Abstract:
Techniques are provided for maintaining data persistently in one format, but making that data available to a database server in more than one format. For example, one of the formats in which the data is made available for query processing is based on the on-disk format, while another of the formats in which the data is made available for query processing is independent of the on-disk format. Data that is in the format that is independent of the disk format may be maintained exclusively in volatile memory to reduce the overhead associated with keeping the data in sync with the on-disk format copies of the data. Selection of data to be maintained in the volatile memory may be based on various factors. Once selected the data may also be compressed to save space in the volatile memory. The compression level may depend on one or more factors that are evaluated for the selected data. The factors for the selection and compression level of data may be periodically evaluated, and based on the evaluation, the selected data may be removed from the volatile memory or its compression level changed accordingly.

Claim (Index 12):
The method of  claim 10 , wherein:\n the evaluation includes evaluating, for a certain data portion of the data portion, at least one of the following:\n access statistics of the certain data portion, \n a data type of the certain data portion, or \n performance statistics for one or more compressed data portions that are similar to the certain data portion; and \n the method further comprises:\n based on the evaluation, modifying a compression level for the certain data portion; \n compressing data in the certain data portion at the modified compression level; and \n loading the compressed data into the volatile memory.
