@dittycheria A decline in ability to monopolise the world's most ambitious and brilliant minds. But also new, vibrant tech ecosystems in Europe, India, and the rest of the world. Being able to build a meaningful business or career without moving to SF or NY is only a net positive for humanity

Heading to Las Vegas for #GoogleCloudNext . If you're attending it, I'd welcome the chance to connect. Send me a DM, or visit the @cratedb team and me at booth #1925. Let's explore how we can tackle your real-time analytics and search challenges together.

[Sergey Gerasimenko @geragray]

It was great to catch up with an old friend Vasco Duarte, on the @ScrumPodcast and do a bit of shameless self-promotion with CrateDB - the rising strategy in real-time analytics and search category.

Listen to the full episode here https://t.co/XUCEAkTaFh or on your podcast app.

CrateDB has been recognized in DBTA's Trend-Setting Products in Data and Information Management for 2025. https://t.co/TF5p6irNjt. Can't be excited more for next year's product launches we are working on.

@omarmhaimdat @typesense @ClickHouseDB @cratedb @ScyllaDB @elastic @PostgreSQL CrateDB was started partly because the founding team liked @elastic but found it complex to operate. Today, we consider the "ease of use" of managing a large cluster our competitive advantage. That is if you want to self-manage of course, otherwise there is CrateDB Cloud.

@1999Yadwade @MichaelDrogalis Thanks @1999Yadwade. CrateDB It is the only other database on the market offering automatic indexing of all fields by default (@RocksetCloud calls it Converged index, we call it hybrid indexing), which enables fast analytical queries on any kind of data. https://t.co/E7m5rX18AN

@paschalis_dim @ClickHouseDB @cratedb @awscloud I bet on @cratedb. It is the only other database on the market offering automatic indexing of all fields by default (@RocksetCloud calls it Converged index, we call it hybrid indexing), which enables fast analytical queries on any kind of data. More here https://t.co/E7m5rX18AN

[Sergey Gerasimenko @geragray]

We see that @cratedb has 6-9x lower latency and outperforms @RocksetCloud on Rockbench. Join us on Thursday 25th to learn more about our unique approach to indexing data and use cases where CrateDB is the best replacement. Plus AMA. Developers welcome!

If you are @RocksetCloud customer @cratedb is an eventually consistent distributed SQL database that indexes all data in real-time (text, vector, geospatial, time-series, and JSON) for fast search and ad hoc query execution at any scale. Also open-source. https://t.co/sJmUlrBcIG

#MongoDB loves its #developers. They are the source of our success. Would you like to come and lead the teams that develop the docs, courses, articles, forums, and everything else at the center of showing that love and building that community?

[Sergey Gerasimenko @geragray]

We are looking for a Developer Productivity engineer to help us with optimizing @realm CI, expanding it to support new SDKs (Unity, Raspberry Pi, Dart/Flutter) and simplifying it for the open-source contributors. Fully remote position anywhere in EMEA. https://t.co/TvXjoU9sjS
