Summary: Dictionary encoding
Key: IOTDB-1403
URL: https://issues.apache.org/jira/browse/IOTDB-1403
Project: Apache IoTDB
Issue Type: New Feature
Reporter: Liu Jiajun
Currently, TEXT is not encoded in IoTDB. While this approach works fine for
data with low repetitive patterns, it may result in storage inefficiency and
I/O overhead for low-cardinality data, where repetitions happen frequently. To
this end, we propose supporting dictionary encoding for TEXT data type, which
could provide higher compression rate and faster deserialeraliziation for
low-cardinality data.
