---------------------------
Summary: Remove unsupported compress type like GZIP, LZO etc
Key: IOTDB-1054
URL: https://issues.apache.org/jira/browse/IOTDB-1054
Project: Apache IoTDB
Issue Type: Improvement
Reporter: yuqi
It's seems that IOTDB only support SNAPPY、LZ4, but we can use other compress
type like
LZO, PAA, GZIP
When flush data to storage, exception will occur
for example:
{code:sql}
// Some comments here
public String getFoo()
{
return foo;
}
CREATE TIMESERIES root.ln.wf01.wt01.status WITH DATATYPE=BOOLEAN, ENCODING=PLAIN
CREATE TIMESERIES root.ln.wf01.wt01.temperature WITH DATATYPE=FLOAT,
ENCODING=RLE, COMPRESSOR = GZIP
INSERT INTO root.ln.wf01.wt01(timestamp,status,t1) values(200,false,20.71)
flush
{code}
{code:java}
