.4 (and older too I guess) doesn't take index-path
Rough sketch of process to use:
# Create a checkpoint on a running instance
# Use this checkpoint to reindex using oak-run index command
# Run attached script with path of oob-indexed-data-path in Osgi script console

> Key: OAK-6453
> URL: https://issues.apache.org/jira/browse/OAK-6453
> Project: Jackrabbit Oak
> Issue Type: Improvement
> Components: indexing, run
> Reporter: Chetan Mehrotra
> Assignee: Vikas Saurabh
> Labels: docs-impacting
> Fix For: 1.8
>
> Attachments: IndexImportScript.groovy
>
>
> The indexing tooling implemented in OAK-6081 can be used to perform reindex
> and import the indexes for any Oak 1.7+ setups. For older setups we would be
> using 2 phase approach
> # Perform [out-of-band
> indexing|https://jackrabbit.apache.org/oak/docs/query/oak-run-indexing.html#out-of-band-indexing].
> This can be done via oak-run from 1.7.x against any older version of Oak
> # Import index - For this step we cannot use oak-run from trunk for older
> branches as write operations would not be compatible with older version of
> Oak.
> For import then we have 2 options either
> # backport all the work in OAK-6271 to older branch
> # OR implement a script which can be used with oak-run or Felix Script
> Console to just import the lucene index with any other manual step
> Purpose of this task is to implement such a script
