Two-Phase Locking Deadlock Detection. For the first reason, different from row based storage database where each metadata contains different data types, the column orientation database contains one data type and this property can help to optimize the compression algorithm for different types of data. Not only is infobright is fast at query, the data compression is much higher than database engine. Below is sample code for stored Procedures for Infobright: Infobright handle the query like this: Anyway, great idea with respect to overriding the method.

System Properties Comparison Infobright vs. MySQL vs. PostgreSQL

As a result, each column has the same number of rows and this column structure is better at data compression compared with row-oriented database. When they need to do some modifications, infobright will use table lock for the whole table.

The test program runs a query N times, and infonright the query was a select, it retrieves all values from the result set, using ResultSet. Infobright use columnar approach to manage database. For professional support services, see the list of MariaDB service providers.

As far as I understand I should use plain jdbc connection and execute queries, not making use of high level thing like hibernate.

In theory, since the MariaDB driver has a Drizzle JDBC heritage, the performance characteristics should be similar, but they are not, so there must be a bug somewhere. With large result sets, the problems often is that drivers reads the full huge result sets infobrkght memory, and programs die of OOM.

In addition to that, infobright support approximate query which can greatly reduce the query time for massive amount of data. Not bad for a single line fix. In this way, infobright can get a market-leading data compression ratio from Have you done such infpbright
