这一期我们几位硅谷程序员讨论各自对近期科技行业大规模裁员的观察，看法和个人的应对措施。 Notes * [00:00] Guest intro. * [02:00] Layoff stories. * [16:45] Reasons, patterns, signals of a layoff. * https://news.shopify.com/changes-to-shopifys-team: We bet that the channel mix - the share of dollars that travel through ecommerce rather than physical retail - would permanently leap ahead by 5 or even 10 years. It’s now clear that bet didn’t pay off. * https://blog.google/inside-google/message-ceo/january-update/: Ensure that our people and roles are aligned with our highest priorities as a company. * https://techcrunch.com/2022/12/08/airtable-layoffs/: We’ve identified the teams best positioned to capture the opportunity in enterprise in order to bring complete focus, alignment and accountability in our execution. * [23:28] What explains recent tech layoffs, and why should we be worried? - Research says layoff does not reduce cost. * [24:10] Reason for layoff and hiring at the same time. * [25:40] Cash reserve != lower layoff probability * [27:00] Prioritize growth when money is cheap; prioritize “rule of 40” in today’s world. * [28:35] Layoff patterns at team level. You don’t know the truth of the “algorithm”. Decisions happen at Director+, even SVP level. Line managers and skip managers don’t have the layoff list. Data collection before executing the layoff. * [33:25] Meta vs Google layoff strategy difference. * [36:05] Avoid taking on risky projects. * [37:20] Survival tips for individual contributors * Layoffs are random. Always have a backup plan. * Business critical team; performance evaluation. * Importance of organizational visibility. * Be mentally prepared. * Do enough people work. * Follow the trend. * [48:00] Macro tech industry trend. * [52:08] Ending words.

这一期我们讨论Designing Data-Intensive Applications书中partitioning这一章的学习笔记。 🔴 这一期偏重技术话题，我们会用很多英文表述技术性专有名词。之前有朋友反馈过中英夹杂对大家收听不方便，希望在意的朋友见谅。如果有不准确或者过时的地方欢迎指正。 # Show Notes * 📕 Designing Data-Intensive Applications * What is partitioning? * A partition is a division of a logical database or its constituent elements into distinct independent parts. * Main reason: scalability - the query load can be distributed across many processors. * Youtube / Vitess scaling story * Single MySQL → Add read replica → Write can’t catchup up → Partition * How to partition? * Partitioning by Key Range (e.g., Bigtable) * Assign a continuous range of keys to each partition * Pro: range scan is easier, data locality * Cons: certain access patterns can lead to hot spots (timestamp) * Cons: finding split points and managing rebalancing is hard * Partitioning by Hash * Good hash function: uniformly distribute keys * Con: no easy range queries * Cassandra does KKV (partitioning key, sort key, value) * Hot spots: 3% of Twitter's Servers Dedicated to Justin Bieber * Secondary indexes: Local index * Efficient write, expensive read * ElasticSearch * Secondary indexes: Global index * Efficient read, expensive write * Using Global Secondary Indexes in DynamoDB (这里说错了，DynamoDB 支持 20 global secondary indexes per table） * Rebalancing partitions * Move loads to other nodes * Fixed number of partitions * New node steals partitions from every existing node * Notion: 480 partitions * Dynamic partitioning * 📈: split partition into 2 * 📉: merge 2 partitions into 1 * Fixed number of partitions per node * https://www.datastax.com/blog/new-token-allocation-algorithm-cassandra-30 * Operations: full automatic (dangerous) / semi-automatic / full manual (tedious) * Request Routing * 3 approaches: nodes talk to each other, separate routing tier, smart client * Separate coordination service such as ZooKeeper * Notes by xg # 联系方式 * 官网: eng.cafe * 微信公众号: Eng Cafe * Twitter: @engcafefm * Youtube: Eng Cafe * 小宇宙播客 * 泛用型播客客户端: eng.cafe/subscribe * Email: [email protected]
