How does PK chunking work in bulk API?
PK chunking works by adding record ID boundaries to the query with a WHERE clause, limiting the query results to a smaller chunk of the total results. The remaining results are fetched with extra queries that contain successive boundaries. The number of records within the ID boundaries of each chunk is referred to as the chunk size.
How to broadcast get data from API using Socket.IO?
I was thinking of having a nodejs server with a setInterval () that would be triggered every 2 seconds to perform an API request to a different server, get the data response and broadcast it to all socket.io clients. See where I was looking to broadcast the update_locations message. I was investigating how I should perform the request to my API?
What’s the default size of a chunk in PK?
Therefore, if soft-deleted records fall within a given chunk’s ID boundaries, the number of returned results is less than the chunk size. The default chunk size is 100,000, and the maximum size is 250,000. The default starting ID is the first record in the table.
How does PK chunking work in Microsoft Excel?
PK chunking works only with queries that don’t include SELECT clauses or conditions other than WHERE. PK chunking works by adding record ID boundaries to the query with a WHERE clause, limiting the query results to a smaller chunk of the total results.
When to enable PK chunking in Salesforce?
Salesforce recommends that you enable PK chunking when querying tables with more than 10 million records or when a bulk query consistently times out. However, the effectiveness of PK chunking depends on the specifics of the query and the queried data.
The new PK Chunking feature of the Bulk API automates this process by using the Primary Key (Record ID) of an object to break up the data into manageable chunks and query them separately. This feature is supported for all custom objects, many standard objects, and their sharing tables.
Why did pkchunking fail to create a batch?
PKChunking failed. InvalidJobState : Failed to create batch, since the Job is not Open. Current job state is ‘Closed’ I have used Bulk queries without PK chunking many times and have not seen that error.
What does PK stand for in PK chunking?
PK stands for Primary Key — the object’s record ID — which is always indexed. With this method, customers first query the target table to identify a number of chunks of records with sequential IDs.
How to split a query into smaller chunks?
By default the Bulk API will split the query into 100,000 record chunks – you can use the ‘ chunkSize ‘ header field to configure smaller chunks or larger ones up to 250,000. Larger chunk sizes will use up fewer Bulk API batches, but may not perform as well.
