+## Benchmark: ClickHouse Vs. InfluxDB Vs. Postgresql Vs. Parquet 
 
+-----
 
+#### How to use:
+* Rename the file "properties-model.ini" to "properties.ini"
+* Fill with your own credentials
+----
 
-### Git History:
-```Bash
-git add
-git add properties-model.ini 
-git add compareDBs.ipynb 
-git status
-git commit
-```
+The proposal of this work is to compare the speed in read/writing a midle level of data ( a dataset with 9 columns and 50.000 lines) to four diferent databases:
+* ClickHouse
+* InfluxDB
+* Postgresql
+* Parquet (in a S3 Minio Storage)
+* DuckDB with Polars
+* MongoDB
+* Kdb+
+
+ - [ ] Clickhouse read
+ 
+Deve-se relevar:
+é uma "cold-storage" ou  "frezze-storage"
+influxdb: alta leitura etem a vantagem da indexaçõa para viizualização de dados em gráficos
+
+notas: 
+* comparar tamanho do csv com parquet
