Summary:We investigate the Robinson--Schensted--Knuth algorithm (RSK) and Schutzenberger's jeu de taquin in the infinite setup. We show that the recording tableau in RSK defines an isomorphism of the following two dynamical systems: (i) a sequence of independent and identically distributed random letters equipped with Bernoulli shift, and (ii) a random infinite Young tableau (with the distribution given by Vershik--Kerov measure, corresponding to some Thoma character of the infinite symmetric group) equipped with jeu de taquin transformation. As a special case we recover the results on noncolliding random walks and multidimensional Pitman transform. [PUBLICATION ABSTRACT]
