We are developing a Big Data solution that has millions and millions of records and several TB in size utilizing a whole range of servers.
We are currently relying on some data in Percona/MySQL and migrate our solution to Cassandra/Solr/Datastax. An initial solution was developed that covers several use cases, but now our development team needs help with creating the queries for Cassandra/Solr based on how we currently work with MySQL.
You need to have a LOT of experience with Cassandra from a large scale environment with complex queries, lots of batch inserts/updates, real-time reads and advanced performance requirements.
Your task would be to advise our development team on how to best use Cassandra/Solr, optimize the configuration and write the required Cassandra/Solr queries based on existing MySQL queries.
There is an initial phase for the migration and then on-going work to develop new features.
If you are itnerested int his and have relevant experience with Big Data requirements, then please outline previous projects that you completed (in terms of size, amount of nodes, transactions/s etc.)
