We present the joint analysis of the X-ray and SZ signals in A2319, thegalaxy cluster with the highest signal-to-noise ratio in Planck maps and thathas been surveyed within our XMM Cluster Outskirts Project (X-COP). We recoverthe thermodynamical profiles by the geometrical deprojection of the X-raysurface brightness, of the SZ comptonization parameter, and an accurate androbust spectroscopic measurements of the temperature. We resolve the clumpinessof the density to be below 20 per cent demonstrating that most of thisclumpiness originates from the ongoing merger and can be associated tolarge-scale inhomogeneities. This analysis is done in azimuthally averagedradial bins and in eight independent angular sectors, enabling us to study indetails the azimuthal variance of the recovered properties. Given the exquisitequality of the X-ray and SZ datasets, we constrain at $R_{200}$ the totalhydrostatic mass, modelled with a NFW profile, with very high precision($M_{200} = 9.76 \pm 0.16^{stat.} \pm 0.31^{syst.} \times 10^{14} M_\odot$). Weidentify the ongoing merger and how it is affecting differently the gasproperties in the resolved azimuthal sectors. We have several indications thatthe merger has injected a high level of non-thermal pressure in this system:the clumping free density profile is above the average profile obtained bystacking Rosat observations; the gas mass fraction exceeds the expected cosmicgas fraction beyond $R_{500}$; the pressure profile is flatter than the fitobtained by the Planck collaboration; the entropy profile is flatter than themean one predicted from non-radiative simulations; the analysis in azimuthalsectors has revealed that these deviations occur in a preferred region of thecluster. All these tensions are resolved by requiring a relative support ofabout 40 per cent from non-thermal to the total pressure at $R_{200}$.
