This page describes different types of limits for Pinecone Database.

​
Rate limits

Rate limits are restrictions on the frequency of requests within a specified period of time. Rate limits vary based on pricing plan and apply to serverless indexes only.

​
Read units per month per project

This limit applies to organizations on the Starter plan only.
Starter planStandard planEnterprise plan
1,000,000N/AN/A

Read units measure the compute, I/O, and network resources used by fetch, query, and list requests to serverless indexes. When you reach the monthly read unit limit for a project, fetch, query, and list requests to serverless indexes in the project will fail and return a 429 - TOO_MANY_REQUESTS status with the following error:

Request failed. You've reached your read unit limit for the current month limit. 
To continue reading data, upgrade your plan.

To continue reading from serverless indexes in the project, upgrade your plan.

To check how close you are to the monthly read unit limit for a project, do the following:

  1. Open the Pinecone console.
  2. Select the project.
  3. Select any index in the project.
  4. Look under Starter Usage.

​
Write units per month per project

This limit applies to organizations on the Starter plan only.
Starter planStandard planEnterprise plan
2,000,000N/AN/A

Write units measure the storage and compute resources used by upsert, update, and delete requests to serverless indexes. When you reach the monthly write unit limit for a project, upsert, update, and delete requests to serverless indexes in the project will fail and return a 429 - TOO_MANY_REQUESTS status with the following error:

Request failed. You've reached your write unit limit for the current month. 
To continue writing data, upgrade your plan.

​
Upsert size per second per namespace

Starter planStandard planEnterprise plan
50 MB50 MB50 MB

When you reach the per second upsert size for a namespace in an index, additional upserts will fail and return a 429 - TOO_MANY_REQUESTS status with the following error:

Request failed. You've reached the max upsert size limit per second for index <index name>. 
Pace your upserts or upgrade your plan.

To increase this limit, upgrade your plan. Otherwise, you can handle this limit by automatically retrying requests with an exponential backoff.

​
Query read units per second per index

Starter planStandard planEnterprise plan
2,0002,0002,000

Pinecone measures query usage in read units. When you reach the per second limit for queries across all namespaces in an index, additional queries will fail and return a 429 - TOO_MANY_REQUESTS status with the following error:

Request failed. You've reached the max query read units per second for index <index name>. 
Pace your queries.

To handle this limit, automatically retry requests with an exponential backoff.

To check how many read units a query consumes, check the query response.

​

​
Operation limits

Operation limits are restrictions on the size, number, or other characteristics of operations in Pinecone. Operation limits are fixed and do not vary based on pricing plan.

​
Upsert limits

MetricLimit
Max upsert size2MB or 1000 records
Max metadata size per record40 KB
Max length for a record ID512 characters
Max dimensionality for dense vectors20,000
Max non-zero values for sparse vectors1000
Max dimensionality for sparse vectors4.2 billion

When upserting larger amounts of data, it is recommended to upsert records in large batches. A batch of upserts should be as large as possible (up to 1000 records) without exceeding the maximum request size of 2MB.

To understand the number of records you can fit into one batch based on the vector dimensions and metadata size, see the following table:

DimensionMetadata (bytes)Max batch size
38601000
768500559
15362000245

​
Query limits

MetricLimit
Max top_k value10,000
Max result size4MB

The query result size is affected by the dimension of the dense vectors and whether or not dense vector values and metadata are included in the result.

If a query fails due to exceeding the 4MB result size limit, choose a lower top_k value, or use include_metadata=False or include_values=False to exclude metadata or values from the result.

​
Fetch limits

Limit
Max records per fetch request1,000

​
Delete limits

DeleteLimit
Max records per delete request1,000

​
Identifier limits

An identifier is a string of characters (up to 255 characters in length) used to identify “named” objects in Pinecone. The following Pinecone objects use strings as identifiers:

ObjectFieldMax # charactersAllowed characters
