[2] In the context of Apache HBase, "durably on disk" implies an hflush() call on the transaction log. This does not actually imply an fsync() to magnetic media, but rather just that the data has been written to the OS cache on all replicas of the log.

Transactions (beta) Above and beyond the row-level transactional semantics of HBase, Phoenix adds cross row and cross table transaction support with full ACID semantics by integrating with Tephra, now an Apache incubator project. Tephra provides snapshot isolation of concurrent transactions by implementing multi-versioned concurrency control.

Mar 21, 2012 · HBase supports ACID in limited ways, namely Puts to the same row provide all ACID guarantees. (HBASE-3584 adds multi op transactions and HBASE-5229 adds multi row transactions, but the principle remains the same) So how does ACID work in HBase? HBase employs a kind of MVCC. And HBase has no mixed read/write transactions.Author: Lars Hofhansl

Jun 10, 2015 · We chose Apache HBase as the storage layer for the queue. It is designed and optimized for strong row-level consistency and horizontal scalability. It provides very good concurrent write performance and its support of ordered scans fits well for a partitioned consumer. We use the HBase Coprocessors for efficient scan filtering and queue cleanup.

Transactions. While HBase provides row-level transactions, Phoenix integrates with Tephra to add cross-row and cross-table transaction support with full ACID semantics. As with traditional SQL transactions, transactions provided through the Phoenix transaction manager allow you to ensure an atomic unit of data is successfully upserted, rolling ...
