All Work and No Play Makes Scylla a Dull Monster

Following a week of Scylla hands-on training, Scylla Summit, and internal meetings, the associates of ScyllaDB had two days to relax, unwind, and have fun in the beautiful city of Sonoma. Over the past year ScyllaDB’s team has grown by 68% which meant a large contingent coming to Scylla Summit were new!

SaaS vs OSS – Fight or flight, round #2

To quote Bob Dylan, “the times they are a changin’.” Microsoft loves Linux, IBM buys Red Hat, RedisLabs changes their module license to Commons Clause, Mongo invents Server Side Public License (SSPL) and moves from AGPL, AWS open sources Firecracker and releases a Kafka service, and the hot news from Friday, Confluent changes its license for components of the Confluent Platform from Apache 2.0 to the Confluent Community License.

Spark and Scylla: Part 3

Spark and Scylla: Spark DataFrames in Scylla Welcome back! Last time, we discussed how Spark executes our queries and how Spark’s DataFrame and SQL APIs can be used to read data from Scylla. That concluded the querying data segment of the series; in this post, we will see how data from DataFrames can be written back to Scylla. As always, we have a code sample repository with a docker-compose.yaml file with all the necessary services we’ll need. After you’ve cloned it, start up the services with docker-compose: After that is done, launch the Spark shell as in the previous posts […]
