* Minor bug fixes in GenericIndexed; Refactor and optimize GenericIndexed; Remove some unnecessary ByteBuffer duplications in some deserialization paths; Add ZeroCopyByteArrayOutputStream
* Fixes
* Move GenericIndexedWriter.writeLongValueToOutputStream() and writeIntValueToOutputStream() to SerializerUtils
* Move constructors
* Add GenericIndexedBenchmark
* Comments
* Typo
* Note in Javadoc that IntermediateLongSupplierSerializer, LongColumnSerializer and LongMetricColumnSerializer are thread-unsafe
* Use primitive collections in IntermediateLongSupplierSerializer instead of BiMap
* Optimize TableLongEncodingWriter
* Add checks to SerializerUtils methods
* Don't restrict byte order in SerializerUtils.writeLongToOutputStream() and writeIntToOutputStream()
* Update GenericIndexedBenchmark
* SerializerUtils.writeIntToOutputStream() and writeLongToOutputStream() separate for big-endian and native-endian
* Add GenericIndexedBenchmark.indexOf()
* More checks in methods in SerializerUtils
* Use helperBuffer.arrayOffset()
* Optimizations in SerializerUtils
* Simplify LikeFilter implementation of getBitmapIndex, estimateSelectivity.
LikeFilter:
- Reduce code duplication, and simplify methods, at the cost of incurring an extra box
of ImmutableBitmap into a SingletonImmutableList. I think this is fine, since this
should be cheap and the code path is not hot (just once per filter).
Filters:
- Make estimateSelectivity public since it seems intended that they be used by Filter
implementations, and Filters from extensions may want to use them too. Removed
@VisibleForTesting for the same reason.
- Rename one of the estimatePredicateSelectivity overloads to estimateSelectivity, since
predicates aren't involved.
* Address PR comments.
* Remove unused import
* Change List to Collection
* Enable parallel test
* Remove unnecessary NotThreadSafe annocation
* Randomize the start port when finding available ports
* Fix test failure
* Change to handle all negatives
* Deduplicate looking for bitset.nextSetBit() in BitSetIterator.next() and hasNext()
* Add BitmapIterationTest
* More elaborate comment on why Roaring is not tested in BitmapIterationTest
