However, ClickHouse is super efficient for timeseries and provides “sharding” out of the box (scalability beyond one node). Although such databases can be very efficient with counts and averages, some queries will be slow or simply non existent. Inserts are efficient for bulk inserts only. created_utc?? ?

Soon after the financial crisis began in 2008, companies shifted attention from finance to operations. This limited the financial options companies could use to juice returns, so they focused on investing in operations to create efficiencies or fight for market share.

Microcomputers improved the efficiency of data collection and made it easy to consolidate operational data. Recessions in 2001 (when businesses reigned in unrestrained tech spending) and 2008 (when businesses reigned in all spending) tightened belts and increased operational scrutiny. Ironically, it had the opposite effect.

From 2008 to 2013, the Chrome project was based on WebKit, and a growing team of Chrome engineers began to contribute heavily "upstream." This arrangement is, however, maximally efficient in terms of staffing, as it means less expertise is duplicated across teams, requiring fewer engineers.

In tight times, businesses rely on efficiency, and IT investments will be expected to create a lot of that efficiency. We need to collect project data efficiently, otherwise our projects will suffer under the weight of data generation (or simply not report it). There’s a lot riding on IT in the current economic climate.

In 2008 or so, when data scientist emerged as a job title, it was widely ridiculed as a nonjob: the thought that people who just worked with data could be scientists, or employ the rigors of their time-honored methods, was literally laughable in many circles. To do so, we borrow metaphors from roles in other industries.

There is an alternative perspective that is far more optimistic : digital companies drive down costs through hyper-efficiency (speed, automation and machine scale) and price transparency. The argument for this invisible efficiency is that economic models have simply failed to change in ways that reflect this phenomenon.

As a result, management concerns itself with cost minimization and efficiency of expenditure. IT risks are much the same: we may aggressively manage scope or find some efficiency, but by and large these and many other factors will conspire to delay our projects. Robustness is the antithesis of efficiency. It's a guess.
