Apache Kafka

Despite the disadvantages I list, I really believe that Kafka is the right choice whenever you need a queueing or message broker system. Kafka is way too battle-tested and scales too well to ever not consider it. The only exception is if your use case requires many, many small topics. Also, Kafka doesn't support delay queues out of the box and so you will need to "hack" it through special code on the consumer side.

Apache Solr

Solr spins up nicely and works effectively for small enterprise environments providing helpful mechanisms for fuzzy searches and facetted searching. For larger enterprises with complex business solutions you'll find the need to hire an expert Solr engineer to optimize the powerful platform to your needs.Internationalization is tricky with Solr and many hosting solutions may limit you to a latin character set.

Pros

Apache Kafka

  • Apache Kafka is able to handle a large number of I/Os (writes) using 3-4 cheap servers.
  • It scales very well over large workloads and can handle extreme-scale deployments (eg. Linkedin with 300 billion user events each day).
  • The same Kafka setup can be used as a messaging bus, storage system or a log aggregator making it easy to maintain as one system feeding multiple applications.

Apache Solr

  • Easy to get started with Apache Solr. Whether it is tackling a setup issue or trying to learn some of the more advanced features, there are plenty of resources to help you out and get you going.
  • Performance. Apache Solr allows for a lot of custom tuning (if needed) and provides great out of the box performance for searching on large data sets.
  • Maintenance. After setting up Solr in a production environment there are plenty of tools provided to help you maintain and update your application. Apache Solr comes with great fault tolerance built in and has proven to be very reliable.

Cons

Apache Kafka

  • Still a bit inmature, some clients have required recoding in the last few versions
  • New feaures coming very fast, several upgrades a year may be required
  • Not many commercial companies provide support

Apache Solr

  • These examples are due to the way we use Apache Solr. I think we have had the same problems with other NoSQL databases (but perhaps not the same solution). High data volumes of data and a lot of users were the causes.
  • We have lot of classifications and lot of data for each classification. This gave us several problems:
  • First: We couldn't keep all our data in Solr. Then we have all data in our MySQL DB and searching data in Solr. So we need to be sure to update and match the 2 databases in the same time.
  • Second: We needed several load balanced Solr databases.
  • Third: We needed to update all the databases and keep old data status.
  • If I don't speak about problems due to our lack of experience, the main Solr problem came from frequency of updates vs validation of several database. We encountered several locks due to this (our ops team didn't want to use real clustering, so all DB weren't updated). Problem messages were not always clear and we several days to understand the problems.

Kafka is quickly becoming core product of the organization, indeed it is replacing older messaging systems. No better alternatives found yet

We are using the Apache open source version of Kafka. The community is a good place to ask questions. and we can get most of our problems resolved there.

Alternatives Considered

Apache Kafka

I would only use RabbitMQ over Kafka when you need to have delay queues or tons of small topics/queues around.I don't know too much about Pulsar - currently evaluating it - but it's supposed to have the same or better throughput while allowing for tons of queues. Stay tuned - I might update this review after we finish evaluating Pulsar. It's much less battle-tested though.

Apache Solr

We have considering AWS search and Elastic search but decide to go with Solr as we need high speed and flexible query, and so far it meets all our requirement so we still continue with Solr.

Return on Investment

Apache Kafka

  • Positive impact on ROI since now we can use one large deployment of Apache Kafka that can be used for multiple scenarios ( storage systems, log aggregate, messaging queue ).
  • It is open-source so there are no licenses or subscription fees reducing the cost of deployment.
  • Data can now be ingested and analyzed in real-time making it easy to fine-tune the customer experience and decision making for internal IT.

Apache Solr

  • It's enabled us to deliver fast, relevant search results on our new website. The site is still in beta and being actively developed so our complete ROI is still unknown.
  • It integrates very well with Drupal so it has saved us from having to develop a custom solution.
