marklogic data hub upgrade

Fixes #582 - should be reviewed for UX before merging.

DHFPROD-1726: "Update a Hub Project link" produces error, Update modules count after addition of 5.x modules, DHFPROD-1754 + other issues - develop branch, DHFPROD-1740, Create 5.x FlowManager and refactor 4.x FlowManager to LegacyFlowManager, DHFPROD-1710 - create space for the new dhf5 code (still rewriting to, DHFPROD-1751 - update develop snapshot version, Develop bug fixes related to LoadUserArtifactsCommand, Fix LoadUserArtifactsCommand and tests in 4.x, Loading to staging schemas db from database-specific directory in develop, Revert "DHFPROD-1428: Improve the usability of text input elements", DHFPROD-1428: Improve the usability of text input elements, E2e/no toaster wait -- comment out waiting for toaster after updating index, Updated tests to exclude those that are bound to fail in DHS, DHFPROD-1427 - Improve the usability of switch elements, Calling hubInstallModules in Installer class when running tests in DHS, Create 'LoadUserArtifactsCommand' for loading entities, mappings, Updating gradle-dhs.properties to run DHF core tests in DHS, Feature: Swagger powered mock api framework, Better handling of nested objects as properties when property is not defined as a formal entity, array, or scalar value, mlDeployDatabases ignores config files under entity-config, mlWatch doesn't load from src/main/ml-modules, certificate-templates and external-security config not being deployed from ml-config, DHF 4.0.0: mlDeployDatabases not deploying config from src/main/ml-config (same for mlDeploySecurity), DHF 4.0.0: mlDeploy fails (in some conditions) if project contains REST extension in ml-config, Modules location and deployment in DHF400, hubinit task should create a "stub" gradle-local.properties, Require workaround for deploying flexrep for data-hub-FINAL, if you call your mapping "mapping", it doesn't work (v4.1.0), If you call your input flow "input", it doesn't work (v4.1.0), If you call your harmonize flow "harmonize", it doesn't work (v4.1.0), Adding server namespaces in final-server.json breaks redeployment, mlLoadSchemas only loads to data-hub-staging-SCHEMAS. When exception is thrown, not all flow traces are persisted. Cooling body suit inside another insulated suit.

Thanks for contributing an answer to Stack Overflow! These can be thought of as streaming flows, in that the flow is applied to a document between an external process sending a document and MarkLogic persisting it.

Wed need to write this flow for each of the input sources, assuming that the property would be found in different places in the various sources, but this would require very little coding. If its required to manually re-create everything as steps etc in the new 5.2.x Data Hub version, this could be a large amount of work for developers. [DHFPROD-6337] - Fix RunFlowWithCustomHubConfig in dh-5-example project. adding support for input and canonical in the dir tree, Added user plugin directory in setting up Data Hub, #24 - adding the backend code to support deploying a user's modules, Quick-start Flows and Collectors backend changes and minimal main page changes, Quick start tomcat deployment and initial page. [DHFPROD-6162] - Writing temporal documents to temporal collections fails with "data-hub-operator".

These are helpful when the process of building envelopes is less straightforward.

So if an input flow can write the harmonized data to the final database, why do we need harmonize flows?

Harmonize flows are a process in themselves.

Allow Ingest to feed directly to conform w/o storing data, Auto Generate Indexes based on entity defs, Allow Exploration on the staged, raw data, display a "Loading" message while retrieving entities, disabled frame options in quickstart so it can be run inside an iframe, gradle version check fails on multiple dots, QuickStart Template Compile Error 2.0-alpha.2, customize session name to avoid conflicts, Change Java Client API dependency to stable build, Entities and custom modules fail to deploy - v1.1.0, See if we can bail if the gradle version is too low, Unable to login marklogic using hub frame work received "500 Internal Server Error", Bug: QuickStart Login screen: Long paths aren't completely visible in Chrome, Updates Java Client API dependency to stable build, Allow exernal data to be passed in to a flow's options-map, Returning json:object() isn't invoking ES serialization in flow, "No message available" when following Quick Start, if MarkLogic is not started, login reports "invalid username or password", Need gradle variables for Auth method for final, staging, etc, Investigating slow performance in loading modules on Windows, Input Flow - Output URI replace configuration doesn't stick on windows, Keep user database settings separate from hub database settings, Create a non-admin user for doing hub stuff, mlcp load from QuickStart GUI not loading data, Tutorial instruction - create entity "Employees" instead of "Employee", mlcp job is not getting run + console log button not showing, Redeploy button is wiping out hub modules, Provide Build instructions for developers, DeployViewSchemasCommand is failing installs, File change watcher fires multiple times on Windows, Clean Target database directory ? Does China receive billions of dollars of foreign aid and special WTO status for being a "developing country"? The reason to shift to a DHF 5 flow is if/when you find value in the OOTB steps - specifically mapping, matching, and merging. on Software Development and Entrepreneurism, Operational Data Hub: What It Is, Why It Came About, Using the MarkLogic Data Hub Framework (free hands-on training course), category (technical blog post, tutorial, recipe, guide, etc. Need to specify collation in query in trace-lib.xqy, fixing bug in restoring previous load options, Changes to fix JS errors in Swagger UI in master, File permission error running hadoop to do data load, Errors only flash on the GUI for a short time, Investigate MLCP UI for creating MLCP cmd line options, DataHub.installUserModules should be "syncUserModules", 192 - Removed automatic closing of notification, Handle duplicate REST service extensions and transforms. I like the term streaming instead of real-time, to avoid confusion with real-time computing. I am migrating from Data Hub 4.1.x up to 5.2.x , and was hoping its possible to run scripts to convert existing 4.1.x standard ingestion & harmonization flows into equivalent ingestion & mapping 5.2.x steps. [DHFPROD-2780] - The parameter "-output_collections" of MLCP command in the ingest step, needs to be updated. My colleague at MarkLogic, Paxton Hare, started the MarkLogic Data Hub Framework project early in 2016.

They were originally called harmonize flows because this was often the stage where documents were copied from the staging database to final, harmonizing some properties along the way. The flow then transforms and writes each document in turn. Is it possible to turn rockets without fuel just like in KSP. What is the purpose of overlapping windows in acoustic signal processing? Asking for help, clarification, or responding to other answers. Does this mean that the Final database data model should be unchanged by the upgrade as well? get_content transform not working for json files, for hl7 example change patientRecord to Patient, fixed #152 - get_content transform not working for json, fixed #146 - don't reset user prefs on logout, 142 - Add default collections when loading data using flows, fixed #140 - vet plugins not working correctly, fixed #137 - renamed patientrecords to Patients, fixed #135 - create conformance flow not working, fixed #91 - check plugins during install for errors, Add staging and final REST port as input during login, remove explicit references to "hub in a box" and use "dhib", When inserting a document from java, allow a flow to run, 117 - Add staging and final REST ports in login page, #114 - Return the updated state after deploying the modules to remove the delay, changes on the REST directory are now detected, Updated "in-a-box" to "data-hub" and "data-hub-in-a-box" to "data-hub", Misleading stack trace about missing get-content.xml, Add ability to specify some MLCP attributes on import, Add a button to deploy a User's hub modules, Allow user to specify where local hub modules are located, Allow the user to provide ML config info in a properties file or command line, Determine whether or not hub is installed immediately after login, Standard Rest transform to get content only, Update dir tree to reflect where REST stuff lives, Prompt user to determine if they want sjs or xquery plugins, Scaffolding should distinguish between input and conformance flows, As a user I want to be able to cancel a running flow because I just want to do it for the lulz, path for conformance plugins is wrong in xquery, Need UI feedback when performing long-running tasks, Update QuickStart to use Scaffolding class from data-hub jar, Make the Input and Canonical flows optional, Fix Hub Install and Uninstall in DataHub class. A harmonize flow can break it up in separate documents and populate the envelope properties (URL, category, and so on).

The first step of a harmonize flow is identifying which identifiers it will work on.

The doco seems to suggest this may be the only option. Measurable and meaningful skill levels for developers, San Francisco? Consider sending data to the staging database and then using a harmonize flow to bring it to the final database if you have any of the following situations: A harmonize flow doesnt have to move content from one database to another; it can also be used to update content in place. Making statements based on opinion; back them up with references or personal experience.

Bugfixes, issues with truncation and mime types removal. I came up with the following: Each data source can construct an input flow to build an envelope, with the original content stored in an attachments XML element or JSON property, and the above properties expressed under an instance element or property.

Is gauge covariant derivative an ordinary covariant derivative? When flying from Preclearance airports to the US, do airlines validate your visa before letting you talk to Preclearance agents? Was Mister Kitson and/or the planet of Kitson based on/named after George Kitson?

We can write a harmonize flow that bothreads from andwrites to the final content database.

Once gathered into a single database, a search service on that database would make discovery of available material across those sites much easier.

I learned some useful things about working with the framework that I thought were worth writing down (partly so that Ill remember them). Tutorial Documentation: Wrong Product Ingest folder?

The Data Hub Framework goes a long way to simplify the process of building an operational data hub. This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository. Find centralized, trusted content and collaborate around the technologies you use most. Once weve updated the input flows, how do we know which documents need the harmonize update?

That's correct, you can continue to run DHF 4 flows, which are referred to as "legacy flows".

Would it be legal to erase, disable, or destroy your phone when a border patrol agent attempted to seize it? Why do many kick scooters have such small wheels? Input flows have no writer, because the flow itself is not responsible for persisting the data. DHFPROD-730 update content to instance in docs, DHFPROD-496 update tutorial documentation for 3.x, Fixing Issue #440: Adding example w/ gradle props, Data hub job status/error popup word wrap change, DHFPROD-496 add let variable declarations, Fixing Issue #578: Adding deletion dialog, Ignore mlcp test.

Paxton once told me that he thought about naming the types of flows differently: instead of input and harmonize flows, he thought real-time and batch would better describe what they do.
