Accumulo implementation of AgeOffFilter, based on an expiry.
Runs at the bottom of the iterator stack - takes the index simple feature type and adds the value from the row key
Aggregating iterator - only works on kryo-encoded features
Iterator that computes and aggregates 'bin' entries
Age off data based on the dtg value stored in the SimpleFeature
Iterator that operates on kryo encoded attribute index rows.
Iterator that operates on kryo encoded attribute index rows. It will modify the value (kryo encoded simple feature) by setting the attribute from the row key.
It is expected to run *after* the normal iterator stack - thus the key value received in getTopValue will be the already transformed feature result, with a null value for the attribute in question. This iterator will set the attribute value based on the row, then re-serialize the feature
Aggregating iterator - only works on kryo-encoded features
Density iterator - only works on kryo-encoded features
Iterator that operates on kryo encoded values.
Iterator that operates on kryo encoded values. It will: a) evaluate the feature against an optional filter b) apply an optional transform
Uses lazy evaluation of attributes and binary transforms when possible.
Reads simple features and observe them with a Stat server-side
Reads simple features and observe them with a Stat server-side
Only works with z3IdxStrategy for now (queries that date filters)
Assumes cq are byte-encoded attribute number
Aggregates bins that have already been computed as accumulo data values
Density iterator that weights hits based on z2 schema
Density iterator that weights hits based on z3 schema
Accumulo implementation of AgeOffFilter, based on an expiry. Features with a timestamp older than the expiry will be aged off.
This iterator can be configured on scan, minc, and majc to age off data
Age off iterators can be stacked but this may have performance implications
