hi,
followed your advice and openend for each write operation a separate session
(as i didn´t found the SessionPool).
The result was the same.
Here is the relevant python code excerpt:
```python
import datetime
from datetime import datetime
from iotdb_session.utils.IoTDBConstants import *
from iotdb_session.utils.Tablet import Tablet
from iotdb_session.Session import Session
def open_connection():
try:
connection = Session(host="127.0.0.1", port="6667", user='root',
password='root')
connection.open(False)
except Exception as e:
print( e )
connection.close()
return connection
```
param: data is an array with the following structure
[
[12345678,1.3,1.0],
[12345678,1.3,1.0]
]
param device_id e.g. root.storagegroup.city.device0020
```python
def save_tablet(device_id, data):
measurements_ = []
values = []
data_types_ = []
timestamps = []
measurements_.append("comsumption")
measurements_.append("status")
data_types_.append(TSDataType.FLOAT)
data_types_.append(TSDataType.FLOAT)
for datapoint in data:
values.append([datapoint[1], datapoint[2]])
timestamps.append(datapoint[0])
tablet_ = Tablet(device_id, measurements_, data_types_, values,
timestamps)
try:
connection = open_connection()
connection.insert_tablet(tablet_)
connection.close()
except Exception as e:
print('an error occured')
print(e)
connection.close()
def create_data(ts_prefix, amount_timeseries):
data = create_timeseries_data(154630080, amount)
for index in range(1, amount_timeseries):
device_id = ts_prefix + index
save_tablet(device_id, data)
```

HTHou commented on issue #2131: URL: https://github.com/apache/iotdb/issues/2131#issuecomment-734380751 Hi, I think `RLE` is not a good choice for high precision. If you looking for high precision, better to use `GORILLA` instead. Please see this doc on website for more information of the encoding precision. https://iotdb.apache.org/UserGuide/Master/Concept/Encoding.html The reason why `select last` doesn't loss precision is the result is cached when the data insert. :) This is an automated message from the Apache Git Service.

[GitHub] [iotdb] 140378476 opened a new issue #2132: Incorrect result returned by `getFloat` in JDBC.
140378476 opened a new issue #2132:
URL: https://github.com/apache/iotdb/issues/2132
**Describe the bug**
I got clearly incorrect results when retrieving data using method
`getFloat`.
Addtionally, I can get a String representation of the data, which is highly
inprecise and requires extra parsing.
**To Reproduce**
Steps to reproduce the behavior:
1. Create timeseries: ` CREATE TIMESERIES root.t.d WITH DATATYPE=FLOAT,
ENCODING=RLE`
2. Insert data: `INSERT INTO root.t(timestamp,d) VALUES(1,1.23456789)`
3. Retrieve data using JDBC: (mostly copied from the user guide and
converted to Kotlin)
```
fun getConnection(): Connection? {
// JDBC driver name and database URL
val driver = "org.apache.iotdb.jdbc.IoTDBDriver"
val url = "jdbc:iotdb://127.0.0.1:6667/"
// Database credentials
val username = "root"
val password = "root"
var connection: Connection? = null
try {
Class.forName(driver)
connection = DriverManager.getConnection(url, username, password)
} catch (e: ClassNotFoundException) {
e.printStackTrace()
} catch (e: SQLException) {
e.printStackTrace()
}
return connection
}
fun select(){
val connection = getConnection()
if (connection == null) {
println("get connection defeat")
return
}
val statement: Statement = connection.createStatement()
statement.execute("SELECT d from root.test")
val rs = statement.resultSet
rs.next()
println("String:")
println(rs.getString(2))
println("Float:")
println(rs.getFloat(2))
}
```
4. The output is:
```
String:
1.23
Float:
1.06728262E9
```
I got the approximately correct result from `getString()` but incorrect
result from `getFloat()`.
**Expected behavior**
I should get a precise float result from `getFloat()`.
**Desktop (please complete the following information):**
- OS: [e.g. iOS]
- Browser [e.g. chrome, safari]
- Version [e.g. 22]
**Additional context**
The inplementation in `IoTDBRpcDataSet.java` shows that it just converts
the bytes to float in the method, while the bytes are actually in the format
of String.
A further dig into the source code shows that all data are in the format of
String except the timestamp.
Therefore, a simple fix is not possible because the issue is that the raw
data transferred from the
database is in the format of String.
This can cause precision loss and significant performance issue(extra
parsing and formatting, more transfer cost).

140378476 opened a new issue #2131: URL: https://github.com/apache/iotdb/issues/2131 **Describe the bug** 1. I can not get precise result of float values using `select` query. 2. When executing `select` and `select last`, I got float values in different precisions. **To Reproduce** Steps to reproduce the behavior: 1. Create timeseries: ` CREATE TIMESERIES root.t.d WITH DATATYPE=FLOAT, ENCODING=RLE` 2. Insert data: `INSERT INTO root.t(timestamp,d) VALUES(1,1.23456789)` 3. Select data: `SELECT * FROM root.t`, the returned value is `1.23`. 4. Select data using last: ` SELECT LAST * FROM root.t`, the returned value is `1.2345679`. **Expected behavior** It should return at least the precise float value instead of an approximate one. The result is expected to at least be the same as the returned value using select last. **Screenshots**  **Desktop (please complete the following information):** - OS: Windows10 - Version iotdb 0.10.1 **Additional context** No This is an automated message from the Apache Git Service.
