Database Entry

quasardb


QuasarDB is a high-performance, distributed, column-oriented database with native time series support. Transfers, computations, and aggregations are so fast that analysts can work interactively on their data, regardless of the amount stored.

Concurrency Control[03]


If two transactions attempt to write to the same entry, the first transaction to operate on the entry wins and the other transaction is canceled. When a transaction writes to an entry, other transactions may access the previous value of the entry.

Data Model


Isolation Levels[03]


Transactions in quasardb are snapshot based and provide repeatable reads.
