QUESTION

Solr: Normalize date field

Asked 2018-May-31 at 11:53

I am new to apache solr and exploring some use cases that could potentially be applicable for my application. In one of the use case, I have multiple mongodb instances pushing data to solr via mongo-connector. I am able to do so by running two instance of mongo-connector with two different mongo instance and using same solr core.

My question is: How do I handle a situation where I have a field in mongo-collection, say "startTime" which is of Date type in one mongo instance and another is treating it as long. I want this field to be treated as long type in solr. Does solr provide any sort of auto conversion or I will have to write my analyzer?

If you want both values to normalize to the same form, you should do that in the UpdateRequestProcessor (defined in solrconfig.xml). There is quite a number of them for various purposes, including date parsing. In fact, the schemaless mode is implemented by a chain of URPs, so that's an example you can review.

To process different Mongo instances in different ways, you can just define separate Update Request Handler endpoints (in solrconfig.xml again) and setup different processing for those. Use shared definitions to avoid duplicating what's common (using processor reference as in the schemaless definition linked above).

It may be more useful to normalize to dates rather than back from dates, as Solr allows more interesting searches that way, such as Date Math.

QUESTION

Meteor MongoDB subscription delivering data in 10 second intervals instead of live

Asked 2018-Jan-22 at 14:43

I believe this is more of a MongoDB question than a Meteor question, so don't get scared if you know a lot about mongo but nothing about meteor.

Running Meteor in development mode, but connecting it to an external Mongo instance instead of using Meteor's bundled one, results in the same problem. This leads me to believe this is a Mongo problem, not a Meteor problem.

The actual problem

I have a meteor project which continuosly gets data added to the database, and displays them live in the application. It works perfectly in development mode, but has strange behaviour when built and deployed to production. It works as follows:

A tiny script running separately collects broadcast UDP packages and shoves them into a mongo collection
The Meteor application then publishes a subset of this collection so the client can use it
The client subscribes and live-updates its view

The problem here is that the subscription appears to only get data about every 10 seconds, while these UDP packages arrive and gets shoved into the database several times per second. This makes the application behave weird

It is most noticeable on the collection of UDP messages, but not limited to it. It happens with every collection which is subscribed to, even those not populated by the external script

Querying the database directly, either through the mongo shell or through the application, shows that the documents are indeed added and updated as they are supposed to. The publication just fails to notice and appears to default to querying on a 10 second interval

Meteor uses oplog tailing on the MongoDB to find out when documents are added/updated/removed and update the publications based on this

Anyone with a bit more Mongo experience than me who might have a clue about what the problem is?

For reference, this is the dead simple publication function

It's a DDP (Websocket ) heartbeat configuration.

Meteor real time communication and live updates is performed using DDP ( JSON based protocol which Meteor had implemented on top of SockJS ). Client and server where it can change data and react to its changes.

DDP (Websocket) protocol implements so called PING/PONG messages (Heartbeats) to keep Websockets alive. The server sends a PING message to the client through the Websocket, which then replies with PONG.

By default heartbeatInterval is configure at little more than 17 seconds (17500 milliseconds).

Check here: https://github.com/meteor/meteor/blob/d6f0fdfb35989462dcc66b607aa00579fba387f6/packages/ddp-client/common/livedata_connection.js#L54

You can configure heartbeat time in milliseconds on server by using:
