We want PlanetScale to be the best place to work. But every company says that, and very few deliver. Managers have a role in creating an amazing work experience, but things go awry when the wrong dynamic creeps in.

We have all seen those managers who collect people as “resources” or who control information as a way to gain “power.” In these cultures, people who “can’t” end up leading the charge. This is management mediocrity.

What will make us different? At PlanetScale, we won’t tolerate management mediocrity. We are building a culture where politics get you nowhere and impact gets you far. Managers are here to support people who get things done. They are as accountable to their team as their team is accountable to them.

We evaluate managers on the wellbeing and output of their team, how skillfully they collaborate with and influence others, and how inclusively and transparently they work.

You can expect your manager to:

• Perceive a better version of you and support you in getting there

ClickHouse administration tips.


CPU

SSE 4.2 instruction set support is required. Most recent (since 2008) CPUs have this instruction set.

When choosing between CPU with more cores and slightly less frequency and CPU with less cores and more frequency, choose first.
For example, 16 cores with 2600 MHz is better than 8 cores with 3600 MHz.
