How do I change the write-block-size configuration?

Detail

Answer

To update the write-block-size setting:

1. Open /etc/aerospike/aerospike.conf.

2. Configure the namespaces write-block-size to the new desired size. Note that this configuration is placed inside the storage-engine device stanza. This is not applicable for storage-engine memory.

3. Restart the server .

4. Continue with other nodes in the cluster.

Notes

The write-block-size configuration is static but can be changed in a rolling manner across all nodes in a cluster. 

• When increasing the write-block-size the max-record-size parameter should be set so that larger records are not written until all nodes have the larger block size.
• If decreasing the write-block-size , it is necessary to first delete all the records that are bigger than the new lower write-block-size and also zeroize the disks which will require to wait for migrations to complete between each node.
• The default value for write-block-size  is 1MB and the configured value of this parameter must be a power of 2, so the different options are: 128K, 256K, 512K, 1M (and 2M, 4M or 8M from version 4.2)
