Hi,
Carbon Data is not supporting Float Data type.
Do we need to fix this Jira issue [CARBONDATA-390]
<https://issues.apache.org/jira/browse/CARBONDATA-390>?
I think float data type should have its own range.
So do we need to support range for Float data type?
Proposed Solution :

Try Code like this:
```
if (cc.tableNames().filter(f => f == _cfg.get("tableName").get).size == 0) {
df.sqlContext.sql(s"DROP TABLE IF EXISTS
${_cfg.get("tableName").get}")
writer.options(_cfg).mode(SaveMode.Overwrite).format(_format).save()
} else {
Thank you for the response Liang. I think I have followed the example but
it still returns error:
Data loading failed. table not found: default.carbontest
attached my code below: I read data from a hive table with HiveContext and
convert it to CarbonContext then generate the df and save to
Hi Lionel
Don't need to create table first, please find the example code in
ExampleUtils.scala
df.write
.format("carbondata")
.option("tableName", tableName)
.option("compress", "true")
.option("useKettle", "false")
.mode(mode)
.save()
Preparing API docs is in progress.
Hi team,
I'm trying to save spark dataframe to carbondata file. I see the example in
your wiki
option("tableName", "carbontable"). Does that mean I have to create a
carbondata table first and then save data into the table? Can I save it
directly without creating the carbondata table?
the code is

Hi All
I would like to propose following new features in Carbon data
1) Update statement to support modifying existing records in carbon data
table
2) Delete statement to remove records from carbon data table
A) Update operation: 'Update' features can be added to CarbonData using
intermediate

The proposed change is reasonable, +1.
But is there a plan to make the reader backward compatible with the old format?
So the impact to the current deployment is minimum.

Jacky

Dear Jacky,
Yes I am planning to support both data format reader(new and
old) + writer(new and old), default new writer will be enabled, but if user
wants to write in older format for that i will expose one configuration.
Please let me know if you have any other suggestion.

Hello All,
Improving carbon first time query performance
Reason:
1. As file system cache is cleared file reading will make it slower to read
and cache
2. In first time query carbon will have to read the footer from file data
file to form the btree
3. Carbon reading more footer data than its
The key in the map can be only primitive data types. At present, Carbon
Data supports following primitive data types Integer, String, Timestamp,
Double and Decimal.
If in future CarbonData adds supports more primitive data types, the same
can be used as key in the Map.

Hi All,
This discussion is regarding support for Map Data type in Carbon Data.
Carbon Data supports complex and nested data types such as Arrays and
Struts. However, Carbon Data does not support other complex data types such
as Maps and Union which are generally supported by popular opensource
