Change subject: [ASTERIXDB-3141][ASTERIXDB-3134] Allow querying columnar
datasets
......................................................................
[ASTERIXDB-3141][ASTERIXDB-3134] Allow querying columnar datasets
- user model changes: yes
- storage format changes: no
- interface changes: yes
Details:
This patch adds the ability to query columnar datasets.
Also, it teaches the compiler to read only the requested
columns. This patch also includes the ability to filter
mega-leaf nodes given a query predicate.
Interface changes:
- IMetadataProvider#getScannerRuntime()
* To allow projections for both data records and meta records
- IProjectionInfo
* Renamed to IProjectionFiltrationInfo
* Added getFilterExpression() for columnar filters
User model changes:
- After this change you can create columnar datasets
Example:
CREATE DATASET ExperDataset(ExperType)
PRIMARY KEY uid AUTOGENERATED
WITH {
"dataset-format":{"format":"column"}
};
- Added compiler property:
* compiler.column.filter
to enable/disable the usage of columnar filter
- Added storage properties:
* storage.column.max.tuple.count
An integer to tell the maximum number of
tuples to store per mega leaf node
* storage.column.free.space.tolerance
the percentage of tolerable empty space to
minimize column splitting
