This is similar to the Logstash +pipeline model. + +.. contents:: :backlinks: entry + +Overview +-------- + +The pipeline architecture consists of three main components: + +- **Inputs**: Define where documents come from (local filesystem, SSH, FTP, S3, HTTP) +- **Filters**: Process and transform documents (Tika parsing, JSON, XML) +- **Outputs**: Define where documents are sent (Elasticsearch) + +Each component can have multiple instances, and filters/outputs support conditional routing +using MVEL expressions. + +Backward Compatibility +---------------------- + +The legacy v1 configuration format is still fully supported. When FSCrawler loads a v1 configuration, +it automatically converts it to v2 format internally. A deprecation warning is displayed, and the +suggested v2 configuration is logged. + +To migrate your configuration manually, use the ``--migrate`` CLI option (see :ref:`cli-migrate`). + +Basic v2 Configuration +---------------------- + +Here is a simple v2 configuration example: + +.. code:: yaml + + version: 2 + name: "my_job" + + inputs: + - type: local + id: main_input + url: "/path/to/docs" + update_rate: "5m" + includes: + - "*.pdf" + - "*.docx" + + filters: + - type: tika + id: main_filter + + outputs: + - type: elasticsearch + id: main_output + urls: + - "https://127.0.0.1:9200" + index: "my_docs" + +Configuration Format +-------------------- + +Version Field +^^^^^^^^^^^^^ + +The ``version`` field indicates the configuration format version: + +.. code:: yaml + + version: 2 + +If omitted, FSCrawler will detect the format based on the presence of ``inputs``/``filters``/``outputs`` +fields (v2) or ``fs``/``server`` fields (v1). + +Inputs +^^^^^^ + +Inputs define where documents are read from.

Having two ways to do the same thing adds unnecessary complexity: - More code to maintain (normalization logic) - More documentation to write - More user confusion about which form to use - More edge cases and potential errors Changes: - Remove input/filter/output fields from FsSettings - Remove normalizeSingularToPlural() from FsSettingsMigrator - Update detectVersion() to only check plural forms - Remove singular form loading from FsSettingsLoader - Remove related unit and integration tests - Remove "Singular vs Plural Syntax" section from documentation Users should now use only the plural form (inputs/filters/outputs), which is consistent and clear. --- docs/source/admin/fs/pipeline.rst | 28 ------- .../FsCrawlerTestPipelineV2IT.java | 44 ----------- .../crawler/fs/settings/FsSettings.java | 40 +--------- .../crawler/fs/settings/FsSettingsLoader.java | 14 +--- .../fs/settings/FsSettingsMigrator.java | 52 +------------ .../fs/settings/FsSettingsMigratorTest.java | 76 ------------------- 6 files changed, 9 insertions(+), 245 deletions(-) diff --git a/docs/source/admin/fs/pipeline.rst b/docs/source/admin/fs/pipeline.rst index 9d0e55294..81acb3075 100644 --- a/docs/source/admin/fs/pipeline.rst +++ b/docs/source/admin/fs/pipeline.rst @@ -363,34 +363,6 @@ Here is a complete example with multiple inputs, conditional filters, and output index: "archive" when: "size > 10485760" # Files > 10MB go to archive -Singular vs Plural Syntax -------------------------- - -For simple configurations with a single input/filter/output, you can use the singular -form (``input``, ``filter``, ``output``) instead of lists: - -.. code:: yaml - - version: 2 - name: "simple_job" - - input: - type: local - id: main - url: "/path/to/docs" - - filter: - type: tika - id: main - - output: - type: elasticsearch - id: main - urls: - - "https://127.0.0.1:9200" - -This is equivalent to using lists with a single element. - .. _cli-migrate: Migrating from v1 to v2 diff --git a/integration-tests/src/test/java/fr/pilato/elasticsearch/crawler/fs/test/integration/elasticsearch/FsCrawlerTestPipelineV2IT.java b/integration-tests/src/test/java/fr/pilato/elasticsearch/crawler/fs/test/integration/elasticsearch/FsCrawlerTestPipelineV2IT.java index c98ae9999..80d543769 100644 --- a/integration-tests/src/test/java/fr/pilato/elasticsearch/crawler/fs/test/integration/elasticsearch/FsCrawlerTestPipelineV2IT.java +++ b/integration-tests/src/test/java/fr/pilato/elasticsearch/crawler/fs/test/integration/elasticsearch/FsCrawlerTestPipelineV2IT.java @@ -137,45 +137,6 @@ public void test_v2_yaml_generation() throws Exception { assertThat(yaml).contains("type: \"elasticsearch\"");

Fix broken :ref:`docker-options` reference in installation.rst - Changed to :ref:`cli-options` which exists 2. Sort settings files alphabetically in FsSettingsLoader - Files in _settings/ directory are now loaded in sorted order - Enables deterministic loading order with numeric prefixes 3. Add split configuration output to --migrate CLI - --migrate-output _settings/ creates split files - Files use indexed array syntax (inputs[0], inputs[1], etc.) - Numeric prefixes ensure correct loading order: - 00-common.yaml (name, version) - 10-input-*.yaml (inputs) - 20-filter-*.yaml (filters) - 30-output-*.yaml (outputs) 4. Update documentation - Add Docker examples for --migrate option - Document split file structure in pipeline.rst - Explain single file vs split output in cli-options.rst - Note about using relative paths with Docker This enables better organization of complex pipeline configurations with multiple inputs, filters, and outputs. --- .../crawler/fs/cli/FsCrawlerCli.java | 81 ++++++++-- docs/source/admin/cli-options.rst | 67 ++++++++- docs/source/admin/fs/pipeline.rst | 64 ++++++++ docs/source/installation.rst | 2 +- .../crawler/fs/settings/FsSettingsLoader.java | 8 +- .../fs/settings/FsSettingsMigrator.java | 139 ++++++++++++++++++ 6 files changed, 339 insertions(+), 22 deletions(-) diff --git a/cli/src/main/java/fr/pilato/elasticsearch/crawler/fs/cli/FsCrawlerCli.java b/cli/src/main/java/fr/pilato/elasticsearch/crawler/fs/cli/FsCrawlerCli.java index b7e9949e4..c673acbba 100644 --- a/cli/src/main/java/fr/pilato/elasticsearch/crawler/fs/cli/FsCrawlerCli.java +++ b/cli/src/main/java/fr/pilato/elasticsearch/crawler/fs/cli/FsCrawlerCli.java @@ -46,6 +46,7 @@ import java.nio.file.Paths; import java.time.Duration; import java.util.List; +import java.util.Map; import java.util.Scanner; import static fr.pilato.elasticsearch.crawler.fs.framework.FsCrawlerUtil.*; @@ -418,32 +419,82 @@ private static void migrateConfiguration(Path configDir, String jobName, String // Perform the migration FsSettings v2Settings = FsSettingsMigrator.migrateV1ToV2(fsSettings); - // Generate the v2 YAML - String v2Yaml = FsSettingsMigrator.generateV2Yaml(v2Settings); - if (outputFile != null) { - // Write to output file - Path outputPath = Paths.get(outputFile); - if (!outputPath.isAbsolute()) { - outputPath = configDir.resolve(jobName).resolve(outputFile); + // Check if output should be a split directory structure + boolean isSplitOutput = outputFile.endsWith("/") || + outputFile.equals(FsSettingsLoader.SETTINGS_DIR) || + outputFile.endsWith("/" + FsSettingsLoader.SETTINGS_DIR); + + if (isSplitOutput) { + // Generate split files + writeSplitConfiguration(configDir, jobName, outputFile, v2Settings); + } else { + // Write single file + writeSingleConfiguration(configDir, jobName, outputFile, v2Settings); } - Files.writeString(outputPath, v2Yaml); - FSCrawlerLogger.console("Migrated configuration written to [{}]", outputPath); - FSCrawlerLogger.console(""); - FSCrawlerLogger.console("To use the new configuration:"); - FSCrawlerLogger.console(" 1.
