From 7409fb41bdafff93ade4e83603d697315409e0fa Mon Sep 17 00:00:00 2001 From: Ryan Nicholson Date: Fri, 21 Aug 2020 17:32:46 -0700 Subject: [PATCH 001/248] [FlightRPC] Flight SQL POC MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add extensions in the Apache Arrow project’s Arrow Flight modules to provide a standard way for clients and servers to communicate with SQL-like semantics. Do not pull to master. A message to the mailing list will accompany this and another proposal in the coming days for discussion. --- format/FlightSQL.proto | 226 +++++++ .../arrow/flight/FlightRuntimeException.java | 2 +- java/flight/flight-sql/pom.xml | 178 ++++++ .../flight/sql/FlightSQLClientUtils.java | 219 +++++++ .../arrow/flight/sql/FlightSQLProducer.java | 339 ++++++++++ .../arrow/flight/sql/FlightSQLUtils.java | 203 ++++++ .../apache/arrow/flight/TestFlightSQL.java | 262 ++++++++ .../arrow/flight/sql/FlightSQLExample.java | 601 ++++++++++++++++++ .../flight/sql/PreparedStatementCacheKey.java | 83 +++ .../flight/sql/PreparedStatementContext.java | 65 ++ .../src/test/protobuf/flightSQLExample.proto | 26 + java/pom.xml | 1 + 12 files changed, 2204 insertions(+), 1 deletion(-) create mode 100644 format/FlightSQL.proto create mode 100644 java/flight/flight-sql/pom.xml create mode 100644 java/flight/flight-sql/src/main/java/org/apache/arrow/flight/sql/FlightSQLClientUtils.java create mode 100644 java/flight/flight-sql/src/main/java/org/apache/arrow/flight/sql/FlightSQLProducer.java create mode 100644 java/flight/flight-sql/src/main/java/org/apache/arrow/flight/sql/FlightSQLUtils.java create mode 100644 java/flight/flight-sql/src/test/java/org/apache/arrow/flight/TestFlightSQL.java create mode 100644 java/flight/flight-sql/src/test/java/org/apache/arrow/flight/sql/FlightSQLExample.java create mode 100644 java/flight/flight-sql/src/test/java/org/apache/arrow/flight/sql/PreparedStatementCacheKey.java create mode 100644 java/flight/flight-sql/src/test/java/org/apache/arrow/flight/sql/PreparedStatementContext.java create mode 100644 java/flight/flight-sql/src/test/protobuf/flightSQLExample.proto diff --git a/format/FlightSQL.proto b/format/FlightSQL.proto new file mode 100644 index 00000000000..2ef7299becb --- /dev/null +++ b/format/FlightSQL.proto @@ -0,0 +1,226 @@ +/* + * Licensed to the Apache Software Foundation (ASF) under one + * or more contributor license agreements.
