Redis Persistence Demystified
TL;DR:
even if Redis is an in memory database it offers good durability compared to other on disk databases.
But you must read the post for all the nitty-gritty.

Induction: SQL? NoSQL? Explore, Query, Visualize
Matt Thompson‘s Induction is a free OS X application allowing access and visualization of data stored in PostgreSQL, MySQL, SQLite, Redis, and soon MongoDB.

Some are asking for a common NoSQL query language, some are trying to put a tabular format on top of NoSQL data, and some are building an indirection layer as a tool.

Jelastic Database Marketshare: MySQL, MongoDB, MariaDB
Jelastic, a company offering a cloud platform for Java server hosting, has published some stats about the databases used by their over 7000 users:

While it would be wrong to generalize these results to absolute database marketshare, it is interesting nonetheless to see that MongoDB is already outrunning PostrgeSQL being the second most used database and that CouchDB, which was added only one month ago, is already used by 5% of Jelastic’s users. MySQL detains the first position with over 40% users or differently put double the number of the second place (MongoDB).
These numbers would be even more interesting if they would account for some real usage stats like database sizes or query volumes.

Standalone Heroku Postgres’ Unanswered Question
While the offer is clear and valuable in itself:
- 99.99% uptime
- 99.999999999% (eleven nines) durability
- read-only asynchronous replicas
- database cloning
I’ve been reading all posts about the announcement looking for the answer to the most obvious question: why would you use Heroku’s Postgres service from outside the Heroku platform?
As far as I can tell:
- the network latency will be significant
- network partitions will occur (more often than having both you application and data in the same DC)
- transfer costs will be significant
So what is the answer?
