You can customize almost anything. Font colors, BG colors, size of the boxes, animation speeds, scroll speeds and more. It was created for our office (Polygon.io) but wanted others to be able to make it their own, for their use case.
Thanks for the info! This would be really interesting to try. The code is structured so that most would be reusable with a different rendering method. We may purchase a couple to try out.
I'm not sure I would call Cassandra slow. If the schemas are done well, it can be quite good for time series. Obviously this depends on the type of time series you're writing/querying.
Our biggest goal was writes & uptime. We sometimes do over 150k writes/sec. We also needed it to be up and accepting writes even if one node goes down.
We regularly take nodes offline for updates/etc and cassandra never misses a beat.
We ~really~ wanted to use influxdb, but as a startup we couldn't justify the cost/benefit over Cassandra since we have 8 nodes for the DB. I just went to the influx site to try to find the pricing again and it seems to be hidden now :/
EDIT: As a PS, just remember every one of the influxdb benchmarks ( that I've come across ) are single node. Cassandra is meant to be horizontally scalable. Testing a single node Cassandra is like testing a racecar on your driveway...
Both are open source, distributed ( must pay for influxdb ) databases. If you setup Cassandra's schemas correctly it can be good for time series. Influx is more suited to time series, however it's not 100% free and open source.
We offer free real-time forex streams ( polygon.io ). We are required to charge for equities because the actual exchanges charge us fees per use. Otherwise I would love it to all be free.
