Feature Updates

The following features updates are included in this release.

Migration to Play - Breaking Change

The previous generic global URL api-gdn.paas.macrometa.io is no longer valid.

Customers with Macrometa Play tier accounts can use api-play.paas.macrometa.io as a substitute, but we do not recommend it.

Instead, we recommend that you use an account-specific global or regional URL, which you can find in the API Reference in the Macrometa web console or on your GeoFabrics page. Any endpoint listed on the GeoFabric will accept API calls if you prepend api- to it.

For more information, refer to Unique Global URL vs. Generic.

Stream Worker Prefixes

You can now prepend a stream worker name to the aggregation tables that it creates. For example, if the stream worker name is SampleAggregationApp and the aggregation is TradeAggregation, then it will create tables like SampleAggregationApp-TradeAggregation_SECONDS. Previously, it was just TradeAggregation_SECONDS.

Auth Improvements

  • We redesigned Macrometa authorization to make our service more efficient and stable.
  • The account signup and login screens have been updated and improved.

API Updates

This release includes the following API changes.

Issue #Description
APIDOC-51Added stream worker parameters maxLogsLengthKBPerMinutePerWorker and maxCpuSecondsPerMinutePerWorker.
APIDOC-54In API reference docs, corrected a typo in insertDocument description.
DB-1692The fabric creation endpoint in the API now allows up to 40 characters for fabric names, just like in the web console.
DB-1704Clarified in the API documentation for Import API that the _key must be a string.

Import and Export Changes (DB-1660)

  • You can now export in Vpack format.
  • Added batching support for importing and exporting.

User Changes (DB-1783)

  • The user parameter is deprecated and will not be used while creating the new user. For backward compatibility, it will not generate any errors.
  • Provided a new optional parameter displayName to set the display name of the user. Whitespaces are allowed.

Here is a sample for the updated request body:

curl -X 'POST' \ 'https://api-qa6.eng.macrometa.io/_api/user' \ 
-H 'accept: application/json' \
-H 'Content-Type: application/json' \
-H 'Authorization: bearer <token> \
-d {
"active": true,
"email": "[email protected]",
"passwd": "[email protected]",
"displayName":"John Doe"
}'

Known Issues

The following known issues were introduced in this release.

Stream Workers and Query Workers are Limited to Owners

Problem: Currently the stream workers and query workers are scoped by tenant, fabric, and owner where owner is the user account that created the worker. The result of this is stream workers and query workers created by one user cannot be seen by another user belonging to same tenant and fabric.

Workaround: If you encounter this issue, then reduce the scope to tenant and fabric for the workers so that all users with permission on a GeoFabric can see the stream workers and query users regardless of which user created them.

Local Stream is Not Accessible after Upgrade from 17.10 to 17.11

Problem: Sometimes local streams are not accessible in the Macrometa console.

Workaround: If you encounter this error, then run the Publish Message API endpoint for particular stream to get rid of the issue.

POST /_fabric/_system/_api/streams/{stream}/publish

For more information about running API commands, refer to APIs.
