REST API Descargar ficheros por partes

dpardell — Tue, 24 Mar 2020 14:45:52 GMT
Hola,

estoy utilizando alfresco community 5.2 y el problema que tengo es que intento bajar un documento de 256 MB y el Alfresco me da un OutOfMemory al intentar cargar el archivo dentro de un ByteArrayOutputStream.

Hay alguna opción para poder bajar por partes un fichero con el alfresco, estoy utilizando el api REST.

He hecho la misma prueba con CMIS y funciona correctamente.

el error que sale al log con el api REST es este:
