“@alexbfree @ThijsFeryn [ElasticSearch is] fine as long as data loss is acceptable. https://aphyr.com/posts/317-call-me-maybe-elasticsearch . We lose ~1% of all writes on average.”

Daragh O’Brien on the CJEU judgement on Safe Harbor
Many organisations I’ve spoken to have had the cunning plan of adopting model contract clauses as their fall back position to replace their reliance on Safe Harbor. [….] The best that can be said for Model Clauses is that they haven’t been struck down by the CJEU. Yet.

5 takeaways from the death of safe harbor – POLITICO
Reacting to the ruling, the [EC] stressed that data transfers between the U.S. and Europe can continue on the basis of other legal mechanisms. A lot rides on what steps the Commission and national data protection supervisors take in response. “It is crucial for legal certainty that the EC sends a clear signal,” said Nauwelaerts. That could involve providing a timeline for concluding an agreement with U.S. authorities, together with a commitment from national data protection authorities not to block data transfers while negotiations are on-going, he explained.
The New InfluxDB Storage Engine: A Time Structured Merge Tree
The new engine has similarities with LSM Trees (like LevelDB and Cassandra’s underlying storage). It has a write ahead log, index files that are read only, and it occasionally performs compactions to combine index files. We’re calling it a Time Structured Merge Tree because the index files keep contiguous blocks of time and the compactions merge those blocks into larger blocks of time. Compression of the data improves as the index files are compacted. Once a shard becomes cold for writes it will be compacted into as few files as possible, which yield the best compression.
