# Reading from Freshsales entities
<a name="freshsales-reading-from-entities"></a>

**Prerequisite**

A Freshsales object you would like to read from. You will need the object name.

**Supported entities for source**:


| Entity | Can be filtered | Supports limit | Supports Order by | Supports Select \$1 | Supports partitioning | 
| --- | --- | --- | --- | --- | --- | 
| Accounts | Yes | Yes | Yes | Yes | Yes | 
| Contacts | Yes | Yes | Yes | Yes | Yes | 

**Example**:

```
freshSales_read = glueContext.create_dynamic_frame.from_options(
     connection_type="freshsales",
     connection_options={
         "connectionName": "connectionName",
         "ENTITY_NAME": "entityName",
         "API_VERSION": "v1.0"
     }
```

**Freshsales entity and field details**:

Freshsales provides endpoints to fetch metadata dynamically for supported entities. Accordingly, operator support is captured at the datatype level.

## Partitioning queries
<a name="freshsales-reading-partitioning-queries"></a>

**Filter-based partitioning**:

You can provide the additional Spark options `PARTITION_FIELD`, `LOWER_BOUND`, `UPPER_BOUND`, and `NUM_PARTITIONS` if you want to utilize concurrency in Spark. With these parameters, the original query would be split into `NUM_PARTITIONS` number of sub-queries that can be executed by Spark tasks concurrently.
+ `PARTITION_FIELD`: the name of the field to be used to partition the query.
+ `LOWER_BOUND`: an **inclusive** lower bound value of the chosen partition field.

  For the Datetime field, we accept the value in ISO format.

  Examples of valid value:

  ```
  "2024-09-30T01:01:01.000Z"
  ```
+ `UPPER_BOUND`: an **exclusive** upper bound value of the chosen partition field.
+ `NUM_PARTITIONS`: the number of partitions.

Example:

```
freshSales_read = glueContext.create_dynamic_frame.from_options(
     connection_type="freshsales",
     connection_options={
         "connectionName": "connectionName",
         "ENTITY_NAME": "entityName",
         "API_VERSION": "v1",
         "PARTITION_FIELD": "Created_Time"
         "LOWER_BOUND": " 2024-10-15T21:16:25Z"
         "UPPER_BOUND": " 2024-10-20T21:25:50Z"
         "NUM_PARTITIONS": "10"
     }
```
