Please, add more info. Probably, describe a user story with this feature implemented: plugin for plugin case. It also add dependency clean up and extensibility.

Describe:
- discovered DS interfaces, for example:
parse
for UDFparse
for identifier- analyze, optimize, etc
- API to plug/attach new DS on runtime
- how parser with UDF should work
- algorithm of resolution of a DS for a query with examples; consider tricky examples, when UDF or identifier exists in multiple DS
- override policy and workflow (in case if a DS overrides a built-in function), or if it is prohibited - how it is checked
- Query processing flow and response if UDF/identifier isn't resolved

Does this resolve the entire issue? According to opensearch-project#811 (comment), I believe this only resolves core functions. But does it also refactor the parser and pull out the push-down functions?

In other words, I think we need to list exactly what we are resolving as part of issue opensearch-project#811.

Can we name this file a bit more specifically? I think core-refactor doesn't describe the changes or objectives accurately enough.

- Using data sources other than OpenSearch, users will encounter a `SyntaxCheckException` when they query with OpenSearch specific functions. (Some of these functions can be found in https://opensearch.org/docs/latest/search-plugins/sql/sql/functions/) | ||
- The Parser will have a different token to categorize OpenSearch functions. | ||
- Core module will no longer contain OpenSearch functions. |

This is the #1 goal, right?
Everything is a by-product of getting the functions out of the core
module.

This is a architectural design element, not functional. The users won't see this, nor is this a requirement.

However, the parameter have no benefit for ip2geo processor as we don't do a sequantial search for array data but use multi search. max_concurrency and batch_size setting is removed as these are only reveal internal implementation and could be a future blocker to improve performance later. Signed-off-by: Heemin Kim <heemin@amazon.com> * Add a field in datasource for current index name (#333) Signed-off-by: Heemin Kim <heemin@amazon.com> * Delete GeoIP data indices after restoring complete (#334) We don't want to use restored GeoIP data indices. Therefore we delete the indices once restoring process complete. When GeoIP metadata index is restored, we create a new GeoIP data index instead. Signed-off-by: Heemin Kim <heemin@amazon.com> * Use bool query for array form of IPs (#335) Signed-off-by: Heemin Kim <heemin@amazon.com> * Run update/delete request in a new thread (#337) This is not to block transport thread Signed-off-by: Heemin Kim <heemin@amazon.com> * Remove IP2Geo processor validation (#336) Cannot query index to get data to validate IP2Geo processor. Will add validation when we decide to store some of data in cluster state metadata. Signed-off-by: Heemin Kim <heemin@amazon.com> * Acquire lock sychronously (#339) By acquiring lock asychronously, the remaining part of the code is being run by transport thread which does not allow blocking code. We want only single update happen in a node using single thread. However, it cannot be acheived if I acquire lock asynchronously and pass the listener. Signed-off-by: Heemin Kim <heemin@amazon.com> * Added a cache to store datasource metadata (#338) Signed-off-by: Heemin Kim <heemin@amazon.com> * Changed class name and package (#341) Signed-off-by: Heemin Kim <heemin@amazon.com> * Refactoring of code (#342) 1. Changed class name from Ip2GeoCache to Ip2GeoCachedDao 2. Moved the Ip2GeoCachedDao from cache to dao package Signed-off-by: Heemin Kim <heemin@amazon.com> * Add geo data cache (#340) Signed-off-by: Heemin Kim <heemin@amazon.com> * Add cache layer to reduce GeoIp data retrieval latency (opensearch-project#343) Signed-off-by: Heemin Kim <heemin@amazon.com> * Use _primary in query preference and few changes (opensearch-project#347) 1. Use _primary preference to get datasource metadata so that it can read the latest data. RefreshPolicy.IMMEDIATE won't refresh replica shards immediately according to #346 2. Update datasource metadata index mapping 3. Move batch size from static value to setting Signed-off-by: Heemin Kim <heemin@amazon.com> * Wait until GeoIP data to be replicated to all data nodes (opensearch-project#348) Signed-off-by: Heemin Kim <heemin@amazon.com> * Update packages according to a change in OpenSearch core (opensearch-project#354) * Update packages according to a change in OpenSearch core Signed-off-by: Heemin Kim <heemin@amazon.com> * Update packages according to a change in OpenSearch core (opensearch-project#353) Signed-off-by: Heemin Kim <heemin@amazon.com> --------- Signed-off-by: Heemin Kim <heemin@amazon.com> --------- Signed-off-by: Vijayan Balasubramanian <balasvij@amazon.com> Signed-off-by: Heemin Kim <heemin@amazon.com> Co-authored-by: Vijayan Balasubramanian <balasvij@amazon.com> Co-authored-by: mend-for-github-com[bot] <50673670+mend-for-github-com[bot]@users.noreply.github.com>
