With large result sets, the problems often is that drivers reads the full huge result sets into memory, and programs die of OOM.
It supports ACID transaction. When they need to do some modifications, infobright will use table lock for the whole table. Since B5 only match with C2 so Infobright only need to analyze values of Infobrignt of those package. Of couse, one can argue that my own users users of that driver are DBAs, programmers, consultants etc, people who use JDBC to write web apps.
Vlad, thanks for the extra info. Looking at the source codewe find following line that is unconditionally executed: The test program runs a query N times, and if the query was a select, it retrieves all values from the result set, using ResultSet. Would jdhc advise me technology for accessing Infobright from java. Join Stack Overflow to learn, share knowledge, and build your career. This knowledge grid is key structure for query and help to improve the query speed of infobright.
Data are stored in a column based way.
On performance of JDBC drivers.
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.
Infobright is good at supporting complex query.
Data Pack Nodes contain some necessary statistic information such as max, min, sum of the stored and compressed data which belong to this Data Pack Nodes. Anyway, great idea with respect to overriding the method. Ininfobright publish patent on data compression, query optimization and data organization.
On performance of JDBC drivers. The Infobright Optimizer can generate three type of Packs: The infobright incobright not have index explicitly.
On performance of JDBC drivers. –
I used my two favorite queries: Infobright support read committed model and read only. Since infobright does not support modified table and table content, all the query will read the table and when there is command like drop table, this query will lock the whole table. Slightly more on ConnectorJ vsor 2.
History Ininfobright was founded and issued jdvc first free release of its software in September and launched its community  at the same time and become an open source company at that time. But it indeed stores the knowledge grid in memory. This knowledge grid tries to minimize the number of decompress data as much as possible.
For example, suppose a query wants to find such data which the value of certain column is within a specific range. Database optimizers are continually improving. Infobright use columnar approach to manage database.
Infobright is a column-oriented, high performance analytic engine which is suitable for fast query of large amount of data. One day, when I have profiled those cases, it could make sense to write about it again.
Ifnobright use knowledge grid to do join.
