follow up on same question on #1600.
why it is abstract and no subclass?

The subclass is created in OpenSearchIndex.createScanBuilder
. The subclass captures data (primarily OpenSearch client reference) necessary in OpenSearchIndexScanBuilder.build
to create an instance of OpenSearchIndexScan
.
At this point, OpenSearchIndexScanBuilder
can become an inner class of OpenSearchIndex
but doing so includes refactoring of OpenSearchIndexScanOptimizationTest suite as well.
I plan to include this change as part of follow-up pagination work.
This was my response in #1600 with a slightly different description.

OpenSearchIndexScanBuilder.createScan
-- create an OpenSearchIndexScan based on the provided OpenSearchRequest.
OpenSearchIndexScanBuilder.build
-- build an OpenSearchRequest and an OpenSearchIndexScan based on it.
They will be merged as part of making OpenSearchIndexScanBuilder
inner class of OpenSearchIndexScan
.

Observation: there are about 15 files with no-op changes - whitespaces or comment updating. Pagination feature had bigger scope, but after few rounds of reworks and improvements, some changes were reverted, but not comments.
I also found few typos in javadocs, nothing critical. Will be fixed in the following work on Pagination feature.
No issues nor objections found while code review and manual testing!

Description
v2 SQL engine can now paginate simple queries. Pagination is initiated by setting
fetch_size
property in the request JSON.For example, initiate a pagination request, send:
Send the following to get a subsequent page:
Each response to a pagination request will include a
cursor
property if there is more data available. The last page in the paginated request will not have acursor
property.Pagination is implemented using the OpenSearch Scroll API. Please see pagination-v2.md for implementation details.
