From 412d8d597511122f114d69a4ba64c6b55dd192f9 Mon Sep 17 00:00:00 2001 From: Fabian Mastenbroek Date: Fri, 29 Apr 2022 12:09:51 +0200 Subject: feat(trace/calcite): Add Calcite (SQL) integration This change adds support for querying workload trace formats implemented using the OpenDC API through Apache Calcite. This allows users to write SQL queries to explore the workload traces. --- .../kotlin/org/opendc/trace/calcite/CalciteTest.kt | 121 +++++++++++++++++++++ .../opendc/trace/calcite/TraceSchemaFactoryTest.kt | 78 +++++++++++++ .../test/resources/trace/interference-model.json | 20 ++++ .../src/test/resources/trace/meta.parquet | Bin 0 -> 1679 bytes .../src/test/resources/trace/trace.parquet | Bin 0 -> 65174 bytes 5 files changed, 219 insertions(+) create mode 100644 opendc-trace/opendc-trace-calcite/src/test/kotlin/org/opendc/trace/calcite/CalciteTest.kt create mode 100644 opendc-trace/opendc-trace-calcite/src/test/kotlin/org/opendc/trace/calcite/TraceSchemaFactoryTest.kt create mode 100644 opendc-trace/opendc-trace-calcite/src/test/resources/trace/interference-model.json create mode 100644 opendc-trace/opendc-trace-calcite/src/test/resources/trace/meta.parquet create mode 100644 opendc-trace/opendc-trace-calcite/src/test/resources/trace/trace.parquet (limited to 'opendc-trace/opendc-trace-calcite/src/test') diff --git a/opendc-trace/opendc-trace-calcite/src/test/kotlin/org/opendc/trace/calcite/CalciteTest.kt b/opendc-trace/opendc-trace-calcite/src/test/kotlin/org/opendc/trace/calcite/CalciteTest.kt new file mode 100644 index 00000000..f0e461e0 --- /dev/null +++ b/opendc-trace/opendc-trace-calcite/src/test/kotlin/org/opendc/trace/calcite/CalciteTest.kt @@ -0,0 +1,121 @@ +/* + * Copyright (c) 2022 AtLarge Research + * + * Permission is hereby granted, free of charge, to any person obtaining a copy + * of this software and associated documentation files (the "Software"), to deal + * in the Software without restriction, including without limitation the rights + * to use, copy, modify, merge, publish, distribute, sublicense, and/or sell + * copies of the Software, and to permit persons to whom the Software is + * furnished to do so, subject to the following conditions: + * + * The above copyright notice and this permission notice shall be included in all + * copies or substantial portions of the Software. + * + * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR + * IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, + * FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
