A high level description of how it works is that there are two separate +processes in place, one for writing data in disk, and one for reading/exporting the previously +stored data. + +* Each exporter stores the received data automatically in disk right after it's received from its + processor. +* The reading of the data back from disk and exporting process has to be done manually.

There's more information on it can be + achieved, under [Reading data](#reading-data). + +> For a more detailed information on how the whole process works, take a look at +> the [CONTRIBUTING](CONTRIBUTING.md) file. + +## Configuration + +The configurable parameters are provided **per exporter**, the available ones are: + +* Max file size, defaults to 1MB. +* Max folder size, defaults to 10MB. All files are stored in a single folder per-signal, therefore + if all 3 types of signals are stored, the total amount of space from disk to be taken by default + would be of 30MB. +* Max age for file writing, defaults to 30 seconds. +* Min age for file reading, defaults to 33 seconds. It must be greater that the max age for file + writing. +* Max age for file reading, defaults to 18 hours. After that time passes, the file will be + considered stale and will be removed when new files are created. No more data will be read from a + file past this time. +* An instance + of [TemporaryFileProvider](src/main/java/io/opentelemetry/contrib/disk/buffering/internal/files/TemporaryFileProvider.java), + defaults to calling `File.createTempFile`. This provider will be used when reading from the disk + in order create a temporary file from which each line (batch of signals) will be read and + sequentially get removed from the original cache file right after the data has been successfully + exported. + +## Usage + +### Storing data + +In order to use it, you need to wrap your own exporter with a new instance of +the ones provided in here: + +* For a LogRecordExporter, it must be wrapped within + a [LogRecordDiskExporter](src/main/java/io/opentelemetry/contrib/disk/buffering/LogRecordDiskExporter.java). +* For a MetricExporter, it must be wrapped within + a [MetricDiskExporter](src/main/java/io/opentelemetry/contrib/disk/buffering/MetricDiskExporter.java). +* For a SpanExporter, it must be wrapped within + a [SpanDiskExporter](src/main/java/io/opentelemetry/contrib/disk/buffering/SpanDiskExporter.java). + +Each wrapper will need the following when instantiating them: + +* The exporter to be wrapped. +* A File instance of the root directory where all the data is going to be written. The same root dir + can be used for all the wrappers, since each will create their own folder inside it. +* An instance + of [StorageConfiguration](src/main/java/io/opentelemetry/contrib/disk/buffering/internal/StorageConfiguration.java) + with the desired parameters. You can create one with default values by + calling `StorageConfiguration.getDefault()`. + +After wrapping your exporters, you must register the wrapper as the exporter you'll use. It will +take care of always storing the data it receives. + +#### Set up example for spans + +```java +// Creating the SpanExporter of our choice. +SpanExporter mySpanExporter = OtlpGrpcSpanExporter.getDefault(); + +// Wrapping our exporter with its disk exporter. +SpanDiskExporter diskExporter = SpanDiskExporter.create(mySpanExporter, new File("/my/signals/cache/dir"), StorageConfiguration.getDefault()); + + // Registering the disk exporter within our OpenTelemetry instance. +SdkTracerProvider myTraceProvider = SdkTracerProvider.builder() + .addSpanProcessor(SimpleSpanProcessor.create(diskExporter)) + .build(); +OpenTelemetrySdk.builder() + .setTracerProvider(myTraceProvider) + .buildAndRegisterGlobal(); + +``` + +### Reading data + +Each of the exporter wrappers can read from the disk and send the retrieved data over to their +wrapped exporter by calling this method from them: + +```java +try { + if(diskExporter.exportStoredBatch(1, TimeUnit.SECONDS)) { + // A batch was successfully exported and removed from disk. You can call this method for as long as it keeps returning true. + } else { + // Either there was no data in the disk or the wrapped exporter returned CompletableResultCode.ofFailure(). + } +} catch (IOException e) { + // Something unexpected happened. +} +``` + +Both the writing and reading processes can run in parallel and they don't overlap +because each is supposed to happen in different files. We ensure that reader and writer don't +accidentally meet in the same file by using the configurable parameters. These parameters set non-overlapping time frames for each action to be done on a single file at a time. On top of that, there's a mechanism in +place to avoid overlapping on edge cases where the time frames ended but the resources haven't been +released. For that mechanism to work properly, this tool assumes that both the reading and the +writing actions are executed within the same application process. + +## Component owners + +- [Cesar Munoz](https://github.com/LikeTheSalad), Elastic +- [Gregor Zeitlinger](https://github.com/zeitlinger), Grafana + +Learn more about component owners in [component_owners.yml](../.github/component_owners.yml). diff --git a/disk-buffering/assets/reading-flow.png b/disk-buffering/assets/reading-flow.png new file mode 100644 index 000000000..76b8de438 Binary files /dev/null and b/disk-buffering/assets/reading-flow.png differ diff --git a/disk-buffering/assets/writing-flow.png b/disk-buffering/assets/writing-flow.png new file mode 100644 index 000000000..c6144b301 Binary files /dev/null and b/disk-buffering/assets/writing-flow.png differ diff --git a/disk-buffering/build.gradle.kts b/disk-buffering/build.gradle.kts new file mode 100644 index 000000000..2be29ccc9 --- /dev/null +++ b/disk-buffering/build.gradle.kts @@ -0,0 +1,50 @@ +import ru.vyarus.gradle.plugin.animalsniffer.AnimalSniffer + +plugins { + id("otel.java-conventions") + id("otel.publish-conventions") + id("me.champeau.jmh") version "0.7.1" + id("ru.vyarus.animalsniffer") version "1.7.1" +} + +description = "Exporter implementations that store signals on disk" +otelJava.moduleName.set("io.opentelemetry.contrib.exporters.disk") + +java { + sourceCompatibility = JavaVersion.VERSION_1_8 + targetCompatibility = JavaVersion.VERSION_1_8 +} + +val autovalueVersion = "1.10.2" +dependencies { + api("io.opentelemetry:opentelemetry-sdk") + implementation("io.opentelemetry:opentelemetry-exporter-otlp-common") + implementation("io.opentelemetry.proto:opentelemetry-proto:0.20.0-alpha") + compileOnly("com.google.auto.value:auto-value-annotations:$autovalueVersion") + annotationProcessor("com.google.auto.value:auto-value:$autovalueVersion") + signature("com.toasttab.android:gummy-bears-api-24:0.5.1@signature") + testImplementation("org.mockito:mockito-inline:4.11.0") + testImplementation("io.opentelemetry:opentelemetry-sdk-testing") +} + +animalsniffer { + sourceSets = listOf(java.sourceSets.main.get()) +} + +// Always having declared output makes this task properly participate in tasks up-to-date checks +tasks.withType { + reports.text.required.set(true) +} + +// Attaching animalsniffer check to the compilation process. +tasks.named("classes").configure { + finalizedBy("animalsnifferMain") +} + +jmh { + warmupIterations.set(0) + fork.set(2) + iterations.set(5) + timeOnIteration.set("5s") + timeUnit.set("ms") +} diff --git a/disk-buffering/src/jmh/java/io/opentelemetry/contrib/disk/buffering/internal/files/utils/FileTransferUtilBenchmark.java b/disk-buffering/src/jmh/java/io/opentelemetry/contrib/disk/buffering/internal/files/utils/FileTransferUtilBenchmark.java new file mode 100644 index 000000000..a9fb7ad5e --- /dev/null +++ b/disk-buffering/src/jmh/java/io/opentelemetry/contrib/disk/buffering/internal/files/utils/FileTransferUtilBenchmark.java @@ -0,0 +1,57 @@ +/* + * Copyright The OpenTelemetry Authors + * SPDX-License-Identifier: Apache-2.0 + */ + +package io.opentelemetry.contrib.disk.buffering.internal.files.utils;
