Using Spark Connect (PPL Grammar To dataframe API Translation)** + +In Apache Spark 3.4, Spark Connect introduced a decoupled client-server architecture that allows remote connectivity to Spark clusters using the DataFrame API and unresolved logical plans as the protocol. + +**How Spark Connect works**: +The Spark Connect client library is designed to simplify Spark application development. It is a thin API that can be embedded everywhere: in application servers, IDEs, notebooks, and programming languages. The Spark Connect API builds on Spark’s DataFrame API using unresolved logical plans as a language-agnostic protocol between the client and the Spark driver. + +The Spark Connect client translates DataFrame operations into unresolved logical query plans which are encoded using protocol buffers. These are sent to the server using the gRPC framework. +The Spark Connect endpoint embedded on the Spark Server receives and translates unresolved logical plans into Spark’s logical plan operators. This is similar to parsing a SQL query, where attributes and relations are parsed and an initial parse plan is built. From there, the standard Spark execution process kicks in, ensuring that Spark Connect leverages all of Spark’s optimizations and enhancements. Results are streamed back to the client through gRPC as Apache Arrow-encoded row batches. + +**Advantages :** +Stability: Applications that use too much memory will now only impact their own environment as they can run in their own processes. Users can define their own dependencies on the client and don’t need to worry about potential conflicts with the Spark driver. + +Upgradability: The Spark driver can now seamlessly be upgraded independently of applications, for example to benefit from performance improvements and security fixes. This means applications can be forward-compatible, as long as the server-side RPC definitions are designed to be backwards compatible. + +Debuggability and observability: Spark Connect enables interactive debugging during development directly from your favorite IDE. Similarly, applications can be monitored using the application’s framework native metrics and logging libraries. + +Not need separating PPL into a dedicated library - all can be done from the existing SQL repository. + +**Disadvantages :** +Not all _managed_ Spark solution support this "new" feature so as part of using this capability we will need to manually deploy the corresponding spark-connect plugins as part of flint’s deployment. + +All the context creation would have to be done from the spark client - this creates some additional complexity since the Flint spark plugin has some contextual requirements that have to be somehow propagated from the client’s side . + +--- + +### Implemented solution +As presented here and detailed in the [issue](https://github.com/opensearch-project/opensearch-spark/issues/30), there are several options to allow spark to be able to understand and run ppl queries. + +The selected option is to us the PPL AST logical plan API and traversals to transform the PPL logical plan into Catalyst logical plan thus enabling a the longer term +solution for using spark-connect as a part of the ppl-client (as described below): + +Advantages of the selected approach: + +- **reuse** of existing PPL code that is tested and in production +- **simplify** development while relying on well known and structured codebase +- **long term support** in case the `spark-connect` will become user chosen strategy - existing code can be used without any changes +- **single place of maintenance** by reusing the PPL logical model which relies on ppl antlr parser, we can use a single repository to maintain and develop the PPL language without the need to constantly merge changes upstream . + +The following diagram shows the high level architecture of the selected implementation solution : + +![ppl logical architecture ](https://github.com/opensearch-project/opensearch-spark/assets/48943349/6965258f-9823-4f12-a4f9-529c1365fc4a) + +The **logical Architecture** show the next artifacts: +- **_Libraries_**: + - PPL ( the ppl core , protocol, parser & logical plan utils) + - SQL ( the SQL core , protocol, parser - depends on PPL for using the logical plan utils) + +- **_Drivers_**: + - PPL OpenSearch Driver (depends on OpenSearch core) + - PPL Spark Driver (depends on Spark core) + - PPL Prometheus Driver (directly translates PPL to PromQL ) + - SQL OpenSearch Driver (depends on OpenSearch core) + +**Physical Architecture :** +Currently the drivers reside inside the PPL client repository within the OpenSearch Plugins. +Next tasks ahead will resolve this: + +- Extract PPL logical component outside the SQL plugin into a (none-plugin) library - publish library to maven +- Separate the PPL / SQL drivers inside the OpenSearch PPL client to better distinguish +- Create a thin PPL client capable of interaction with the PPL Driver regardless of which driver (Spark , OpenSearch , Prometheus ) + + +### Roadmap + +This section describes the next steps planned for enabling additional commands and gamer translation. \ No newline at end of file diff --git a/ppl-spark-integration/src/main/java/org/opensearch/sql/ast/dsl/AstDSL.java b/ppl-spark-integration/src/main/java/org/opensearch/sql/ast/dsl/AstDSL.java deleted file mode 100644 index 1eb422d2f..000000000 --- a/ppl-spark-integration/src/main/java/org/opensearch/sql/ast/dsl/AstDSL.java +++ /dev/null @@ -1,420 +0,0 @@ -/* - * Copyright OpenSearch Contributors - * SPDX-License-Identifier: Apache-2.0 - */ - -package org.opensearch.sql.ast.dsl;
