Compatibility
ColumnPrefixFilter
Returns all columns whose names start with the specified string.
Supported
ColumnPaginationFilter
Returns a specified number of columns starting from a given column or offset.
Supported
FirstKeyOnlyFilter
Returns only the first Cell of each row.
Supported
KeyOnlyFilter
Does not return the value. The optional lenAsVal parameter replaces the value with its length.
Supported
RandomRowFilter
Retains rows randomly based on a given probability (sampling).
Supported
TimestampsFilter
Retains only the data within the given set of timestamps.
Supported
DependentColumnFilter
Returns other cells with the same timestamp based on a specified dependency column. Optionally excludes the dependency column itself and supports value comparison.
Supported
SingleColumnValueFilter
Filters rows by comparing the values of a specified column and retains that column for rows that meet the condition.
Supported
SingleColumnValueExcludeFilter
Filters rows by comparing the values of a specified column but excludes that comparison column.
Supported
ColumnRangeFilter
Retains only columns whose names fall within the specified range.
Supported
MultipleColumnPrefixFilter
Retains only columns whose names match any of the specified prefixes.
Supported
MultiRowRangeFilter
Retains only rows that fall within multiple RowRange intervals.
Supported
InclusiveStopFilter
Returns all rows up to and including the specified row.
Supported
FamilyFilter
Filters rows by comparing specific column family names.
Supported
FuzzyRowFilter
Filters row keys based on fuzzy matching rules.
Supported
ColumnValueFilter
Filters rows by comparing the values of a specified column.
Supported
FilterList
Supports arbitrary nested combinations of AND/OR and aligns semantically with HBase 2.6.

Note:
Filter only supports the BinaryComparator. Other Comparators, such as RegexStringComparator and SubstringComparator, are not currently supported.
Scan and Get operations can both use Filters.
Condition.filter is not supported.
