MongoDB is an important database, and this paper explains the tunable (per-operation) consistency models that MongoDB provides and how they are implemented under the covers. Microsoft have a paper describing their new recovery mechanism in Azure SQL Database , the key feature being that it can recovery in constant time. On one of the themes that captures my imagination, how changing hardware platform influence system design: Rethinking database high availability with RDMA networks. MORE

David Gerard : Companies are shocked to realise that blockchain — an expensive and useless idea that has soaked up millions of dollars for zero return — may not be a good technology. “Many companies will halt their blockchain tests this year. Alok Pathak : While both (Multi-AZ and Read replica) maintain a copy of database but they are different in nature.

So, in the spirit of things, we’ve laid out a few New Year’s resolutions that all database professionals can take into account as they look to turn over a new leaf in 2018 and build on their successes. From the IoT , to 5G , to blockchain , it seems like we’re on the precipice of seeing some truly game-changing technologies come into their own; you don’t want to be left behind when they finally do breakthrough.

A major component to the system that HARA created is blockchain. HARA has had to develop additional technologies to make their application work on Ethereum, a popular, open source, blockchain framework Last year, I spent some time in Jakarta visiting HARA , an AWS customer. They've created a way to connect small farms in developing nations to banks and distributers of goods, like seeds, fertilizer, and tools. MORE

Blockchain Technology Cryptocurrencies like Bitcoin rely on blockchains, but web developers are just realizing the full potential of this technology. IBM, Microsoft, and Amazon are all exploring new ways to use blockchains in 2019. If you have a large database of user information stored on your servers, consider introducing multi-factor identification. Smart developers are always looking ahead for ways to adapt in the ever changing world of web development. MORE

Fine-grained, secure and efficient data provenance on blockchain systems Ruan et al., We haven’t covered a blockchain paper on The Morning Paper for a while, and today’s choice won the best paper award at VLDB’19. That’s hard to do in today’s blockchain systems for two reasons: Provenance can only be determined by querying and replaying all on-chain transactions, which is inefficient and an offline activity. For permissioned blockchains we’re all set. MORE

Micropayments require an environment of trust, and in a decentralised context that leads us to blockchains. A blockchain holds the metadata catalog for the system (participants register on the blockchain for discovery purposes) and also provides the trust and dispute resolution anchor for micropayments. Groups can be centralised or decentralised, with decentralised groups managed by smart contracts on the AnyLog blockchain. Uncategorized Blockchain Datastores MORE

What if we use ClickHouse (which is a columnar analytical database) as our main datastore? Well, typically, an analytical database is not a replacement for a transactional or key/value datastore. how many messages was send for some time period and how much it cost) and a typical key/value queries like: “return 1 message by the message id” Using a columnar analytical database can be a big challenge here.
