**Zoho CRM field details**:

Zoho CRM provides endpoints to fetch metadata dynamically for supported entities. Therefore, operator support is captured at the datatype level.

[\[See the AWS documentation website for more details\]](http://docs.aws.amazon.com/glue/latest/dg/zoho-crm-reading-from-entities.html)

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

Partitioning is not supported in Async mode.

**Filter-based partitioning (Sync mode)**:

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 Spark timestamp format used in Spark SQL queries.

  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:

```
zoho_read = glueContext.create_dynamic_frame.from_options(
    connection_type="zohocrm",
    connection_options={
        "connectionName": "connectionName",
        "ENTITY_NAME": "entityName",
        "API_VERSION": "v7",
        "PARTITION_FIELD": "Created_Time"
        "LOWER_BOUND": "2022-01-01T01:01:01.000Z"
        "UPPER_BOUND": "2024-01-01T01:01:01.000Z"
        "NUM_PARTITIONS": "10"
    }
```
