From a6b8fc27f0acb85f440e3ef5fbde22ff51243b46 Mon Sep 17 00:00:00 2001 From: Rahul Yadav Date: Thu, 8 Jan 2026 08:44:29 +0530 Subject: [PATCH 1/3] feat: add SsFormat encoding library This commit adds the foundational SsFormat class that provides sortable string format (ssformat) encoding utilities. This encoding is used by Spanner for key ordering and routing. Key features: - Composite tag encoding for interleaved tables - Signed/unsigned integer encoding (increasing/decreasing) - String and bytes encoding with proper escaping - Double encoding with proper sign handling - Timestamp and UUID encoding - Null value markers with configurable ordering - TargetRange class for key range representation Includes unit tests for all encoding functions. This is part of the experimental location-aware routing for improved latency. --- .../google/cloud/spanner/spi/v1/SsFormat.java | 374 ++++++++++++++++++ .../cloud/spanner/spi/v1/TargetRange.java | 54 +++ .../cloud/spanner/spi/v1/SsFormatTest.java | 251 ++++++++++++ 3 files changed, 679 insertions(+) create mode 100644 google-cloud-spanner/src/main/java/com/google/cloud/spanner/spi/v1/SsFormat.java create mode 100644 google-cloud-spanner/src/main/java/com/google/cloud/spanner/spi/v1/TargetRange.java create mode 100644 google-cloud-spanner/src/test/java/com/google/cloud/spanner/spi/v1/SsFormatTest.java diff --git a/google-cloud-spanner/src/main/java/com/google/cloud/spanner/spi/v1/SsFormat.java b/google-cloud-spanner/src/main/java/com/google/cloud/spanner/spi/v1/SsFormat.java new file mode 100644 index 0000000000..67ed2b3e39 --- /dev/null +++ b/google-cloud-spanner/src/main/java/com/google/cloud/spanner/spi/v1/SsFormat.java @@ -0,0 +1,374 @@ +/* + * Copyright 2026 Google LLC + * + * Licensed under the Apache License, Version 2.0 (the "License"); + * you may not use this file except in compliance with the License. + * You may obtain a copy of the License at + * + * http://www.apache.org/licenses/LICENSE-2.0 + * + * Unless required by applicable law or agreed to in writing, software + * distributed under the License is distributed on an "AS IS" BASIS, + * WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. + * See the License for the specific language governing permissions and + * limitations under the License. + */ + +package com.google.cloud.spanner.spi.v1; + +import com.google.protobuf.ByteString; +import java.io.ByteArrayOutputStream; +import java.nio.charset.StandardCharsets; + +public final class SsFormat { + + /** + * Makes the given key a prefix successor.

Key components: - KeyRecipe: Translates requests to ssformat keys using server-provided recipes - KeyRecipeCache: Caches recipes by request fingerprint for efficient reuse - PreparedRead: Helper class for preparing read requests with routing info - RecipeGoldenTest: Golden tests for recipe encoding validation - RecipeTestCases: Test case definitions for recipe tests This is part of the experimental location-aware routing for improved latency. --- .../cloud/spanner/spi/v1/KeyRecipe.java | 814 ++++ .../cloud/spanner/spi/v1/KeyRecipeCache.java | 203 + .../spanner/spi/v1/RecipeGoldenTest.java | 411 ++ .../cloud/spanner/spi/v1/RecipeTestCases.java | 247 ++ .../src/test/resources/recipe_test.textproto | 3943 +++++++++++++++++ 5 files changed, 5618 insertions(+) create mode 100644 google-cloud-spanner/src/main/java/com/google/cloud/spanner/spi/v1/KeyRecipe.java create mode 100644 google-cloud-spanner/src/main/java/com/google/cloud/spanner/spi/v1/KeyRecipeCache.java create mode 100644 google-cloud-spanner/src/test/java/com/google/cloud/spanner/spi/v1/RecipeGoldenTest.java create mode 100644 google-cloud-spanner/src/test/java/com/google/cloud/spanner/spi/v1/RecipeTestCases.java create mode 100644 google-cloud-spanner/src/test/resources/recipe_test.textproto diff --git a/google-cloud-spanner/src/main/java/com/google/cloud/spanner/spi/v1/KeyRecipe.java b/google-cloud-spanner/src/main/java/com/google/cloud/spanner/spi/v1/KeyRecipe.java new file mode 100644 index 0000000000..912a39c703 --- /dev/null +++ b/google-cloud-spanner/src/main/java/com/google/cloud/spanner/spi/v1/KeyRecipe.java @@ -0,0 +1,814 @@ +/* + * Copyright 2026 Google LLC + * + * Licensed under the Apache License, Version 2.0 (the "License");
